Men who exercise often are less likely to die from cancer than those who 1 , new research published in the British Journal of Cancer revealed yesterday.
A team of scientists from the Karolinska Institute in Sweden looked 2 the effect of physical activity and cancer risk in 40,708 men __ 3 _ between 45 and 79.
The seven-year study found that men 4 walked or cycled for at least 30 minutes a day had a 34 per cent lower risk of 5 from cancer than the men who did less exercise or nothing at all. 6 the period studied~, 3,714 men developed cancer and 1,153 died from the disease. The researchers suggest that half an hour's walking__7__cycling a day increased survival among these men by 33 per cent.
The researchers surveyed men from two counties in central Sweden about their lifestyle and the amount of 8 activity they were usually doing. They then scored these responses and compared the results__9 _data on cancer diagnosis and death officially recorded in a central cancer registry2over a seven-year period.
Lead author, Professor Alicja Wolk, said: "These results clearly show for the first time the effect that very simple and basic daily 10 such as walking or cycling has in reducing cancer death risk in middle-aged and elderly 11 "
Dr Lesley Walker, director of cancer information at Cancer Research UK, said: "This study gives us a clear indication that men who exercise are less 12 to die from cancer, and that they are more likely to 13__the disease if they get it. It's not entirely clear from this study
what role exercise plays in preventing 14 in men, but we do know that a healthy lifestyle can prevent up to half of all cancers3-and 15 exercise forms a key part of this. "
