Chemotherapy Treatment for Breast Cancer

In cancer treatment, chemotherapy refers to the use of drugs to kill or slow the growth of rapidly multiplying cells.

Chemotherapy usually includes a combination of drugs, since this is more effective than a single drug given alone. There are many drug combinations used to treat breast cancer. Ask your doctor for specific information and side effects you can expect from your chemotherapy medications.

How Is Chemotherapy Given?

Chemotherapy drugs are given intravenously (directly into a vein) or orally (by mouth). Once the drugs enter the bloodstream, they travel to all parts of the body in order to reach cancer cells that may have spread beyond the breast -- therefore chemotherapy is considered a "systemic" form of breast cancer treatment.

Chemotherapy is given in cycles of treatment followed by a recovery period. The entire chemotherapy treatment generally lasts three to six months, depending on the type of drugs given.

Chemotherapy Treatment for Breast Cancer

What is male breast cancer?

Men possess a small amount of nonfunctioning breast tissue (breast tissue that cannot produce milk) that is concentrated in the area directly behind the nipple on the chest wall. Like breast cancer in women, cancer of the male breast is the uncontrolled growth of the cells of this breast tissue.

Breast tissue in both young boys and girls consists of tubular structures known as ducts. At puberty, a girl's ovaries produce female hormones (estrogen) that cause the ducts to grow and milk glands (lobules) to develop at the ends of the ducts. The amount of fat and connective tissue in the breast also increases as girls reach puberty. On the other hand, male hormones (such as testosterone) secreted by the testes suppress the growth of breast tissue and the development of lobules. The male breast, therefore, is made up of predominantly small, undeveloped ducts and a small amount of fat and connective tissue....
