@cekkk I'm 66 and my PSA has been above 6 for 3 years. The last reading was September 2023 and the reading was 10.03. I will be getting an updated reading next week since I will be seeing the urologist the following week. My urologist has not pushed for a biopsy but it may be because I'm not having any issues other than the elevated PSA. An ultrasound showed that the prostate is enlarged, which can result in a higher PSA. The urologist told me there are no imperfections in the prostate (via the DRE) and he uses that as the indicator for cancer. I trust his experience. You may want to get a second opinion before submitting to a biopsy.
