Enjoy Your Coffee Caffeine On Your Skin- It May Prevent Some Skin Cancers


A new study published in the Proceedings of the National Academy of Science discussed the mechanism of how caffeine might protect against certain skin cancers and that could lead to better sunscreens. Suspecting that the response of a gene called ATR that is suppressed when caffeine molecules are around might be involved in the protective role of caffeine, researchers created genetically modified mice whose ATR genes were deficient and then exposed them to ultraviolet light until they developed skin cancer. After 19 weeks of IV exposure, they found that these mice developed 69% fewer tumors than those that had fully functioning ATR genes. In addition, the tumors in the genetically modified mice developed three weeks later than in the control group. After 34 weeks of UV exposure, all mice developed tumors, mainly a non-melanoma type called squamous cell carcinoma (SCC). They concluded ” All of this suggests the possibility that caffeine, possibly (ap0plied to the skin)), would have an inhibitory effect on sunlight induced skin cancer.”
