Power walking could reduce the risk of aggressive prostate cancer: Men who can walk three miles an hour have a lower risk
* Men who walked fast before getting cancer have tumours with regularly shaped
blood vessels – these are less aggressive and easier to treat
* Men who walked at three miles per hour before diagnosis have 8% more
regularly shaped blood vessels than those who walked at 1.5 miles per hour
* The researchers think exercise could be equally beneficial for people with
other cancers
