Breast cancer in males
Breast cancer is often thought of as a condition that only affects women, but men can also develop it. It's much less common in men than women. The cancer develops in the small amount of breast tissue men have behind their nipples. The most common symptom is a hard, painless lump in one of the breasts. However, the vast majority of breast lumps are caused by a condition called gynaecomastia. This is a common non-cancerous condition where male breast tissue becomes enlarged. Breast cancer in men can also cause nipple problems, such as the nipple turning in on itself (retraction) or nipple discharge. The cause of male breast cancer is unclear, but factors known to increase your chances of developing the condition include: age – most cases affect men over the age of 60 having a family history of breast cancer (male or female) obesity – a body mass index (BMI) of 30 or more
