According to the British “Daily Mail” reported on March 2, the “British Journal of Cancer” published a new U.S. study found that regular exercise can significantly reduce the risk of bowel cancer. Thirty minutes of exercise a day can reduce cancer-prone intestinal polyps by one-third. Scientists at the University of Washington School of Medicine analyzed the results of 20 related studies and found that people who exercised regularly were 16 percent less likely to develop intestinal polyps and 30 percent less likely to have larger polyps or cancerous polyps. People who are accustomed to a sedentary lifestyle are more likely to develop malignant intestinal polyps. The new study leader, Kathryn K. Dr. Wallin said regular exercise helps promote a healthy immune system, reduce intestinal inflammation and help lower insulin levels, among other things. Dr. Wallin said it is well known that an active lifestyle can help prevent bowel cancer, but this new study is the first to investigate multiple possible lines of evidence suggesting that reducing the incidence of intestinal polyps is the most critical factor in preventing bowel cancer. The new findings further suggest that the benefits of regular exercise as part of a healthy lifestyle are numerous and include a reduced risk of bowel cancer. Deborah Alcina, president of Bowel Cancer UK, said that bowel cancer is a major cause of death. Alcina said, bowel cancer is the third largest cancer, only in the United Kingdom each year, about 38,600 new cases of bowel cancer patients. In addition to being physically active, it is important to be proactive in bowel cancer screening, and where possible, bowel cancer screening measures such as colonoscopy are key to detecting early stage bowel polyps. The earlier intestinal polyps are detected and removed, the lower the risk of bowel cancer. Cancer Research UK’s head of health information, Sara K. Seaholm said research evidence shows that maintaining an active exercise lifestyle can prevent thousands of cancer cases each year. The new study further confirms that exercise can prevent the risk of bowel cancer. Cancer Research UK recommends at least half an hour of moderate-intensity exercise each day, such as a brisk walk or something of comparable intensity that feels slightly out of breath. Seaholm also said that adequate physical activity also helps to maintain a healthy weight, not overweight, the risk of cancer will naturally drop significantly.
