I had radiation therapy and seed implants after being diagnosed with prostate cancer. My psa was over 7. I have been taking lupron for the last two years and have four of the serious side effects enumerated on a medical web site. My last two psa's have been .02. My doctor wants me to continue on Lupron, saying Lupron treats prostate problems, not just the symptoms. Side effects include chronic urination, rapid weight gain, prolonged headaches, and painful urination. What to do?
