Overexposure to UV radiation increases the risk of which condition?

Explanation:
UV radiation damages the DNA in skin cells, and that damage can accumulate into mutations that lead to cancer. UVB light directly harms DNA, while UVA penetrates deeper and promotes damage through free radicals, contributing to the risk over time. While UV exposure can also cause wrinkles by breaking down collagen and elastin, it’s not a direct cause of acne or dandruff. Protecting skin with sunscreen, protective clothing, and shade helps reduce this cancer risk.
