[|AI|]  Hello, THX to contact us. I understand your concern. If I am your doctor I suggest you that it is suggestive of malignancy of prostate. PSA is Prostate Specific Antigen it is produced by the cancer cells of the prostate. So if their level is increasing it is necessary to do Trans rectal ultrasonography of the prostate. I will be happy to answer more of your concerns, kindly know me, Wish you a very good health at Chat Doctor. Chat Doctor. Infectious Disease.
