Cancer occurs when changes called mutations take place in genes that regulate cell growth. The mutations let the cells divide and multiply in an uncontrolled way. Breast cancer is cancer that develops in breast cells. Typically, the cancer forms in either the lobules or the ducts of the breast.

Breast cancer is a common cancer, with more than , individuals diagnosed in the United States each year. The normal breast has 6 to 9 overlapping sections called lobes and within each lobe are several smaller lobules that contain the cells that produce milk. The lobes and lobules are linked by thin tubes called ducts, which lead to the nipple in the center of the breast. The spaces around the lobules and ducts are filled with fat. Lymph vessels carry colorless fluid called lymph, which contains important immune cells. The lymph vessels lead to small bean-shaped structures called lymph nodes. Clusters of lymph nodes are found in the axilla under the arm , above the collarbone, and in the chest.
