You might want to ask your PCP to order a PSE test from Oxford Biodynamics. It's a blood test that boasts a 94% accuracy of how likely, or unlikely, your husband is to have prostate cancer based on looking at biomarkers. It is used to decide if a biopsy is needed or for recognizing a biological re-occurrence. They say that a PSA test alone is 55% accurate. Here is their product web page:

If you do an MRI and/or biopsy, you might want to also do a telehealth with a center of excellence.
