U.S. Dermatologists and Canadian Experts Emphasize Annual Skin Cancer Screening and Sunscreen Use

Dermatologists in New York City advise that adults undergo a full‑body skin‑cancer screening each year. The examination, performed by a board‑certified dermatologist, uses a dermatoscope to assess moles, freckles, lesions and other skin changes, helping to identify early‑stage melanoma, basal‑cell or squamous‑cell cancer when treatment is most effective. People with a personal or family history of skin cancer, fair skin, extensive sun exposure, or prior burns are urged to prioritize these exams.

Medical professionals across North America, including Dr. Mitch Shulman of the McGill University Health Centre, warn that social‑media misinformation is undermining sunscreen use. They stress that both chemical (e.g., avobenzone, oxybenzone) and mineral (zinc oxide, titanium dioxide) sunscreens are safe when applied correctly, and that broad‑spectrum products with SPF 30 or higher, applied 30 minutes before exposure and reapplied after water exposure or sweating, remain essential. Additional protection includes UPF‑rated clothing, wide‑brimmed hats and UV‑blocking sunglasses, and avoiding peak UV hours.

Together, these messages aim to improve public awareness of UV radiation as a proven carcinogen and to promote early detection and consistent sun‑protection practices for all skin types.
