Results of 12 prospective U.S. and European cancer studies were pooled (1.44 million participants) to analyze the impact of high vs low physical activity levels. Leisure-time physical activity was associated with lower risks for 13 common cancers types. Most of these benefits were present regardless of body weight or smoking history (lung cancer excepted). Melanoma was an exception, probably because of more unprotected exposure to sunlight.
PositiveTip: Lower your cancer risk by engaging in moderate to vigorous intensity physical activity daily.
