Exercise ‘may make tumours grow faster’

Now new research has shown that exercise may hasten the decline of some cancer sufferers.

Dr Lee Jones, of Duke University, said: “We found that among the mice that had the opportunity to voluntarily exercise, tumours grew approximately twice as fast as they did among the mice that did not have the opportunity to exercise.”

The scientists have cautioned that the results of the study may not be replicated in humans, and point out that heightened blood-flow can also be used to carry anti-cancer medicines into a tumour more effectively.
