About Chest Surgery

How would having top surgery influence my chest cancer risk?

Top surgery is different from surgery to treat or prevent chest cancer.

  • Top surgery: Main goal is gender care, not cancer prevention 
    • Removes much, but typically not all, of the tissue that can get chest cancer. 
    • Some tissue is left behind to build a masculine chest shape.
    • For some people, the nipple is kept on the chest. Some people get nipple grafts.  
  • Cancer risk-reducing mastectomy: Main goal is reducing chest cancer risk as much as possible
    • A surgery for people at high risk for chest cancer based on their family history of cancer or genetic risk. 
    • This surgery might also be done after someone has cancer to prevent the cancer from coming back.
    • Often includes removing the nipples.

Top surgery (left) leaves tissue behind to make the chest shape. During cancer risk-reducing surgery (right), the surgeon removes all tissue between the skin and the muscle wall.
