Typically, there's not enough breast tissue on a person assigned male at birth to perform a standard mammogram. According to Johns Hopkins Medicine, only about 1 percent of all breast cancers develop in men.
However, some people may still need to be screened. For example, people who have certain genetic mutations or other risk factors should be screened for both breast and prostate cancers, regardless of the gender they were assigned at birth. Make this decision with the help of a doctor, based on your individual risk.
