A new ten year study of almost 84,000 men in Hawaii and California found that men who put on extra weight after age 21 have significantly greater odds of prostate cancer. This is especially true for white males. Those who gained 10 pounds were twice as likely to develop advanced or aggressive prostate cancer than their slim peers. However, in black men the risk didn’t increase until the weight gain topped 25 pounds, but only for less aggressive tumors. These racial differences may be due to the different ways people store their excess fat.
PositiveTip: This study did not look at the benefit of weight loss on risk for prostate cancer, there are many good reasons to keep off the unnecessary pounds.
