I have elevated PSA for the least 6 years, 5.6, 5.9, 9.0.....12 and just recently 21. I had 2 biopsies done in 2009 and 2014, both benign. I have very hyperactive bladder urinating almost every 30 minutes and getting up at night 2-3 times. Never taken any medication for prostate or bladder etc. what should I do next to find out why the elevated PSA and treatment options. Thanks.
