Breast cancer is a group of cancer cells (malignant tumor) that starts in the cells of the breast and invades surrounding tissues or spreads (metastasizes) to other areas of the body. As in all forms of cancer, breast cancer is made of abnormal cells that have grown uncontrollably. Those cells may also travel to places in your body where they aren’t normally found. When that happens, the cancer is called metastatic.
Breast cancer usually begins in a small, confined area in the glands, which produce milk (lobular carcinoma) or the ducts (ductal carcinoma), which carry it to the nipple. It can grow larger in the breast and spread through channels to nearby lymph nodes or through your bloodstream to other organs. Cancer may grow and invade tissue around the breast, such as the skin or chest wall. Different types of breast cancer grow and spread at different rates — some take years to spread beyond the breast, while others grow and spread quickly.
