The researchers shocked to discover the healthy habit that can cause colon cancer
Exercise reduces your risk of mortality. But an extreme race could have the opposite effect.
Earlier this summer, we reported a exciting study This revealed that patients with colon cancer who participated in a three -year exercise coaching program experienced 28% less cancer recurrences and were 37% less likely to die. In other words, the results have shown that exercise could be a powerful remedy against colon cancer. However, new research suggests that all The exercise is beneficial to try to reduce your risk of this cancer of the constant increase.

Research connects marathons to an increased risk of colon cancer.
New research presented in a American clinical oncology company The conference examined the risk of precancerous adenomas (an advanced polyp) in the colon in long -distance runners.
The study was led by Timothy cannon , MD, oncologist reaches inova SCHAR cancer in Fairfax, Virginia. As Cannon explained to The New York Times , his research was influenced by three of his patients, who, although they are young (40 years or less), physically active and a healthy weight, came to him with advanced colon cancer and died later.
In itself, it is not completely shocking. After all, colon cancer is currently the deadliest cancer of young men and the second deadliest of young women. In addition, colon cancer cases among Americans aged 30 to 34 increased by 71%.
But what a gun did Finding shocking was that his three patients exercised more than most people. "Two two ultramarathons of 100 miles, and one had completed 13 half-marathons in a single year", the Times reported.
Thus, for his study, he enlisted 100 participants aged 35 to 50 who had finished at least two ultramarathons (50 km or more) or five recorded marathons (26.2 miles). None of them had personal history or family history of colon cancer or related risk factors.
A panel of gastroenterologists, pathologists and oncologists examined the results of the colonoscopy of the participants and determined the following:
- 39% had at least one polyp
- 15% had advanced (precancerous) adenomas
THE Times puts this in perspective by noting that the average rate of advanced adenomas in American adults at the end of the forties 4.5% And 6% .

How does long distance race influence colon cancer?
This study proves only one link between long -distance functioning and advanced adenomas, not causality. It is also important to note that it was a relatively small study. However, doctors still have theories to how The marathon race could influence colon cancer.
"I found an additional reason to believe that there could be a link between endurance sports and an increased risk of colorectal cancer when I read research on reducing blood flow to the stomach, intestines and nearby organs which often occur during painful exercise", Cannon Written in 2022 When he started his research.
"During a 50 -mile race - six or seven hours for an elite athlete - the body covers a large amount of blood flows with the active legs of the legs," he continued. "The loss of blood flow to the intestine during this intensive exercise can cause ischemia, resulting in cellular damage and a more disorderly and rapid cell renewal process."
However, other doctors have hypothesized that the connection more concerns long -distance runners being more likely to miss the symptoms of colon cancer.
Like the Times Explains that endurance runners "often develop gastrointestinal symptoms which they reject as benign", in particular diarrhea and bloody stool. There is even a term for this - the runner trots - who refer to sudden and frequent desire to go to the toilet which often occurs during or after a long race.
Cannon plans to continue his research to establish more concrete research on the link between long distance race and colon cancer.
