My psa floated from 3.9 to 5.2 and back for 8 years before finally going up to 7.6 in 6 months, and being cancerous as determined by the first biopsy. I now know that my doctor and I should have been paying closer attention to the increased levels way back 10 years ago when it was 3.0 or so and still rising. We didn't and I was very lucky that nothing worse happened before we decided to look further into it.
If it were me, I'd do the psa test each 6 months and pay close attention to the changes. From there, all you can do is repeat the biopsy with a 45 core sample test the next time, to saturate the gland with core testing if it keeps increasing. I know some will disagree, but the chances you will have cancer is greater than you won't have it, with these slowly increasing levels. The thing not to do is to breath a sigh of relief and relax/ignore the situation.
