I am 62 and have prostate cancer. It started the beginning of the year 2015. Earlier I use to make injection every 3 months in the stomach. I did Zytiga for 6, 7, or 8, months. Then I did Taxodere 8 sessions and just finished 8 sessions of Jevtana. My PSA is in the 70. My doctor wants to continue with JEVTANA. Your advise
