Interesting and valid observations. However, there are no medical professional members (even if a doctor joined, he would have to keep postings to personal experience with his own PCa), and we do not profess to be a knowledge-base.
The primary focus is support, and we do that from our own experience, so it can't be anything but biased based on the overall membership experience.
There are those who preach just a bit too much (ok, some to extremes) on specific treatments, diets, supplements, and that causes me more headaches than you can imagine, and not just as a moderator. Sometimes that actually negates the support we should be aiming to give.
