#1 – Breast lumps
If you are a man who has breast cancer, then you may notice a painless, firm lump on the pectoral muscles that are located close to or behind the nipple area. However, these lumps are different than the ones found in benign gynecomastia – male enlarged breasts because of hormonal imbalance.
According to Brandon Behjatnia, MD, a Topline MD physician, gynecomastia is usually a soft and mobile mass but the cancerous lumps are neither soft nor mobile; they are extremely firm and can’t really move under the skin.
You have to do breast imaging and a needle biopsy (if necessary) to determine if the lump is cancerous.
