When my husband was diagnosed, Sept 2011, with stage 4 prostate cancer his PSA was over 5000.
He Urologist started him on Casodex which gave my husband relief for the constant bone pain within two days. Shortly thereafter Eligard injections began. Jan 2013 he had an Orchiectomy to do away with the painful injections.
Today his PSA is 8.7 (it had dropped to 0.3) and doing the watchful waiting, without any medications. Currently he is symptom free but the Oncologist believes its a matter of time before the cancer returns.
