It's great that you are posting, as your husband is starting a new treatment and I think you have come back to a great resource. Unfortunately, it is not me. I just want to tell you welcome and that the guys with all the knowledge will respond soon. Your husband's psa hike sounds to me like the therapy may not be working and your onc May need to switch, but I'm not the one to give advice. Gary's doc always tells us after a rise it may be "just a blip" but it never has been. When is his next test scheduled?
