Identifying Non-Melanoma Skin Cancers Through Visual Characteristics

Dr. George Parag, a dermatologist at Roswell Park Comprehensive Cancer Center, discusses non-melanoma skin cancers, focusing on basal cell and spamosal carcinomas. He explains how to identify these cancers by their unique characteristics and introduces the ABCDEF method for recognizing problem pigmented lesions. The method includes checking for asymmetry, border irregularity, color variation, increased diameter, evolution, and the 'funny' or 'funky' factor, which refers to the ugly duckling sign. This approach helps in early detection of skin cancer.
