Male Breast Cancer

Breast cancer may occur in men. Although it is relatively rare—less than 1% of breast cancer diagnoses in the United States are in males—men may develop the disease at any age. 

Radiation exposure, high levels of estrogen, and a family history of breast cancer are risk factors for male breast cancer. In particular, men with a mutation of the BRCA2 gene are at increased risk of developing breast cancer.

Approximately 2,800 men in the United States will be diagnosed with breast cancer in 2025 and about 510 will die from the disease, according to federal statistics.
