Pathologists: medicine’s private investigators

Photo illustration of skin tissue resection to show malignant melanoma of the skin. “The operation is intended to cure a skin cancer patient by taking the cancer out with a “safety margin” of 1-2 cm around it,” said Dr. Al Elsayed, David Grant USAF Medical Center staff pathologist. “The undersurface of the specimen is colored by a special non-running ink so we can measure under the microscope how far is the cancer from to the margin of the specimen that the surgeon removed…If the cancer is "too close" the clinician may go back and remove more tissue from that particular location to provide an additional safety margin to make sure the cancer does not return.” (U.S. Air Force photo illustration by Tech.
