65 yo, in good health, active. I've had BPH and mild cessation incontinence ~2yrs. Semiannual PSA tests have been 2.2-3.8, very weak upward trend. MRI last April was neg.
Latest reading was 4.5 ng/ml, free PSA 9%. First time urologist has mentioned free PSA. He recommends another MRI in April '24. Consensus guidance seems to be that biopsy is indicated if free PSA <10%. Is there reason to wait?
