New test could prevent unnecessary surgery for common skin precancers

This study aims to create a diagnostic test that can tell the difference between precancerous skin lesions (actinic keratoses) that will turn into skin cancer and those that will go away on their own. Researchers will study tissue samples from 140 patients with skin cancer and precancerous lesions. The goal is to help doctors decide which spots need early removal and which can be left alone, reducing unnecessary surgeries and scarring.
