Too easy... UofC is the major cancer center in the area and a good place to start your journey with your high PSA. You should have all treatment avenues available to you there short of going to Mayo, etc. If not, you will have to call around. The risk is minimal either way, no reason not to do what you need to do.

During the procedure, the doctor usually looks at the prostate with an imaging test such as transrectal ultrasound or MRI. Then they collect a sample of prostate tissue using a thin, hollow needle. This is done either through the wall of the rectum (called a transrectal biopsy) or through the skin between the scrotum and anus (called a transperineal biopsy). The doctor will usually take multiple samples from different parts of the prostate. Afterward, the tissue sample is analyzed in a lab to determine whether cancer cells are present.
