Major weight gains in adulthood could increase the risk a man won't survive prostate cancer. The reason behind the link is unclear, but the numbers themselves are very telling.
After following nearly 300,000 men, researchers say higher body mass index and weight gain since age 18 were associated with a higher risk of death from prostate cancer. As body mass index increased, so did the risk.
On the other hand, there was no association between weight and developing prostate cancer. Roughly a third of all American adults are considered obese.
