Treatment – Breast cancer

Treatment is based on many factors, including type and stage of the cancer, whether the cancer is sensitive to certain hormones, and whether or not the cancer overproduces (overexpresses) a gene called HER2/neu.

In general, cancer treatments may include:

• Chemotherapy medicines to kill cancer cells
• Radiation therapy to destroy cancerous tissue
• Surgery to remove cancerous tissue -- a lumpectomy removes the breast lump; mastectomy removes all or part of the breast and possible nearby structures

Other treatments:

• Hormonal therapy to block certain hormones that fuel cancer growth
• Targeted therapy to interfere with cancer cell grow and function

An example of hormonal therapy is the drug tamoxifen. This drug blocks the effects of estrogen, which can help breast cancer cells survive and grow. Most women with estrogen sensitive breast cancer benefit from this drug. A newer class of medicines called aromatase inhibitors, such as exemestane (Aromasin), have been shown to work just as well or even better than tamoxifen in post-menopausal women with breast cancer.

Targeted therapy, also called biologic therapy, is a newer type of cancer treatment. This therapy uses special anti-cancer drugs that identify certain changes in a cell that can lead to cancer. One such drug is trastuzumab (Herceptin). For women with stage IV HER2-positive breast cancer, Herceptin plus chemotherapy has been shown to be work better than chemotherapy alone. Studies have also shown that in women with early stage HER2-positive breast cancer, this medicine plus chemotherapy cuts the risk of the cancer coming back by 50%.

Cancer treatment may be local or systemic.

• Local treatments involve only the area of disease. Radiation and surgery are forms of local treatment.
• Systemic treatments affect the entire body. Chemotherapy is a type of systemic treatment.

Most women receive a combination of treatments. For women with stage I, II, or III breast cancer, the main goal is to treat the cancer and prevent it from returning. For women with stage IV cancer, the goal is to improve symptoms and help them live longer. In most cases, stage IV breast cancer cannot be cured.

• Stage 0 and DCIS -- Lumpectomy plus radiation or mastectomy is the standard treatment. There is some controversy on how best to treat DCIS.
• Stage I and II -- Lumpectomy plus radiation or mastectomy with some sort of lymph node removal is standard treatment. Hormone therapy, chemotherapy, and biologic therapy may also be recommended following surgery.
• Stage III -- Treatment involves surgery possibly followed by chemotherapy, hormone therapy, and biologic therapy.
• Stage IV -- Treatment may involve surgery, radiation, chemotherapy, hormonal therapy, or a combination of such treatments.

After treatment, some women will continue to medicaiotns such as tamoxifen for a period of time. All women will continue to have blood tests, mammograms, and other tests following treatment.

Symptoms - Breast cancer

Early breast cancer usually does not cause symptoms. This is why regular breast exams are important. As the cancer grows, symptoms may include:

• Breast lump or lump in the armpit that is hard, has uneven edges, and usually does not hurt
• Change in the size, shape, or feel of the breast or nipple -- for example, you may have redness, dimpling, or puckering that looks like the skin of an orange
• Fluid coming from the nipple -- may be bloody, clear-to-yellow, or green, and look like pus

Men get breast cancer, too. Symptoms include breast lump and breast pain and tenderness.

Symptoms of advanced breast cancer may include:

• Bone pain
• Breast pain or discomfort
• Skin ulcers
• Swelling of one arm (next to breast with cancer)
• Weight loss

Overview Breast cancer

Breast cancer is a cancer that starts in the tissues of the breast.

There are two main types of breast cancer:

• Ductal carcinoma starts in the tubes (ducts) that move milk from the breast to the nipple. Most breast cancers are of this type.
• Lobular carcinoma starts in parts of the breast, called lobules, that produce milk.

In rare cases, breast cancer can start in other areas of the breast.

Many breast cancers are sensitive to the hormone estrogen. This means that estrogen causes the breast cancer tumor to grow. Such cancer is called estrogen receptor positive cancer or ER positive cancer.

Some women have what's called HER2-positive breast cancer. HER2 refers to a gene that helps cells grow, divide, and repair themselves. When cells have too many copies of this gene, cells -- including cancer cells -- grow faster. Experts think that women with HER2-positive breast cancer have a more aggressive disease and a higher risk of recurrence than those who do not have this type.

Clinical trials - Breast Cancer Treatment

Clinical trials are studies that people try to accept the new treatment. (Under caution) to help doctors identify the best treatment with minimal side effects. These studies help improve the overall quality of care.

Today less than 5% of patients with breast cancer treated in clinical trials. Why? One factor is about the trials and how the application of the tests often do not understand. In this section you can find information about things related to clinical trials and participation in one.
