If it were me, I would arrange for the Decipher test, https://decipherbio.com/ , to be part of the material collection when you have your biopsy in January so as to have a feel from the results, of aggressiveness. There are several genetic tests out there but I had MyRisk to look for brca gene and other gene issues that might affect my children or me.

I would also schedule a tele-health with a center of excellence a week or so after the biopsy so they can access the material and you get a second opinion.

Like many of us, knowing ahead of time that there is something there, allows you to spend some time looking at the different options for radiation machines and types of radiation plus removal options. That way when you talk to your doctor and he says radiation or removal...or AS, you will be able to ask some qualifying questions.

I may be a bit of an outlier here, regarding PSA, knowing that PSA is used as a guideline for next steps but my brother in 2022 had a PSA of 6.5 and around the same time, I had a PSA of 10.2. His risk level was higher as his had reached the lymph nodes. He had colon cancer 20 years earlier and was out of shape. He was treated with ADT and radiation. Then he got pancreatic cancer and passed a month or so ago. His was a complicated case. Mine was solved with radiation, no ADT and no spread even though my PSA was 10.2.

I question PSA alone and personally believe in catching things early and take multiple tests in a number of directions (Decipher, Genetic...) that can help you and your doctor, plus a second opinion doctor, if possible, make better decisions together for your treatment.
