NPR Science Friday - Coffee and Prostate Cancer

This is a nice discussion of the new research suggesting that coffee consumption provides significant protection against prostate cancer in men. One of the artifacts from the research is that men who drink the most coffee (therefore getting the most protection) also had higher testosterone levels than those who drank less coffee or none at all.

Hopefully, this will begin to put to rest the false belief that higher testosterone levels cause prostate cancer. From what I have seen, it is estrogen rather than testosterone that causes the cancer. And previous studies that linked T levels to cancer did not look at the conversion of extra T into estrogen, which may be where the false link comes from. Limit the conversion of T to estrogen, which is done by the aromatase enzyme (and can be prevented or limited aromatase inhibitors such as Anastrozole (Arimidex), Formestane (Lentaron), and some OTC supplements), and you can limit the occurrence of the cancer.

Scientists this week said that they had found a link between increased coffee intake and decreased prostate cancer risk in men. The finding came out of an NIH-funded study of 50,000 men. "Avid coffee drinkers," those who consumed six or more cups per day, had 60 percent lower risk of aggressive prostate cancer than men who drank no coffee. The results of the study were presented this week at the American Association for Cancer Research meeting in Houston. The researchers said that it was too early to say which, if any, of the thousands of chemical compounds in a cup of coffee was responsible for the effect. We'll find out more.
