In the United States, there were 216,000 cases of invasive breast cancer and 40,000 deaths in 2004.[2] Worldwide, breast cancer is the second most common type of cancer after lung cancer (10.4% of all cancer incidence, both sexes counted)[3] and the fifth most common cause of cancer death.[4] In 2004, breast cancer caused 519,000 deaths worldwide (7% of cancer deaths; almost 1% of all deaths).[4]
Breast cancer is about 100 times as frequent among women as among men, but survival rates are equal in both sexes.
