Hi @harley52, I've added your post to the Men's Health group (https://connect.mayoclinic.org/group/mens-health-1/) as rising PSA levels are often discussed in this group. Prostate cancer is not the only cause of rising PSA levels. Here's a good article that explains other potential causes such as age, prostatitis, certain medical procedures, benign prostatic hyperplasia (BPH), urinary tract infection, and others.

If cancer has been ruled out, has you doctor tested for any of the other possible causes?
