Regular physical activity can extend colorectal cancer patients’ lives. In a study, scientists looked at the impact of exercise on the gut microbiome of cancer patients and reported a positive association. The gut microbiome is the largest portion of the body’s collection of bacteria and other microbes that live in and on the body, according to the National Cancer Institute. Researchers found physical activity was also beneficial to obese cancer patients, who typically have a less healthy gut microbiome.
The findings are an important step in understanding how a healthy gut improves colorectal cancer outcomes for patients. While other scientists have studied the effect of exercise on the microbiome among healthy individuals, this is the first study looking at the outcome in people with cancer.
The team found that regular physical activity can aid in creating a healthy gut microbiome, while also reducing inflammation. These findings were reported in patients independent of their body mass index (BMI)—even those classified as severely overweight or obese.
