Enlargement of male breast tissue. It can occur at any age and affect one or both breasts.
Surgery is usually for cosmetic reasons, however may be used to control symptoms (pain) or exclude a more sinister process.
Breast cancer in men is rare, accounting for less than 1% of all cancers in men, and indeed, less than 1% of all breast cancers.
Treatment will require surgery and referral to a medical oncologist, radiation oncologist and a clinical geneticist (often there is a link between male breast cancer and a breast cancer gene BRCA2).
