Are Exercise and Caffeine Protective Against Sun Exposure Skin Cancer?

A new study reported at the American Association of Cancer Research last week concluded that the combined effects of exercise and caffeine consumption may prevent skin cancer and also prevent inflammation related to other obesity-linked diseases. These results were found in a mouse model study but the researcher believes  “we may extrapolate these findings to humans and anticipates that we we would benefit from these combination treatments as well.”

Using mice at high risk of developing skin cancer researchers evaluated the effects of caffeine and exercise and found that mice that took a dose of caffeine and exercised on a running wheel had 62% fewer skin tumors. In addition, the volume of tumors also decreased by 85% compared with mice that did not exercise or take caffeine.  Positive effects were also found for either intervention alone but to a lesser degree.  Findings were a 27% reduction in skin tumors for caffeine only mice and a 61% reduction in tumor size. They found the tumor activity was reduced by 35% and the tumor volume by 70% in exercise-only mice. They also found that combined exercise and caffeine reduced weight and inflammation when mice were fed a high-fat diet of omega-6 fatty acid-rich  foods for two weeks.  These results were again higher when the two interventions were combined than with either one alone.
