Mohs surgery

From WikiMD's Wellness Encyclopedia

Mohs surgery, also known as Mohs micrographic surgery, is a precise surgical technique used to treat skin cancer. During Mohs surgery, layers of cancer-containing skin are progressively removed and examined until only cancer-free tissue remains.

Introduction[edit | edit source]

Mohs surgery is named after Dr. Frederic E. Mohs, who developed the procedure in the 1930s. It is a gold-standard treatment for many types of skin cancer, particularly basal cell carcinomas and squamous cell carcinomas, due to its high cure rate and tissue-sparing nature.[1]

Procedure[edit | edit source]

The procedure involves removing a layer of skin and examining it under a microscope while the patient waits. If cancer cells are seen, another layer is removed and examined. This process is repeated until no cancer cells are found. As a result, Mohs surgery spares as much healthy skin as possible and reduces the need for a larger, more invasive surgery.[2]

Indications[edit | edit source]

  • Mohs surgery is typically used for skin cancers that:
  • Have a high risk of recurrence or that have recurred after previous treatment.
  • Are located in areas where it is important to preserve healthy tissue for cosmetic and functional reasons, such as eyelids, nose, ears, lips, fingers, toes, and genitals.
  • Are large or aggressive.
  • Have edges that are hard to define.[3]

Advantages[edit | edit source]

  • The main advantages of Mohs surgery include:
  • High cure rate: Mohs surgery has the highest success rate of all treatments for skin cancer.
  • Tissue-sparing: It's the most exact and precise method of tumor removal, minimizing the chance of regrowth and lessening the potential for scarring or disfigurement.[4]

Potential Complications[edit | edit source]

Although Mohs surgery is generally well-tolerated, potential complications can include infection, bleeding, and a delayed wound healing. The risk of any surgical complications is generally low.
