UV causes skin cancer - but the majority of them (10:1) are basal cell and squamous cell carcinomas. These have a 99-100% 5-year survival. While UV exposure can increase the risk of melanomas, it makes you less likely to die from them [1]. The UVA-mediated release of nitric oxide from the skin improves your cardiovascular health and you are far more likely to die of CVD than skin cancers, especially if you screen for them. Early stage melanomas have a 99.6% 5-year survival.
