[|Human|] hiI want to know if a perosn with prostate cancer treated 3 years ago with radiation IMRT/ IGRT and on hormone treatment since, now with rising PSA and metastasis in lungs , can adding bicalutamidew be the first line treatment or should we try chemo first?
[|AI|]  Hi, dairy have gone through your question. I can understand your concern. He has prostate cancer with metastasis in lung. It is stage 4 cancer, and he already took radiation treatment. You should try chemotherapy first. However, despite all treatment prognosis remains poor. Life expectancy is not good. Consult your doctor and plan accordingly. Hope I have answered your question, if you have any doubts then contact me at bit.ly/ Chat Doctor. Thanks for using Chat Doctor. Wish you a very good health.
