Breast cancer occurs when cells within the breast begin to grow abnormally, dividing more rapidly than healthy cells and accumulate to form a lump or mass. These cells may spread — or metastasize — through the breast to lymph nodes or other areas of the body.
Breast cancer is the second-most common cancer diagnosed in women in the U.S. While breast cancer can occur in both men and women, it is far more common in women. Hormonal, lifestyle, and environmental factors may increase the risk of developing breast cancer. By raising awareness and research funding, survival rates have also risen, through various diagnostic and treatment options.
