Lasers to Treat and Prevent Skin Cancer

The discussion highlights the growing interest and application of laser technology in dermatology, particularly for treating and preventing skin cancer. Using lasers, dermatologists can target and improve skin health, thereby reducing the risk of non-melanoma skin cancers, a prevalent issue in the U.S. The presentation first describes various laser treatments that have shown promising results in clearing basal cell carcinomas, achieving high clearance rates with minimal scarring. It emphasizes advancements in pulsed dye laser and ND: YAG laser treatments that have effectively targeted cancerous cells without significant adverse events. Additionally, the presentation discusses innovative methods such as the use of gold nanoparticles, which show potential for enhancing laser treatment efficacy. It further elaborates on clinical studies proving that both ablative and non-ablative laser procedures significantly lower the incidence of actinic keratoses and skin cancers. Results from randomized controlled studies indicated that these laser treatments lead to a four-fold reduction in actinic keratoses and substantial decreases in skin cancer development. Lastly, the ability of these treatments to rejuvenate skin and enhance its response to UV damage is underscored, reinforcing the concept that lasers not only treat existing skin conditions but also play a preventive role in skin cancer management.
