Engaging in physical activity regularly may help to boost an individual's defenses against cancer.

This research work studied the correlation between being physically active and the probability of developing cancer in a study population comprising of over 26,000 Canadian men and women. Researchers followed all the participants for a duration of 15 years. 

Researchers noticed that the higher the level of physical activity, the lesser the chances of developing cancer. This study shed more light on the beneficial role regular exercise play in the prevention of cancer.
