Ultraviolet (UV) radiation from the sun is the primary cause of skin cancer. UV rays, specifically UVB and UVA, can damage the DNA in skin cells.
Exposure to UV radiation can lead to mutations in skin cells, which can result in the development of skin cancers, including melanoma, basal cell carcinoma, and squamous cell carcinoma.
While other electromagnetic radiations have different effects (e.g., infrared causes heat), UV radiation is the most harmful component of sunlight in terms of skin damage and cancer risk. The ozone layer absorbs most of the sun’s harmful UV radiation, but some reaches the Earth’s surface.
