MOHS Skin Surgery at Kelsey-Seybold Clinic MOHS surgery is a specialized technique for removing commonly occurring skin cancers while sparing the greatest amount of normal healthy tissue. MOHS differs from other techniques in that cancerous cells are removed in layers and examined during surgery rather than afterward. As the surgery gradually proceeds, each layer is removed and examined microscopically until the skin cancer is completely removed. These during-surgery microscopic examinations target and remove the offending cells while sparing normal tissue and minimizing scarring for better cosmetic results.
