Researchers find a strange link between marathon running and cancer

Some of the most physically convenient people in the world may have unique health risks. New research reveals a possible link between the marathon and colon and rectum cancer.

Oncology at the Innova C. Cancer Institute in Virginia conducted the study, which examined the relatively young Colones who managed many long distance races. They found that these contestants have a much higher rate than the presence of dangerous glandular tumors (a type of benign tumor), which was expected of their age. Although the results are primary and require more confirmation, they may indicate a real relationship between colon and rectum cancer and extremist physical activity.

“He tells us that there is a sign here,” David Lieberman, a digestive disease specialist and a professor at the Oregon University of Science and Science is not linked to the study, He said New York Times on Tuesday. “We did not expect these rates of high -risk glandular tumors, which are the lesions of the cancer of the cancer, in a lifetime category like this.”

Mysterious

The main researcher, Timothy Cannon, was inspired to perform the study after three young patients with colon and rectal cancer, all of whom manage Ultramaraaths (defined as any race longer than 26.2 miles). His patients were not only suitable, but they were also younger than the typical condition, which is 40 years old.

In 2022, Canon and his colleagues Start The athletes recruit the endurance for their future studies. All volunteers were running at least two regular marathon; They also did not have a family history of colon and rectum cancer or other phenomenal risk factors. Finally, 100 athletes between the ages of 35 and 50 participated and gave colonoscopy.

The researchers went looking for advanced tumors in Collons, their volunteers, and those with large or relatively unusual benign tumors. Although this growth is the same benign, it suffers from a greater risk of cancer from other benign tumors. Then compare the rate of finding these benign tumors in athletes to historical trends.

About 1.2 % of people in the 1940s are expected to be at risk of colon and rectal cancer who have advanced glandular tumors, according to researchers. On the acute contrast, 15 % of the contestants who studied them had, while nearly half of them had benign tumors in general.

The researchers wrote in their study: “There is a justification for looking at the refined examination strategies for this population,” the researchers wrote in their study.

Leave a lot to understand

team foot Its results earlier this year at the annual conference of the American Association of Clinical Oncology. This means that this study has not yet been subject to the official theoretical review process. Authors also rush to note that their work is not a final evidence that endurance can cause colon and rectal cancer.

Assuming that this link is causing, there is still a burning issue. As the 5K run on the weekend will be known, running can sometimes lead to seizures of intestinal distress (bearing the same name Diarrhea). These injuries are sometimes caused by temporarily restricted blood flow to the intestine that destroys nearby cells. Researchers are likely to be, it is possible that volunteer contestants with blood flow loss can develop a kind of chronic inflammation that makes cancer more vulnerable to appearing.

At this stage, this is only one hypothesis of what may happen here. Researchers say future studies should try to confirm their findings, as well as decipher the causes and risk factors that can explain these potential risks.

All that has been said, this research should not scare anyone away from running or any other form of the heart. Many health benefits of regular physical activity – which include an important way a Decreased Among the at least eight different types of cancer – still exceeds the risks of the average person.
