The female breast is made up of many glands called lobules. Lobules produce milk that is sent to the nipple through small tubes called ducts. Many breast cancer tumors begin in the cells that line these ducts. Other tumors start in cells lining the lobules. These are known as ductal cancer and lobular cancer, respectively.
Breast cancer is the most common type of cancer among women, except for skin cancers. In 2012, almost 230,000 new cases of breast cancer are expected to be diagnosed in the United States. It is the second-leading cause of cancer death in women after lung cancer. Breast cancer also affects men, but at a much lower rate. Nearly 2,200 new cases of breast cancer are expected to be diagnosed in men in 2012.
Most masses found in the breast are benign. This means they are not cancerous, or malignant. Benign masses in the breast do not spread to nearby tissues or to other parts of the body. But they may grow in size. Malignant tumors are cancers and can spread to other parts of the body.
The type of treatment you will get depends on many factors, including the type and stage of your tumor. Breast cancer can be treated with surgery, chemotherapy, hormone therapy, radiation therapy, and targeted therapy. Your doctor will discuss which treatment is right for you.
Chemotherapy Can Cause Side Effects
Chemotherapy stops or slows the growth of cancer cells. Often, cancer cells are fast growing. But chemo also damages healthy cells that divide quickly. These healthy cells can include cells in the bone marrow that make blood, cells in the lining of the gut and mouth, and hair cells. Damage to healthy cells is what causes many chemo side effects. Here's how it works:
- When chemo damages healthy blood cells, the result can be :
- Chemo may damage healthy cells in the stomach. The chemo drugs then irritate these areas, which could result in nausea and vomiting. Chemotherapy drugs may also trigger signals in the brain that tell your body to vomit.
- When chemo affects healthy cells surrounding hair follicles, the result can be hair loss. Hair loss is also known as alopecia.
