What's the difference between standard skin cancer removal and Mohs surgery? Ashley McGuinness, MD, FAAD breaks down this specialized technique that achieves remarkable 98-99% cure rates while preserving healthy tissue. While standard excisions examine only 1-2% of margins, Mohs surgery meticulously evaluates 100% through a precise mapping approach.
During this eye-opening conversation with host Dr. Jason Edwards, Dr. McGuinness addresses the alarming 1.8% annual rise in skin cancer rates since 2000. She attributes this to better detection methods, our aging population, and the consequences of tanning bed popularity in past decades. When discussing internet myths claiming sunscreen causes cancer, she provides clear evidence of UV radiation's harmful effects while offering practical alternatives like physical blockers or UPF clothing for those with chemical concerns.
The discussion takes a fascinating turn toward technology as Dr. McGuinness reveals how AI is transforming dermatology. From full-body mole mapping to algorithms that detect subtle changes invisible to the human eye, these advances complement clinical expertise without replacing it. For self-examination, she emphasizes the critical "ABCDE" approach to identify potential melanomas: check for Asymmetry, Border irregularity, Color variations, Diameter larger than a pencil eraser, and most importantly, Evolution over time.
Beyond cancer detection, the conversation explores factors in skin aging, from UV exposure and dehydration to facial movements and lifestyle choices. Dr. McGuinness shares simple strategies anyone can implement: staying well-hydrated, using daily sunscreen, and avoiding tobacco and excessive alcohol. Whether you're concerned about skin cancer prevention or preserving your skin's youthful appearance, this episode delivers practical wisdom from a leading specialist in the field.
