Some Breast Cancer Basics Breast cancer, a common cancer in women, is a disease in which cancer (malignant) cells are found in the tissues of the breast. Each breast has 15 to 20 sections called lobes, which have many smaller sections called lobules. The lobes and lobules are connected by thin tubes called ducts. The most common type of breast cancer is ductal cancer. It is found in the cells of the ducts. Cancer that begins in the lobes or lobules is called lobular cancer. Lobular cancer is more often found in both breasts than other types of breast cancer. Inflammatory breast cancer is an uncommon type of breast cancer. In this disease, the breast is warm, red, and swollen.Hereditary breast cancer makes up approximately 5% to 10% of all breast cancer cases. The genes in cells carry the hereditary information that is received from a person's parents. Several genes have been found to be defective in some breast cancer patients. Relatives of breast cancer patients who carry these defective genes may be more likely to develop breast or ovarian cancer. Some defective genes are more common in certain ethnic groups. Tests are being developed to determine who has the genetic defect long before any cancer appears. Hormonal contraceptives may be another factor to consider. Research findings suggest a link between contraceptive use and a slightly increased risk of developing breast cancer. A doctor should be seen if changes in the breasts are noticed. The doctor may suggest that you have a mammogram. A mammogram is a special x-ray of the breast that may find tumors that are too small to feel. If a lump in the breast is found, the doctor may need to cut out a small piece of the lump and look at it under the microscope to see if there are any cancer cells. This procedure is called a biopsy. Sometimes the biopsy is done by inserting a needle into the breast and drawing out some of the tissue. If the biopsy shows that there is cancer, it is important that certain tests (called estrogen and progesterone receptor tests) be done on the cancer cells. Estrogen and progesterone receptor tests may tell whether hormones affect the way the cancer grows. They may also give information about the chances of the tumor coming back (recurring). The results help a doctor decide whether to use hormone therapy to stop the cancer from growing. Tissue from the tumor needs to be taken to the laboratory for estrogen and progesterone tests at the time of biopsy because it may be hard to get enough cancer cells later, although newer techniques can be used on tissue that is not fresh. The chance of recovery (prognosis) and choice of treatment depend on the stage of the cancer (whether it is just in the breast or has spread to other places in the body), the type of breast cancer, certain characteristics of the cancer cells, and whether the cancer is found in the other breast. A woman's age, weight, menopausal status (whether or not a woman is still having menstrual periods), and general health can also affect the prognosis and choice of treatment. If a patient is going to have a mastectomy, breast reconstruction (making a new breast mound) may be considered. It may be done at the time of the mastectomy or at some future time. The breast may be made with the patient's own (non-breast) tissue or by using implants. Different types of implants can be used. The Food and Drug Administration (FDA) has announced that breast implants filled with silicone gel may only be used in clinical trials. Saline-filled breast implants, which contain saltwater rather than silicone gel, may also be used. Additional questions can then be discussed with a doctor.
