Treatment of eyelid skin cancer is always surgical. After the diagnosis is made with a biopsy, the cancer is removed very carefully to make sure that no malignant cells are left behind. There are different techniques to accomplish this. The most efficient is called Mohs micrographic surgery. Mohs surgery has revolutionized skin cancer treatment because it allows surgeons to remove the cancer completely while conserving healthy tissue around the tumor. This makes reconstruction of the anatomical site much easier and the result more aesthetic.
