Breast Cancer in Men Fact Sheet No. 43
Warren, Barbour S.; Devine, Carol
Breast cancer is a rare disease among men. Many of the risk factors for male breast cancer are the same or similar to the risk factors for breast cancer in women. The survival of men with breast cancer is lower than survival in women but this results from death due to other health problems rather than breast cancer itself.
