Dermatologists Warn 13-Fold Melanoma Risk From Minimalist Swimwear on UV-Naive Skin

Summary
A 1986 case-control study found women who wore bikinis or bathed nude at ages 15 to 24 had a 13.0 rate ratio for trunk melanoma versus one-piece wearers, a risk dermatologists say may grow as cheeky and string styles go mainstream.
Swiss epidemiologic data identified the buttocks as historically low-risk precisely because conventional clothing kept them out of the sun; specialists say intense intermittent exposure can shift that pattern and is linked to BRAF-mutated melanoma pathways.
Gen Z misinformation may be compounding the danger: 37% were unaware of at least one sunburn risk in a 2024 AAD survey, 57% endorsed tanning myths, and half reported at least one sunburn that year.
A stage I melanoma case on the buttocks also highlights detection and treatment challenges, with lesions easy to miss and surgery in the gluteal area carrying healing and infection risks.
Dermatologists advise sunscreen and reapplication on newly exposed areas, UPF coverups out of the water, and full-body skin exams that include the posterior trunk and gluteal region.
