A provocatively titled article in the Los Angeles Times recently reported on the results of a study that found a link between a lowered incidence of cancer, and vigorous exercise:
In a massive effort to aggregate what’s known about cancer and exercise, researchers calculated that compared with people who reported spending the least time in “leisure-time physical activity,” those who got the most moderate to intense exercise reduced their risk of developing seven kinds of cancer by at least 20%.
The study goes on to name some questionably specific numbers, including the finding that colon cancer incidence could be reduced by 16% among regular gym-goers.
Now, a caveat. Epidemiological studies such as these are not controlled; they are not double blind; and they do not adhere to the gold standard for experimentation known as randomization, in which patients are randomized into groups, rather than self-selecting. Moreover the entire study relies on self-reporting, which is considered highly unreliable in most circumstances.
The upshot is this: we don’t know how to prevent cancer. But we do know, from far better studies, that exercise can reduce the incidence of other health issues including heart health and mental decline.
Whatever lifestyle you choose, it is wise to pursue regular colonoscopy screenings and take good care of your digestive health. If you’d like to learn more about how to live a healthy life, contact the Proctology Institute today.
