Risks

As with any surgical procedure, Mohs surgery carries the risk of:

  • Bleeding
  • Pain or tenderness around the surgical site
  • Infection

Other complications that may result from Mohs surgery are uncommon but may include:

  • Temporary or permanent numbness surrounding the surgical area, if small nerve endings are cut
  • Temporary or permanent weakness of the surgical area, if the tumor is large and a muscle nerve is severed
  • Itching or shooting pain in the affected area
  • An enlarged scar (keloid)
