They found that exercise increased the chance of developing prostate cancer by five percent. But they wrote that they could not explain the connection.The researchers also found that people who did heavier exercises had a slightly higher rate of skin cancer. This, they say, could be from more sun exposure.Now, how exercise affects strokes.The more fit a person is in middle age, the less likely he or she will have a crippling stroke after age 65.This is the result of a new study by the University of Texas Southwestern Medical Center.Doctors studied 20,000 men and women between the ages of 45 and 50. They found that those who were most fit from moderate to vigorous exercise had a 37 percent lower risk of a stroke than those who were least fit.They say the lowered risk of a future stroke was present even when the subjects had other risk factors. These factors include high blood pressure and type-2 diabetes.The researchers of this study say they want doctors to not ignore low levels of exercise and fitness as risk factors for a stroke.This study was published in the latest issue of the medical journal called Stroke
