Male Breast Cancer
Male breast cancer (MBC)
Breast cancer in men is rare and accounts for 1% of all breast cancer diagnoses. In the UK, some 350 men are diagnosed annually with around 2470 in the USA. Data from cancer registries in the UK and USA suggests that the numbers of men receiving a breast cancer diagnosis has been rising gradually since the 1970s.
Typically over 60, although all ages can be affected
Breast cancer is found predominantly in women, but it can also affect men. Breast cancer in men is around 100 times less common than it is in women.
Breast tissue in men is typically situated directly behind the nipple.
A unilateral, firm, painless, or minimally tender mass behind or adjacent to nipple or in axilla; changes in appearance of the nipple, e.g., inversion; and nipple discharge or bleeding. Because breast cancer is perceived by the majority of general public as a gender-specific condition, men often...
