Men who are overweight have a higher risk of the lethal form of prostate cancer. And for those who are bees, the risk is even higher.
The Research: A meta-analysis (a study combining several studies) examined 1.2 million initially cancer-free men. While being overweight did not increase the risk of prostate cancer overall (including quiet/indolent type and the more lethal forms), it did increase the risk of the lethal prostate cancer. The same observation is true of smoking: While it does not increase the overall risk of prostate cancer, it does increase the risk of the potentially lethal form.
My Take: Being overweight may increase the chances of prostate cancer spread via boosting of inflammation and raising levels of growth factors. Some of the factors that drive cancer metastasis (spread to distant sites) appear to be different than than those that cause prostate cancer. Keep moving (aim for a minimum of 150 minutes per week of the equivalent of a brisk walk), and don’t smoke! I’m Dr. Michael Hunter.
