How effective is mastectomy for breast cancer in men?

Because men have less breast tissue, a tumour may be close to the nipple or chest wall. Mastectomy removes the breast tissue and may include removal of the nipple and areola. Nearby lymph nodes may be sampled or removed to check whether cancer has spread beyond the breast.

Effectiveness is assessed using the tumour size and position, lymph-node findings, cell type, hormone-receptor and HER2 results, and whether there is evidence of spread elsewhere. These results can lead to additional treatment such as hormone therapy, chemotherapy, targeted therapy, or radiotherapy.

Before surgery, ask how much tissue will be removed, whether lymph-node surgery is needed, and which tests will guide treatment afterward. Discuss chest appearance, sensation changes, scar care, movement restrictions, and whether an external prosthesis or reconstruction is relevant to you.

During recovery, follow instructions for the incision and any drain, attend pathology and oncology appointments, and begin shoulder exercises when your team advises. Tell the team about persistent pain, reduced movement, numbness, or swelling in the arm.

Call your care team for fever, increasing redness or warmth around the incision, pus, worsening pain, wound separation, or a drain that stops working unexpectedly. Get urgent help for heavy bleeding, severe breathlessness, chest pain, or fainting.

Is mastectomy the safest surgical option for my tumour? Will lymph nodes be checked? Which laboratory results will determine further treatment? What chest-wall changes and sensation loss are possible? When should I start arm exercises and follow-up imaging?
