Breast cancer is a disease that occurs when cells in the breast tissue begin to grow uncontrollably.2 It often starts in the milk-producing glands or the ducts that carry milk to the nipple. While breast cancer most commonly affects women, men can also develop the disease.3
Cancerous cells may form tumors or lumps in one or both breasts, though not all breast lumps are cancerous. Even so, it’s important to ask your doctor to evaluate any lumps, changes or abnormalities.
Breast cancer can start when abnormal cells in the breast multiply and form a tumor. Some tumors are benign, which means they aren’t cancerous. Malignant tumors, however, are cancerous and may grow into nearby tissue or spread to other parts of the body.
Breast cancer may begin in different parts of the breast, such as the ducts, lobules or surrounding tissue.
Breast cancer can spread when cancer cells move beyond the original tumor. They may spread to nearby lymph nodes first.
If cancer cells enter the blood or lymphatic system, they can travel to other parts of the body, such as the bones, lungs, liver or brain. Breast cancer that spreads to other areas of the body is called metastatic breast cancer.4
