Breast Cancer

There are several types of breast cancer, but most are invasive ductal carcinomas. These originate in the milk ducts before spreading to other parts of the breast. Other types of breast cancer include ductal carcinoma in situ (DCIS), which originates in milk ducts but has not yet spread; and invasive lobular carcinoma, which starts in milk-producing glands. Symptoms of breast cancer can include: the presence of a lump, swelling of all or part of a breast, skin irritation or dimpling, breast or nipple pain, nipple retraction, redness, and nipple discharge other than breast milk. Breast cancer is often treated with a combination of surgery, radiation therapy, hormone therapy, and/or chemotherapy. The survival rate for breast cancer varies depending on the stage of diagnosis, type of treatment, and other factors.
