Surgery is the main treatment for breast cancer. Most men only have a small amount of breast tissue, so the most common operation involves taking away all the breast tissue and the nipple. This is called a mastectomy. You will usually have some or all the lymph nodes removed from the armpit during this operation.
Sometimes, the surgeon may be able to remove only the area of the cancer with some surrounding healthy tissue. This operation is called a wide local excision. For some men it may mean they keep their nipple. You might hear it called a lumpectomy or breast-conserving surgery.
After this operation, the pathologist looks at the tissue that has been removed to see if there is an area of normal cells around the cancer. This is called clear margin. If there are still cancer cells at the edge of the removed breast tissue, you will need to have a mastectomy.
Your surgeon will talk to you about the type of operation that is recommended for you. They can also answer any questions you may have.
