[|Human|] HiWhat is the best method to treat recurrent prostate cancer after undergoing  a radical prostatectomy  in1995. My PSA score is 4.1 and there is no metastasis. Which treatment is best, hormonal therapy orradiation therapy. The surgery took place 18 years ago.
[|AI|]  Hi!welcome to Chat Doctor! If prostate cancer recurs, follow-up treatment depends on what treatment you have already had, the extent of your cancer, the site of recurrence, other illnesses, your age, and other aspects of your medical situation. If the cancer is still thought to be localized to the area of the prostate, a second attempt to try to cure the cancer may be possible. If you've had a radical prostatectomy, radiation therapy may be an option, sometimes along with hormone therapy. When prostate cancer has spread to other parts of the body (including the bones), hormone therapy is probably the most effective treatment, It's often very effective at shrinking or slowing the growth of prostate cancer that has spread. Hope this helps you. Take care!
