I recently had a PSA test that resulted in a value of 8. Consequently, this was followed by an MRI, giving a PI-RADS score of 4-5. I then had a biopsy, but was surprised to hear that the results were negative. I would like to know how common this is. Should I be worried that the biopsy missed something?
I've been told to have the PSA rechecked periodically, and to have more tests if it reaches 12. But how long should I wait?
