Although male breast cancer is rarely discussed, it is not exceedingly rare. On average, for every hundred females diagnosed with breast cancer, there will be one male diagnosed with breast cancer. Approximately 2,000 cases of male breast cancer are diagnosed yearly in the USA, compared to approximately 200,000 cases of female breast cancer diagnosed per year. The incidence of male breast cancer is increasing in the USA, probably because of increasing life expectancy.

Breast cancer is widely considered a woman’s disease, but men are also at risk. Around 1 in 1,000 men will develop breast cancer at some point in their lives. Although their risk for breast cancer is low, knowledge of male breast cancer symptoms can help men to recognize this potentially deadly disease.
