Exercising regularly can reduce cancer spread and recurrence, revealed a new study.
Researchers from the University of Copenhagen conducted a study on mice to understand how regular exercise involves in cancer reduction. The study was published in the Journal Cell Metabolism.
Mice with tumors were put on voluntary wheel training while another group of mice was the controls. The mice who spent time running on the wheel shrunk their tumors by 50 percent compared to their less active counterparts.
"As someone working in the field of exercise and oncology, one of the main questions that cancer patients always ask is: how should I exercise? Can we do anything? While it has previously been difficult to advise people about the intensity at which they should exercise, our data suggests that it might be beneficial to exercise at a somewhat high intensity in order to provoke a good epinephrine surge and hence recruitment of NK cells," said Hojman.
