My Dad is facing decions about further treatment. He has had a protectomy (7 mos. ago), radiation (8 weeks ago) and his PSA has been rising.It is 4.1 now, and said to be quite agressive cancer. Lupron or castration are options that are being recommended at this time. He is seeking information about these options, and is concerned about osteoporosis, and other side effects of the Lupron. Would you share with me, please. I would welcome any input you may have.
