Surgery is standard. For smaller tumors, you might get a breast conserving surgery, or lumpectomy, in which only the tumor and some of the tissue around it are removed. For larger tumors, you might need a mastectomy, in which the breast is removed. In either case, the surgeon will likely remove some of the lymph nodes. After a mastectomy, you might choose breast reconstruction surgery.
Radiation therapy usually follows a lumpectomy. It can kill cancer cells that were missed during surgery. Some women who get a mastectomy will also have radiation, especially if the tumor was large or there were cancer cells in the lymph nodes.
Chemotherapyafter surgery can help destroy remaining cancer cells that were missed. Some people have chemotherapy before surgery to try to shrink a tumor. If it works, the tumor might then be small enough to remove with a lumpectomy.
You can get chemo several different ways. You may take pills or liquids, but often the drugs are put right into your veins. Depending on the type of treatment, it may be given in cycles that allow your body breaks in between.
Hormone therapy after surgery may help women who have hormone receptor-positive cancer. That means the cancer needs hormones to grow. Medicines can prevent the tumor from getting the hormones. These drugs include tamoxifen for all women, and anastrozole (Arimidex), exemestane (Aromasin), and letrozole (Femara) for postmenopausal women.
Women who haven't reached menopause may consider having their ovaries removed to stop them from making hormones that help cancer grow. They also can take a drug, such as leuprolide (Lupron) or goserelin (Zoladex), to stop their ovaries from releasing hormones.
