Research from National Institute of Cancer indicates that while excess weight may not be a causative factor for prostate cancer, there is a great chance that obese men are more likely to die of the condition. Study was conducted over 5 year duration.
While obesity did not impact the risk of developing prostate cancer, obese men were 46 percent more likely to die of the disease, while thin men were 25 percent as likely to die of cancer.
Lower levels of testosterone in obese men were linked to reduced risk of developing the cancer, while higher levels of insulin-like growth factor-1 in obese men helped the rapid progression of cancer resulting in death.
Obese men with prostate cancer are more likely to have aggressive tumors and to experience cancer recurrence after surgery compared to men of normal weight.
