Forty-five minutes of intense exercise three times a week may reduce cancer risk in patients with Lynch Syndrome, a genetic condition that can lead to cancer at a young age.
That amount of exercise made the immune system more able to stamp out cancer cells, researchers at the University of Texas MD Anderson Cancer Center found. The intervention — 45 minutes of high-intensity cycling 3 days a week — was specific by design, said oncologist Eduardo Vilar-Sanchez, MD, PhD, a professor of clinical cancer prevention and the study's lead author.
"We wanted to be very concrete on the recommendation," he said. "People don't adhere to vague lifestyle advice like 'just exercise.' We wanted to link a specific biologic effect to a very concrete intervention."
