The American Cancer Society estimates that in 2009 about 1,910 new cases of invasive breast cancer will be diagnosed among men in the United States. Breast cancer is about 100 times less common among men than among women. 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. In 2009, about 440 men will die from breast cancer in the United States.

Signs and symptoms of breast cancer in men include: nipple discharge (usually bloody), nipple inversion, breast lump, and occasionally, local pain, itching and pulling sensation.

The survival rate of men and women is comparable by stage of disease at the time of diagnosis. However, men are usually diagnosed at a later stage because they are less likely to report any symptoms.

Treatment of male breast cancer is the same as treatment for female patients and usually includes a combination of surgery, radiation, chemotherapy, and/or hormone therapy.
