The main symptom of breast cancer in men is a hard lump in one of your breasts. The lump is almost always painless.
The lump is usually located underneath the nipple and areola (the circle of dark coloured skin that surrounds the nipple).
However, it is important to note that the vast majority of breast lumps are due to a condition called gynaecomastia. This is a common, non-cancerous condition where male breast tissue becomes enlarged.
