Which Prostate Cancers Need Treatment?

The very common Gleason 3+3=6 prostate “cancer” is NOT a health-risk because on both clinical and molecular biology grounds, the Gleason 3+3=6 disease LACKS the hallmarks of a cancer. http://www.ascopost.com/issues/june-10-2016/prostate-cancer-opinions-vary-on-gleason-scores-and-surgery/
Shamefully, the Gleason 3+3=6 “cancer” label has been retained to have you believe that it has the same potentially lethal risk as high-grade prostate cancers. http://www.ascopost.com/issues/december-25-2016/a-gleason-6-tumor-is-it-cancer-and-should-it-be-treated/
Only the less-common high-grade prostate cancers demand detection and treatment as
only the high-grade prostate cancers are a health-risk and potentially lethal. Only this category of prostate cancer is connected to prostate cancer death statistics.
Although prostate cancer is the second most common cancer in men, most of these cancers are NOT a health-risk and only 3% of men diagnosed with cancer will die from their disease. The other 97% will die from another cause.
