Dear mmadd29, Male breast cancer is rare, but one out of every 150 cases of breast
cancer involves a man, usually in men
over 60 years old. A painless breast
lump is the most common sign of breast cancer, although most breast lumps in men are benign (non-cancerous) and are related to some other cause. You do not describe a specific lump in the breast and there could be a certain amount of difference between breast size, without this being a problem.
