I myself had a severe prostate condition. I did not bother to have it diagnosed since I know what the medical outcome would be.
I treated it successfully with the Beck devices from Sota Instruments. I suggest you follow the protocols faithfully to get the full benefit. I also know another gent who was formally diagnosed with prostate cancer and used these devices to obtain remission.
h2o2 will also be of benefit. Just as an experiment you might try soaking a cloth in 50% diluted 3% food grade and applying it to the groin area. Others have reported very good uptake with this method and it has the advantage of being applied directly to the effected area.
I would also advise addressing colon health as I believe this has particular relevance to prostate conditions.
