The tumor along with a margin of normal appearing skin is marked with a sterile marking pen (see image below). The area is numbed using tiny needles. The tumor is cut out and often stitched together. The skin is sent to a laboratory and examined to ensure that the entire tumor has been removed. Sometimes all dissolvable stitches are used, otherwise sutures are generally removed within 7 to 14 days depending upon what area of the body the cancer is. There is usually minimal discomfort after the procedure. The pathology results may take up to 7 days and rarely longer. This treatment is 95% effective for the treatment of nodular basal cell carcinoma, superficial basal cell carcinoma, squamous cell carcinoma.
