There may now be intriguing evidence that caffeine may act as a molecular sunscreen. According to recent research, people who drank more than four cups of coffee on average per day, had a 20% lower risk of developing melanoma over ten years.
Melanoma, the deadliest form of skin cancer, is triggered by DNA damage in skin cells caused by ultraviolet (UV) rays from the sun or tanning beds. As the mutations cause the cells to grow abnormally, they can metastasize and become fatal. In light of this potentially dire outcome, dermatologists urge their patients to shield themselves from the sun’s damaging effects with sunscreen and protective clothing and to shun tanning beds. The only way to truly know if you have skin cancer is to get a screening from a reputable medical professional.
