What is Mohs surgery?

Mohs surgery is a specialized method of removing skin cancers primarily on the face with the highest possible cure rate and smallest possible scar. During the surgery, a patch of cancerous skin is removed and then examined under a microscope to determine if more skin needs to be removed. The method minimizes how much normal skin is removed.

Moh's surgery involves dermatological microscopic excision of small tumor at a time with evaluation for free margins. Once the edges are clear, the defect can be closed with a flap reconstruction or primarily if small. 

Mohs micrographic surgery is the treatment of choice for the majority of high-risk basal cell and squamous cell cancers. The procedure involves the removal of a skin tumor one layer at a time. The layers are immediately examined under a microscope to detect cancer cells. The procedure ensures complete removal of all cancer cells while assuring optimal cosmetic results by minimizing tissue to be removed.
