The American Cancer Society estimates that in 2008 some 1,990 new cases of invasive breast cancer will be diagnosed among men and about 450 men will die from breast cancer in the United States. Breast cancer is about 100 times less common among men than among women and accounts for less than half of 1% of cancer deaths among men. For men, the lifetime risk of getting breast cancer is about 1/10th of 1% (1 in 1,000). The number of breast cancer cases in men relative to the population has been fairly stable over the last 30 years.
