Breast Cancer Symptoms - What You Need to Know (part 2)

Part 1 - Part 2
By the National Cancer Institute
    Hormonal Replacement Therapy - HRT Cancer Links
    Hormonal therapy keeps cancer cells from getting the natural hormones (estrogen and progesterone) they need to grow. If lab tests show that the breast tumor has hormone receptors, the woman may have hormonal therapy. Like chemotherapy, hormonal therapy can affect cells throughout the body.
    This treatment may be a medicine or surgery:
    • Medicine: The doctor may suggest a drug that can block the natural hormone. One example is tamoxifen, which blocks estrogen. Another type (aromatase inhibitor) prevents the body from making the female hormone estradiol, a form of estrogen.
    • Surgery: If a woman has not gone through menopause, she may have surgery to remove her ovaries. The ovaries are the main source of the body's estrogen. (After menopause, hormone production by the ovaries naturally declines so surgery would not be needed.)
    Biological therapy
    Biological therapy uses the body's natural ability (immune system) to fight cancer. Some women with metastatic breast cancer receive a biological therapy called Herceptin® (trastuzumab). It is a monoclonal antibody, a substance made in the laboratory that can bind to cancer cells.
    Herceptin is given to women whose lab tests show that a breast tumor has too much of a specific protein known as HER2. By blocking HER2, Herceptin can slow or stop the growth of the cancer cells.
    Herceptin is injected into a vein. It may be given by itself or along with chemotherapy. Like chemotherapy and hormonal therapy, it can affect cancer cells throughout the body.
    A woman may want to ask her doctor these questions before having systemic therapy (chemotherapy, hormonal therapy, or biological therapy):
    • Why do I need this treatment?
    • What drugs will I be taking? What will they do?
    • If I need hormonal treatment, would surgery to remove the ovaries or drugs be better for me?
    • When will treatment start? When will it end?
    • What are the expected benefits of the treatment? How will we know the treatment is working?
    • What are the risks and possible side effects of treatment? What can I do about them? Which side effects should I tell you about? Will there be long-term side effects?
    • Where will I go for treatment? Will I be able to drive home afterward? Will I need to stay in the hospital?
    • How will treatment affect my normal activities?
    • Would a clinical trial be appropriate for me?
    • What kind of follow-up care will I need?
    Treatment Choices by Stage
    A woman's treatment options depend on the stage of her disease and the following factors:
    • The size of the tumor in relation to the size of her breast
    • The results of lab tests (such as whether the breast cancer cells depend on hormones to grow)
    • Whether she has gone through menopause
    • Her general health
    The following are brief descriptions of treatments commonly used for each stage. (Other treatments may be appropriate for some women.) Clinical trials can be an option at all stages of breast cancer. See the The Promise of Cancer Research section for information about clinical trials.
    Stage 0
    Stage 0 breast cancer refers to lobular carcinoma in situ (LCIS) or ductal carcinoma in situ (DCIS):
    • LCIS: Most women with LCIS do not have treatment. Instead, the doctor may recommend regular checkups to look for signs of breast cancer. Some women take tamoxifen to reduce the risk of developing breast cancer. Others may take part in studies of promising new preventive treatments.
    • Having LCIS in one breast increases the risk of cancer for both breasts. For that reason, a very small number of women with LCIS decide to have surgery to remove both breasts (bilateral prophylactic mastectomy) to try to prevent cancer from developing. The surgeon usually does not remove the underarm lymph nodes.
    • DCIS: Most women with DCIS have breast-sparing surgery followed by radiation therapy. Some choose to have a total mastectomy. Underarm lymph nodes are not usually removed. Women with DCIS may receive tamoxifen to reduce the risk of developing invasive breast cancer.
    Stages I, II, and IIIA
    Women with Stage I, II, or IIIA breast cancer may have a combination of treatments. Some (especially those with Stage I or II breast cancer) choose breast-sparing surgery followed by radiation therapy to the breast. Others decide to have a mastectomy. With either approach, women (especially those with Stage II or IIIA breast cancer) often have lymph nodes under the arm removed. The doctor may suggest radiation therapy after mastectomy if cancer cells are found in more than three underarm lymph nodes, or if the tumor in the breast is large.
    The choice between breast-sparing surgery (followed by radiation therapy) and mastectomy depends on many factors:
    • The size, location, and stage of the tumor
    • The size of the woman's breast
    • Certain features of the cancer
    • How the woman feels about saving her breast
    • How the woman feels about radiation therapy
    • The woman's ability to travel to a radiation treatment center
    Some women (especially those with large Stage II or IIIA breast tumors) have chemotherapy before surgery. This treatment is called neoadjuvant therapy. Chemotherapy before surgery may shrink a large tumor so that breast-sparing surgery is possible.
    After surgery, many women receive adjuvant therapy (chemotherapy, hormonal therapy, or both). Adjuvant therapy is used to destroy any remaining cancer cells and prevent the cancer from coming back in the breast or elsewhere.
    Stages IIIB and IIIC
    Women with stage IIIB (including those with inflammatory breast cancer) or stage IIIC breast cancer usually have chemotherapy.
    If the chemotherapy shrinks the tumor, the doctor then may recommend additional treatment:
    • Mastectomy: The surgeon removes the breast and usually the lymph nodes under the arm. After surgery, the woman may receive radiation therapy to the chest and underarm area.
    • Breast-sparing surgery: The surgeon removes the cancer but not the breast. Usually, lymph nodes under the arm are removed. After surgery, the woman may receive radiation therapy to the breast and underarm area.
    • Radiation therapy instead of surgery: Some women have radiation therapy but no surgery.
    The doctor also may recommend additional chemotherapy, hormonal therapy, or both. Systemic therapy may help prevent the disease from coming back in the breast or elsewhere.
    Stage IV
    In most cases, women with stage IV breast cancer have hormonal therapy, chemotherapy, or both. Some also may have biological therapy. Radiation may be used to control tumors in certain parts of the body. These treatments are not likely to cure the disease, but they may help a woman live longer.
    Many women have palliative (supportive) care along with anticancer treatments intended to slow the progress of the disease. Some may receive only palliative care to manage their symptoms. Palliative care can help the woman feel better--physically and emotionally. The goal of this type of treatment is to control a woman's pain and other symptoms and to relieve the side effects of treatment (such as nausea), rather than to extend her life.
    Recurrent Breast Cancer
    Recurrent cancer is cancer that has come back after treatment. Treatment for the recurrent disease depends mainly on the location and extent of the cancer and on the type of treatment the woman had before.
    If breast cancer comes back in the breast (and not anywhere else) after breast-sparing surgery, the woman may have a mastectomy. Chances are good that the disease will not come back again elsewhere.
    If breast cancer recurs in other parts of the body, the treatment may involve chemotherapy, hormonal therapy, or biological therapy. Radiation therapy may help control cancer that recurs in the chest muscles or in certain other areas of the body.
    As with Stage IV breast cancer, treatment can seldom cure cancer that recurs outside the breast. Palliative care is often an important part of the treatment plan. Many patients have palliative care to ease their symptoms while they have anticancer treatments to slow the progress of the disease. Some receive only palliative care to improve their quality of life by easing pain, nausea, and other symptoms.
    Breast Cancer Clinical Trials
    Women with breast cancer may want to talk with their doctor about taking part in a clinical trial, a research study of new ways to treat cancer and prevent recurrence. Clinical trials are an important option for many women. Trials are available for all stages of breast cancer. Patients who join trials have the first chance to benefit from new treatments that have shown promise in earlier research. The Promise of Cancer Research section has more information about current treatment research. It tells how a woman or her doctor can find out about trials that may be appropriate for her.
    Side Effects of Cancer Treatment
    Because cancer treatment is likely to damage healthy cells and tissues, unwanted side effects are common. Specific side effects depend mainly on the type and extent of the treatment. Side effects may not be the same for each woman, or even for women having the same treatments. And a woman's side effects may change from one treatment session to the next. The health care provider will explain the possible side effects of treatment and how to manage them.
    The NCI provides helpful booklets about treatments and coping with side effects, such as Radiation Therapy and You, Chemotherapy and You, and Eating Hints for Cancer Patients. See the National Cancer Institute Information Resources and National Cancer Institute Booklets for other sources of information about side effects.
    Breast Cancer Surgery
    Surgery causes short-term pain and tenderness in the area of the operation. Before surgery, women may want to talk with their health care provider about pain management. Any kind of surgery also carries a risk of infection, bleeding, or other problems. Women who develop any problems should tell their health care provider right away.
    Removal of one or both breasts can cause a woman to feel off balance--especially if she has large breasts. This imbalance can cause discomfort in her neck and back. Also, the skin in the area where the breast was removed may feel tight. The muscles of the arm and shoulder may feel stiff and weak, but these problems usually are temporary. The doctor, nurse, or physical therapist can recommend exercises to help a woman regain movement and strength in her arm and shoulder.
    Because nerves may be injured or cut during surgery, a woman may have numbness and tingling in her chest, underarm, shoulder, and upper arm. These feelings usually go away within a few weeks or months, but for some women, numbness does not go away.
    Lymphedema
    Removing the lymph nodes under the arm slows the flow of lymph fluid. The fluid may build up in the arm and hand and cause swelling (lymphedema). This problem can develop right after surgery or months to years later. A woman needs to protect her arm and hand on the treated side for the rest of her life. She will need to:
    • Avoid wearing tight clothing or jewelry on her affected arm
    • Carry her purse or luggage with the other arm
    • Use an electric razor to avoid cuts when shaving her underarm
    • Have shots, blood tests, and blood pressure measurements on the other arm
    • Wear gloves to protect her hands when gardening and when using strong detergents
    • Have careful manicures and avoid cutting her cuticles
    • Avoid burns or sunburns to her affected arm and hand
    A woman should ask her doctor how to handle any cuts, insect bites, sunburn, or other injuries to the arm or hand. Also, she should contact the doctor if that arm or hand is injured, swells, or becomes red and warm.
    If lymphedema occurs, the doctor may suggest exercises and other ways to deal with this problem. For example, some women with lymphedema wear an elastic sleeve to improve lymph circulation. The doctor also may suggest other approaches, such as medication, manual lymph drainage (massage), or use of a machine that gently compresses the arm. The woman may be referred to a physical therapist or another specialist.
    More information about lymphedema is available on NCI's Web site at http://cancer.gov and from NCI's Cancer Information Service at 1-800-4-CANCER.
    Radiation Therapy
    During radiation therapy, women with breast cancer may become tired, especially toward the end of treatment. This feeling may continue for a while after treatment is over. Resting is important, but doctors usually advise patients to try to stay as active as they can.
    It is also common for the skin in the treated area to become red, dry, tender, and itchy. The breast may feel heavy and tight. These problems will go away over time. Toward the end of treatment, the skin may become moist and "weepy." Exposing this area to air as much as possible can help the skin heal.
    Because bras and some other types of clothing may rub the skin and cause irritation, women may want to wear loose-fitting cotton clothes during this time. Gentle skin care also is important, and women should check with their doctor before using any deodorants, lotions, or creams on the treated area. These effects of radiation therapy on the skin are temporary, and the area gradually heals once treatment is over. However, there may be a lasting change in the color of the skin.
    Chemotherapy
    As with radiation, chemotherapy affects normal cells as well as cancer cells. The side effects of chemotherapy depend mainly on the specific drugs and the dose. In general, anticancer drugs affect cells that divide rapidly, especially:
    • Blood cells: These cells fight infection, help the blood to clot, and carry oxygen to all parts of the body. When blood cells are affected, patients are more likely to get infections, may bruise or bleed easily, and may feel very weak and tired.
    • Cells in hair roots: Chemotherapy can lead to hair loss. The hair grows back, but the new hair may be somewhat different in color and texture.
    • Cells that line the digestive tract: Chemotherapy can cause poor appetite, nausea and vomiting, diarrhea, or mouth and lip sores. Many of these side effects can be controlled with drugs.
    Some anticancer drugs can damage the ovaries. If the damaged ovaries stop making hormones, the woman may have symptoms of menopause, such as hot flashes and vaginal dryness. Her menstrual periods may become irregular or may stop, and she may become infertile (unable to become pregnant). For women over the age of 35, infertility is likely to be permanent.
    On the other hand, if a woman remains fertile during chemotherapy, she may be able to become pregnant. Because the effects of chemotherapy on an unborn child are not known, a woman may wish to talk with her doctor about birth control before treatment begins.
    Although long-term side effects are quite rare, there have been cases in which the heart becomes weakened. Also, second cancers, such as leukemia (cancer of the blood cells), have occurred in people who have had chemotherapy.
    Hormonal Therapy
    The side effects of hormonal therapy depend largely on the specific drug or type of treatment. Tamoxifen is the most common hormonal treatment. It blocks the effects of estrogen on cells. Not all women who take tamoxifen have side effects. In general, the side effects of tamoxifen are similar to some of the symptoms of menopause. The most common side effects are hot flashes and vaginal discharge. Some women experience irregular menstrual periods, headaches, fatigue, nausea and/or vomiting, vaginal dryness or itching, irritation of the skin around the vagina, and skin rash.
    Women who are still menstruating may become pregnant when taking tamoxifen. Tamoxifen may harm the unborn baby. Women should discuss birth control methods with their doctor before taking tamoxifen.
    Serious side effects of tamoxifen are rare. However, it can cause blood clots in the veins, especially in the legs and in the lungs. In a small number of women, tamoxifen can slightly increase the risk of stroke. Also, it can cause cancer that arises in the lining or the muscular wall of the uterus. Any unusual vaginal bleeding should be reported to the doctor. The doctor may do a pelvic exam, as well as a biopsy of the lining of the uterus, or other tests.
    If the hormonal therapy is surgery to remove the ovaries, a woman will go through menopause immediately. The side effects are likely to be more severe than problems associated with natural menopause. The health care provider can suggest ways to cope with these side effects.
    Biological Therapy
    Herceptin is the biological therapy used to treat some women with breast cancer that has spread. Side effects that most commonly occur during the first treatment with Herceptin are fever and chills. Other possible side effects include pain, weakness, nausea, vomiting, diarrhea, headaches, difficulty breathing, and rashes. These side effects generally become less severe after the first treatment.
    Herceptin also may cause heart damage, which may lead to heart failure. It can also affect the lungs, causing breathing problems that require immediate medical attention. Before a woman receives Herceptin, the health care provider checks the woman for heart and lung problems. During treatment, the health care provider watches for signs of heart and lung problems.
    [Top]
    Complementary and Alternative Medicine
    Some women with breast cancer use complementary and alternative medicine healing approaches to reduce stress or to reduce side effects and symptoms:
    • An approach is generally called complementary medicine when it is used in addition to treatments prescribed by a doctor.
    • An approach is called alternative medicine when it is used instead of a standard treatment.
    Some common types of complementary and alternative medicine are acupressure, acupuncture, massage therapy, herbal products, vitamins or special diets, visualization, meditation, and spiritual healing. Many women report that such approaches help them feel better.
    However, some types of complementary and alternative medicine may interfere with or may be harmful when used with treatments prescribed by a doctor. Before trying any of these therapies, a woman should discuss their possible benefits and risks with her doctor.
    Breast Reconstruction
    Some women who need a mastectomy decide to have breast reconstruction, either at the same time as the mastectomy or later on. Other women prefer to wear a breast form (prosthesis). Still others decide to do nothing. All of these options have pros and cons, and what is right for one woman may not be right for another. What is important is that nearly every woman treated for breast cancer has choices. A woman considering breast reconstruction should consult with a plastic surgeon before the mastectomy, even if the reconstruction would be done later on.
    Various procedures are used to reconstruct the breast. Some women choose to have implants (either saline or silicone). The safety of silicone breast implants has been under review by the Food and Drug Administration (FDA) for several years. Women interested in having silicone implants should talk with their doctor about the FDA's findings and the availability of silicone implants.
    A woman also may have breast reconstruction with tissue that is moved from another part of her body. Skin, muscle, and fat can be moved to the chest from the lower abdomen, back, or buttocks. The plastic surgeon uses this tissue to create a breast shape.
    Which type of reconstruction is best depends on a woman's age, body type, and the type of surgery she had. The plastic surgeon can explain the risks and benefits of each type of reconstruction.
    A woman may want to ask her doctor these questions about breast reconstruction:
    • What is the latest information about the safety of silicone breast implants?
    • Which type of surgery would give me the best results? How will I look afterward?
    • When can breast reconstruction begin?
    • How many surgeries will I need?
    • What are the risks at the time of surgery? Later?
    • Will there be scars? Where? What will they look like?
    • If skin, muscle, and fat from another part of my body is used, will there be any permanent changes where tissue was removed?
    • What activities should I avoid? When can I return to my normal activities?
    • Will I need follow-up care?
    • How much will reconstruction cost? Will my health insurance pay for it?
    The Cancer Information Service at 1-800-4-CANCER can suggest other sources of information about breast reconstruction.
    Recovery from Breast Cancer
    Health care providers make every effort to help women with breast cancer return to their normal activities as soon as possible. Recovery is different for each woman, depending on the type of treatment, whether the disease has spread, and other factors.
    Exercising the arm and shoulder after surgery can help a woman regain motion and strength in these areas. It can also reduce pain and stiffness in her neck and back. Special exercises can begin as soon as the doctor says the woman is ready, often within a day or so after surgery. Exercising begins slowly and gently and can even be done in bed. It is often done under the direction of a physical therapist. Over time, exercising can be more active. Regular exercise can then become part of a woman's normal routine. (Women who have a mastectomy and immediate breast reconstruction need special exercises, which the health care provider will explain.)
    Often, performing certain exercises and resting with the arm propped up on a pillow can prevent or reduce lymphedema after surgery. Information about lymphedema prevention and treatment is in the Side Effects section.
    More information about recovery can be found in the NCI's booklet Facing Forward Series: Life After Cancer Treatment.
    Follow-up Care
    Regular checkups are important after breast cancer treatment. Even when the cancer seems to have been completely removed or destroyed, the disease sometimes returns because undetected cancer cells remained somewhere in the body after treatment. The health care provider monitors recovery and checks for recurrence of cancer. Checkups help ensure that any changes in health are noted.
    A woman who has had cancer in one breast should report any changes in the treated area or in the other breast to her doctor right away. A woman should also report if she has any physical problems, such as pain, loss of appetite or weight, changes in menstrual cycles, unusual vaginal bleeding, or blurred vision. She should also report headaches, dizziness, shortness of breath, coughing or hoarseness, backaches, or digestive problems that seem unusual or that don't go away. Some problems may arise months or years after treatment. They may suggest that the cancer has returned, but they can also be symptoms of many other health problems. It is important to share these concerns with a health care provider so problems can be diagnosed and treated as soon as possible.
    Follow-up usually includes examination of the breasts, chest, neck, and underarm areas. Because a woman who has had breast cancer is at risk of getting cancer again, she should have mammograms of the preserved breast and/or opposite breast. However, a woman usually does not need a mammogram of the reconstructed breast. Sometimes the doctor may order other imaging procedures or lab tests.
    The NCI has prepared a booklet for people who have completed their treatment to help answer questions about follow-up care and other concerns. Facing Forward Series: Life After Cancer Treatment provides tips for making the best use of medical visits. It describes how to talk to the doctor about creating a plan of action for recovery and future health.
    SUPPORT FOR WOMEN WITH BREAST CANCER
    A diagnosis of breast cancer can change a woman's life and the lives of those close to her. These changes can be hard to handle. It is common for the woman and her family and friends to have many different and sometimes confusing emotions. Many women find that having good information and support services can make it easier to cope.
    People living with cancer may worry about caring for their families, keeping their jobs, or continuing daily activities. Concerns about tests, treatments, hospital stays, and medical bills are also common. The health care provider can answer questions about treatment, working, or other activities. Meeting with a social worker, counselor, or member of the clergy can be helpful to those who want to talk about their feelings or discuss their concerns. Often, a social worker can suggest resources for help with recovery, emotional support, financial aid, transportation, or home care.
    Friends and relatives can be very supportive. Also, many women find it helps to discuss their concerns with others who have cancer. Women with breast cancer often get together in support groups, where they can share what they have learned about coping with their disease and the effects of their treatment. It is important to keep in mind, however, that each woman is different. Ways that one woman deals with cancer may not be right for another. A woman may want to ask her health care provider about advice she receives from other breast cancer survivors.
    Several organizations offer special programs for women with breast cancer. Trained volunteers, who have had breast cancer themselves, may talk with or visit women with breast cancer, provide information, and lend emotional support. They often share their experiences with breast cancer treatment, rehabilitation, and breast reconstruction.
    Sometimes women who have had breast cancer are afraid that changes to their body will affect not only how they look but also how other people feel about them. They may be concerned that breast cancer and its treatment will affect their sexual relationships. Many couples find it helps to talk about their concerns. Some find that counseling or a couples' support group can be helpful.
    The Cancer Information Service (1-800-4-CANCER) can provide printed materials on coping with cancer, as well as information to help women with breast cancer and their families locate programs, services, and publications.
    The Promise of Breast Cancer Rresearch
    Research has led to important advances in breast cancer. Doctors all over the country are conducting many types of clinical trials (research studies in which people volunteer to take part). These are studies of new ways to prevent, detect, diagnose, and treat breast cancer. Researchers are also studying the psychological effects of the disease and ways to improve a patient's comfort and quality of life.
    Clinical trials are designed to answer important questions and to find out whether the new approach is safe and effective. Often, clinical trials compare a new method with a widely accepted approach.
    People who join clinical trials have the first chance to benefit from new approaches. They also make an important contribution to medicine by helping doctors learn more about the disease. Although clinical trials may pose some risks, researchers take many steps to protect their patients.
    Women who are interested in being part of a clinical trial should talk with their doctor. They may want to read the NCI booklets Taking Part in Clinical Trials: What Cancer Patients Need To Know or Taking Part in Clinical Trials: Cancer Prevention Studies. The NCI also offers an easy-to-read brochure called If You Have Cancer…What You Should Know About Clinical Trials. These NCI publications describe how clinical trials are carried out and explain their possible benefits and risks.
    NCI's Web site includes a section on clinical trials at http://cancer.gov/clinical_trials with general information about clinical trials as well as detailed information about specific ongoing studies of breast cancer. The Cancer Information Service at 1-800-4-CANCER or LiveHelp at http://cancer.gov can answer questions and provide information about clinical trials. Another source of information is the NCI's Cancer Trials Support Unit (CTSU), which enables many more doctors and their patients to take part in large clinical trials. Patients can learn more about the trials at http://www.ctsu.org.
     
    Research on Causes
    The main known risk factors for breast cancer are listed in the Breast Cancer: Who's at Risk? section. Scientists are trying to learn more about other factors that may increase the risk of breast cancer, including:
    • Diet: Some evidence suggests a link between diet and breast cancer. Women whose diets are rich in fruits and vegetables have a lower risk of getting breast cancer. Women whose diets are low in fat also seem to have a lower risk. More research is needed to better understand the types and amounts of fat that raise cancer risk. Researchers also are studying dietary supplements that may reduce the risk of breast cancer.
    • Hormonal factors: In addition to the reproductive and menstrual history risk factors described earlier, other hormonal factors are under study. Scientists are studying how hormones, in general and during pregnancy, influence the development of breast cancer.
    • Environmental factors: Researchers are studying whether certain substances in the environment can increase the risk of breast cancer.
    • Not enough exercise: Scientists continue to study the effect of physical activity on the risk of breast cancer.
    Research on Prevention
    Scientists are looking for drugs that may prevent breast cancer. In one large study, the drug tamoxifen reduced the number of new cases of breast cancer among women who were at an increased risk of the disease. Doctors are now studying whether the drug raloxifene is as effective as tamoxifen. This study is called STAR (Study of Tamoxifen and Raloxifene). STAR includes women who are over age 35, have gone through menopause, and are at increased risk of the disease.
    Research on Detection and Diagnosis
    At this time, mammograms are the most effective tool we have to detect changes in the breast that may be cancer. A very large study is comparing the accuracy of standard mammography to that of digital mammography, which uses a computer (rather than x-ray film) to store the image of the breast. The images are displayed on a computer monitor and can be enhanced (lightened or darkened). Because the images can be adjusted, the doctor may be better able to detect abnormal tissue.
    Researchers are also exploring other techniques, such as magnetic resonance imaging (MRI) and positron emission tomography (PET), to produce detailed pictures of the tissues in the breast.
    In addition, researchers are studying tumor markers. These are substances that may be present in abnormal amounts in people with cancer. Tumor markers may be found in blood or urine, or in fluid from the breast (nipple aspirate). Some markers may be used with breast cancer patients to check for signs of disease after treatment. At this time, however, no tumor marker test is reliable enough to be used routinely to detect breast cancer.
    Ductal lavage also is under study. This technique collects samples of cells from breast ducts. A catheter (a very thin, flexible tube) is inserted into the opening of a milk duct on the surface of the nipple. A salt water solution is put into the milk duct through the catheter. When the solution is withdrawn, it contains cells from inside the ducts. These cells are checked under a microscope to look for breast cancer or changes that may suggest an increased risk of cancer.
     
    Research on Breast Cancer Treatment
    Researchers are studying surgery, radiation therapy, chemotherapy, hormonal therapy, biological therapy, and combinations of these types of treatment.
    • Surgery: Different types of surgery are being combined with other treatments.
    • Radiation therapy: Doctors are testing treatment with and without radiation therapy.
    • Chemotherapy: Researchers are testing new anticancer drugs and doses. They are working with various drugs and drug combinations. They also are looking at ways of combining drugs before surgery and at new ways of combining chemotherapy with hormonal therapy or radiation therapy.
    • Hormonal therapy: Researchers are testing several types of hormonal therapy, including aromatase inhibitors.
    • Biological therapy: New biological approaches also are under study. For example, researchers are studying cancer vaccines that help the immune system kill cancer cells.
    In addition, researchers are exploring ways to lessen the side effects of treatment (such as lymphedema from surgery), reduce pain, and improve the quality of patients' lives. One procedure under study is called sentinel lymph node biopsy. Researchers want to know whether this procedure can reduce the number of lymph nodes that are removed during surgery. First, a radioactive substance and a blue dye are injected into tissue near the tumor. These substances flow through the lymphatic system to the first lymph node or nodes where cancer cells are likely to have spread (the "sentinel" node or nodes). To find the sentinel node, the surgeon looks for the dye and uses a scanner to locate the radioactive substance. The surgeon removes only the node or nodes containing the radioactive substance or blue dye. A pathologist checks the sentinel lymph nodes for cancer cells. If sentinel lymph node biopsy proves to be as effective as the standard axillary lymph node dissection, the new procedure could reduce the chance of developing lymphedema.
