No, it's not just the internet. Over the years I have read 3 or 4 books about prostate problems written by urologists. They are doctors just as much as your doctor is a doctor.

I even remember one of them stating that riding a bicycle can raise your PSA. The American Cancer Society, in their cancer journal, states that there is a corelation between dairy and the agressive form of prostate cancer. Will you ever hear your doctor mention any of these things? No! It's not their job to educate you. Their job is to diagnose and treat. So good luck to you if you are relying only on what your doctor says.
