Breast cancer is cancer that starts in the breast and is the most common cancer in women. There are two main types of invasive breast cancer: (1) ductal carcinoma and (2) lobular carcinoma.
Invasive ductal carcinoma, the most common type, starts in the ducts, or tubes, that move milk from the breast to the nipple. Invasive Lobular carcinoma starts in the part of the breast that produces milk, called lobules.
Over the course of a lifetime, 1 in 8 women will develop breast cancer.
