Exercise tied to better colon cancer survival odds
People with colon cancer who spend more time walking and fewer hours on the couch are less likely to die over the seven to eight years after being diagnosed, a new study suggests.
The findings don't prove exercise itself boosts a person's survival chances, researchers said. But the pattern held even after the study team took into account how advanced patients' cancers were, their age and other aspects of their diet, lifestyle and health.
"Any activity is better than none," including walking, stretching and gardening, said Peter Campbell, the lead researcher on the study from the American Cancer Society.
"Five to ten minutes at a time is fine, and the type of activity we're talking about here, this isn't marathon running or climbing the Alps."
Campbell's analysis included about 2,300 people who developed colon cancer out of an initial pool of 184,000 volunteers in a cancer prevention and nutrition study launched in 1992.
Over an average of eight years after their diagnosis, 846 people with colon cancer died - including 379 from cancer.
The researchers found that study participants who exercised the most - equal to two and half hours of walking per week or more - both before and after being diagnosed were 28 to 42 percent less likely to die during the follow-up period than those who barely exercised at all.
