Moderate intake of caffeine can prevent skin cancer

Researchers in the United States have reported that their study in mice found that caffeine can remove cells damaged by ultraviolet radiation, thereby reducing the risk of skin cancer.

Moderate consumption of caffeine may prevent skin cancer, researchers say. In addition, because caffeine can also absorb ultraviolet rays directly, it can also be used as a sunscreen.

Previous studies have shown that caffeine inhibits a protease called ATR. In the new study, researchers at Rutgers University developed genetically modified mice in which the ATR protease was suppressed. After exposure to ultraviolet radiation, genetically modified mice developed skin tumors 3 weeks later than ordinary mice.
