Sunburn increases the risk of developing skin cancer, including melanoma.

INSUFFICIENT LEANING
Recorded sources
7 sources for · 0 against

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that sunburn increases the risk of developing skin cancer, including melanoma?

Unclear. Several peer-reviewed sources partially support the claim: a 2023 Mendelian randomization study found childhood sunburn causally associated with melanoma and non-melanoma skin cancer, and a 2025 meta-analysis found sunburn history significantly associated with cutaneous squamous cell carcinoma. Other items link UV exposure to skin cancer generally, but none settles the full claim across all skin cancers at the strength asserted.
