“We have now shown that modifiable lifestyle factors that were known to reduce the incidence of colorectal cancer can also reduce the mortality in cases diagnosed with the disease,” Dr. Andrew M. M. Haydon told Reuters Health. “This strengthens the argument supporting the public health message of ‘healthy living.'”
Haydon, from Monash Medical School in Melbourne, Australia, studied records from more than 40,000 patients diagnosed with colorectal cancer between 1990 and 1994.

In fact, 73 percent of exercisers survived at least five years, compared with 61 percent of non-exercisers.
