There are about 182,000 cases of new breast cancer each year in the United States.
Breast cancer is the most common type of cancer among women in the United States.
8 out of 10 breast lumps are not cancerous. When breast cancer is found and treated early, a woman has more treatment choices and a chance of complete recovery. The breast, like all parts of the body, is made of cells. A cell is the smallest building block of the body. Healthy cells grow and divide in an orderly way.
