Sunscreen Use for Skin Cancer Prevention
Abstract
Daily sunscreen use reduces the incidence of squamous cell carcinoma but not the incidence of basal cell carcinoma. (Strength of Recommendation [SOR]: B, based on a single randomized controlled trial with less than 13 years of follow-up). It is unclear whether there are longer-term effects. There is no consistent, conclusive evidence that sunscreen use prevents melanoma. (SOR: C, meta-analysis of case-control studies).
