Solar UV radiation (sunlight)
Summary
Ultraviolet radiation from the sun is associated with melanoma and other skin cancers.
Detail
Solar UV radiation is Group 1 with sufficient evidence for melanoma and non-melanoma skin cancers. WHO and the major cancer-prevention bodies (including Cancer Council Australia, which leads on UV guidance) recommend limiting midday sun exposure, seeking shade, wearing protective clothing and broad-brim hats, using UV-blocking sunglasses, and applying broad-spectrum sunscreen (SPF 30 or higher) reapplied every two hours on uncovered skin.
