Breast cancer is commonly thought to occur only in women, but in rare cases men can also develop breast cancer. The main symptom of breast cancer in men is a lump in the breast, and in some cases the nipple or skin may also appear abnormal. If you have a breast lump or other abnormalities, don’t be shy about seeking medical attention. Cancerous breast lumps usually have these symptoms: they occur only in one breast, they grow under or around the nipple, they are usually painless (in rare cases they can be painful), they feel hard or tough, they are immovable, they are not smooth, and they gradually increase in size over time. Most breast lumps or swellings are not cancer, such as enlarged breast tissue in men (gynecomastia), fatty lumps (lipomas) or cystic lumps (cysts), etc. A physical examination by the consulting physician can be performed first in order to evaluate the lump and whether further testing and breast cancer screening is needed. There are other symptoms of male breast cancer such as nipple turning inward, fluid leaking from the nipple (nipple discharge) that may be bloody, scabies or rash around the nipple, hardening, redness or swelling of the nipple or surrounding skin, and small lumps in the armpit. If the cancer has spread to other parts of the body, such as the bones, lungs, or liver, symptoms of associated metastases may occur, such as: weakness, bone pain, shortness of breath, nausea, itchy skin, yellow stained eyes, yellow urine, yellow stained skin (jaundice).
