Breast cancer is a very rare disease in males. However, any lump or growth of tissue underneath the nipple is a cause of concern and can potentially be a serious problem. Lumps caused by cancer are usually not underneath the nipple however, breast tissue from gynecomastia grows in this area. Breast cancer feels different than the breast tissue of gynecomastia.
