New research is adding to evidence of the power of caffeine to fight skin cancer. Researchers rubbed caffeine and another compound, called EGCG, on hairless mice who were exposed to high levels of sunlight. They found the compounds together help ward off skin cancer. Previous animal studies have shown that oral forms of caffeine can protect against skin cancer, but this research is among the first to test a topical cream.
We don't know yet if humans could benefit like the mice, but the research at Rutgers University continues. The study is published in the proceedings of the National Academy of Sciences.
