[|Human|] my father is suffering from prostate cancer stage 4. recent ct scan shows it growing towards bladder and rectum.  he already had orchidectomy 1 and 1/2 yr back and was on flutamide, was respoding well until recently. his psa is 15 and his histopath was poorly differentiated adenocarcinoma
[|AI|]  Hi, Thanks for writing in. The PSA is calculated from baseline before treatment. A level of 15 is high but not too high. Stage 4 cancer prostate can have survival of more than 2 years with recommended treatment. Surgery cannot be done and other forms of treatment needs to be thought of. It will help to discuss chemotherapy and radiation therapy with the oncologist and plan the treat. Pain relief is most important for him and this should be stressed up on. Please see that he gets enough pain relief and depending on the discomfort he is given medicines adequately. The bladder function also requires assessment, and please see that he does not develop urinary infection which can get complicated. Please do not worry.
