Breast cancer is cancer that forms in tissues of the breast, usually the ducts (tubes that carry milk to the nipple) and lobules (glands that make milk).

Definition from the American Cancer Society:

Breast cancer is a malignant tumor that starts from cells of the breast. A malignant tumor is a group of cancer cells that may invade surrounding tissues or spread (metastasize) to distant areas of the body. The disease occurs almost entirely in women, but men can get it, too.

Answer 3

Breast cancer is the development of abnormal cells in the breast. They begin to grow out of control and produce more cells that grow into tumors, or growths. When breast cancer expands, cancer cells are frequently formed in the underarm lymph nodes (axillary lymph nodes). Breast cancer cells can expand from the breast to nearly any other part of the body, like the lungs, bones, liver, or brain.
