Research letter examines firefighters and skin cancer risk

A recent study examined the skin cancer history and habits of active Florida firefighters. The research found that 4.5% of participants had skin cancer, with a significantly higher frequency of melanoma (0.7%) compared to the general U.S. population. Non-work-related sun exposure may be contributing to this increased risk.
