Breast cancer isn't just a woman's disease. Men also have breast tissue that can undergo cancerous changes. While women are about 100 times more likely to get breast cancer, any man can develop breast cancer. Male breast cancer is most common between the ages of 60 and 70.

The prognosis for male breast cancer is the same as for breast cancer in women. In the past, male breast cancer was often diagnosed at a more advanced stage, which may have led people to believe it had a worse prognosis. Although male breast cancer and breast cancer in women are similar, important distinctions such as breast size and awareness affect early diagnosis and survival in cases of male breast cancer.
