Mohs Micrographic Surgery
Dr. Christopher Weyer is a dermatologist and skin cancer specialist in Tucson, Arizona who specializes in Mohs micrographic surgery. Mohs surgery is named after Dr. Frederic Mohs, who pioneered the technique. Mohs Surgery offers the most effective and advanced treatment for skin cancer with the highest potential rate of cure – up to 99% for primary basal cell carcinoma. The advantages of Mohs are assurance of complete cancer removal and minimal loss of healthy tissue surrounding the cancer. This results in smaller wounds and improved cosmetic and functional outcomes. Typically the wound is repaired the same day. At Dermatology and Plastic Surgery of Arizona we have two surgeons trained in different disciplines to optimize your skin cancer reconstruction.

The Mohs process
The roots of a skin cancer may extend beyond the visible portion of the tumor. If these roots are not removed, the cancer will recur.
The visible tumor is surgically removed.
A layer of skin is removed and divided into sections. The ACMS surgeon then color codes each of these sections with dyes and makes reference marks on the skin to show the source of these sections. A map of the surgical site is then drawn.
The undersurface and edges of each section are microscopically examined for evidence of remaining cancer.
If cancer cells are found under the microscope, the ACMS surgeon marks their location onto the “map” and returns to the patient to remove another layer of skin – but only from precisely where the cancer cells remain.
The removal process stops when there is no longer any evidence of cancer remaining in the surgical site. Because Mohs surgey removes only tissue containing cancer, it ensures that the maximum amount of healthy tissue is kept intact.
