Can men get mammograms and if not how do they know they have breast cancer?

Yes: Breast cancer in men is rare, but it happens. Men over 60 are more likely to get breast cancer. Because men have less breast tissue, they feel or see a lump. So men should feel their breasts regularly, especially older men. And yes, if there's a lump, men get a mammogram! but not screening mammograms...Only if there's a lump.

Men can: get mammograms. A small percentage of breast cancers occur in men, so if a man has a breast lump, a mammogram and/or ultrasound may be indicated.
