Mohs Micrographic Surgery

What Is Mohs Micrographic Surgery And What Kinds Of Cancer Does It Treat?

Mohs micrographic surgery is perhaps the most effective treatment for both Basal cell carcinoma and Squamous cell carcinoma. This procedure was developed by Dr. Frederic E. Mohs and has been found to be very effective in the removal of non-melanoma skin cancers. This procedure is done in the office setting using local anesthesia.

Mohs micrographic surgery is often used when the cancer is very visible, for example on the face, because it reduces the healthy skin tissue that is surgically removed. Mohs micrographic surgery is also used on large skin cancers and skin cancers which have borders that are difficult to identify.

While other procedures examine tissue samples after they have been removed, Mohs micrographic surgery is specially designed so that the tissue is microscopically examined during the procedure rather than afterwards. This way all of the cancer cells can be removed while minimizing the healthy tissue that is removed. A thin layer of tissue is removed and then examined microscopically for cancerous cells as soon as it is removed. Tissue samples are color coded and a map is created to show where the remaining cancer cells are located. This process continues until the cancerous cells no longer show up when a layer is examined. Because the layers of tissue are thin, a lesser amount of the healthy tissue is removed.

As always, make sure your Mohs surgeon is a Board-Certified Dermatologist.
