Previous studies have suggested that physical activity decreases
the risk of certain cancers. University of California, Los Angeles
(USA) researchers have found that men who work in jobs that require a
continuous level of high physical effort are at reduced risks of
developing prostate cancer. The team compared the physical activity of
392 workers who developed prostate cancer with 1,805 men similarly
employed and of similar age. Amongst a group of aerospace workers, 64%
of whom were involved in work that required sustained and high levels of
physical activity, the odds for prostate cancer were 45% lower, as
compared to their less active counterparts.
