Breast cancer is cancer that starts in the breast. It is one of the most common types of cancer found in American women, and occurs very rarely in men. Women with breast cancer are also at higher risk for ovarian cancer. Fortunately, thanks to advancements in early detection and treatment, many women survive a breast cancer diagnosis.
According to the American Cancer Society, in 2011, 230,480 new cases of invasive breast cancer will be diagnosed among women, as well as an estimated 57,650 additional cases of in situ breast cancer. In 2011, approximately 39,520 women are expected to die from breast cancer.
