I have had prostate cancer for 10 years after a radical prostetectomy operation. During my post operative years, I have found that while taking asparin once a day, my 90 day review blood work shows a lower PSA than when I stopped taking asparin altogether. My Urologist goes only by standard treatment methods with no comment on asparin for or against it being beneficial to me. My doctor was so impressed that I had a PSA of .03 for years that he decided to experiment with me cutting off all medications to see how I made out. My PSA started to rise and never returned to its previous undetectable status. I have just started to take baby asparin again and waiting to see the results.
