The New York Times is reporting on multiple studies today which indicate that vigorous exercise is associated with reduced cancer risk. Unlike the Time’s headline, there is no question about it. First, this study from the British Medical Journal says that “mean intensity of leisure-time physical activity is inversely associated with the risk of premature death from cancer in men.” In other words, people who had a rigorous exercise level were less likely to die of cancer. However, that study did only involve 2560 men. By contrast, this study from the British Journal of Cancer took into account 52 studies of various sizes. The verdict remains the same: “an inverse association between physical activity and colon cancer in both men and women,” or a workout a day is likely to keep cancer away.
