After the area is numbed, the area will be cleaned with an antiseptic solution and sterile drapes placed. Dr. Humphreys will then remove the visible tumor and a thin layer (1-2mm) of surrounding tissue around and underneath the skin cancer. The tissue is then taken to the lab and processed. Dr. Humphreys then examines the tissue under the microscope to determine if there is any skin cancer remaining. If any skin cancer is present, a map is made to determine exactly where it is. This takes approximately 25-30 minutes depending on the size of the tumor. The procedure is then repeated until no skin cancer remains. Smaller skin cancers may be removed in one stage while larger tumors may require multiple stages and hence more time to remove.

After the skin cancer is removed, the wound is usually sutured to provide the most rapid healing and best cosmetic result. The duration of the repair process varies widely depending on the size and location of the skin cancer and ranges from 20-45 minutes.

The total duration of the procedure ranges from an hour to the entire day for more complicated cases. We ask that you clear your schedule for the day in case your procedure takes more time than anticipated. We know that waiting for the results is difficult. Please bring a book or magazine with you to read while you are waiting. Some patients like to bring their own music to help them relax as well. You may also have someone wait with you. We request that each patient only bring one person with them due to limited space in the patient rooms and waiting area.
