A team of scientists from the Karolinska Institute in Sweden looked 【52】______ the effect of physical activity and cancer risk in 40,708 men aged 【53】______ 45 and 79.
The seven-year study found that men 【54】______ walked or cycled for at least 30 minutes a day had a 34 percent lower 【55】______ of dying from cancer than the men who did less exercise or nothing at all. 【56】______ the period studied, 3,714 men developed cancer and 1,153 died from the disease. The researchers suggest that half an hour"s walking 【57】______ cycling a day increased survival among these men by 33 percent.

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 【62】______ to die from cancer, and that they are more likely to 【63】______ the disease if they get it. It"s not entirely clear from this study what role exercise plays in preventing 【64】______ in men, but we do know that a healthy lifestyle. can prevent up to half of all cancers—and 【65】______ exercise forms a key part of this".
