Researchers have discovered that exercising at least 15 minutes a day may help reduce the fatality risk for prostate cancer patients.

The study was presented at the American Association for Cancer Research Frontiers in Cancer Prevention research conference, and scientists indicated that moderate levels of exercise can offer benefits to those fighting the disease.

Prostate cancer, which is detected through moderating , is a common cancer found in men aged 60 and older that can become fatal without treatment.

The researchers looked at the exercise levels of 2,686 patients. They found that men who engaged in at least three hours a week of exercises such as jogging, biking, swimming and playing tennis, had a 35 percent lower risk of mortality.

When it came to walking, men who walked four or more hours a week had a 23 percent less risk of dying than those who walked less than 20 minutes a week. Similarly, men who walked at a fast pace for at least 90 minutes a week had a 51 percent less risk than those who walked less than 90 minutes a week at a slow pace.
