A Guide to the Stages of Breast Cancer
Breast cancer is a disease in which the breast cells grow uncontrollably. There are different types of breast cancer based on the breast cells that turn malignant. Breasts are made of three main parts—connective tissues, ducts, and lobules. Lobules are the mammary glands that produce milk, and the connective tissue is made of fibrous and fatty tissues that hold the breast together.
