The treatment itself sounds excellent and his results so far are very encouraging. Only YOU really know if your father is up for 26 radiation treatments. The treatments themselves are easy - 10 mins on the table; it’s the bladder and bowel prep that can be a challenge.
You need a very full bladder and sometimes they run behind schedule and you need to hold it for a longer time. If Dad can do that ( not wearing pads or diapers now or has some incontinence) he’ll be fine. The bowel prep is just a ‘no gas’ diet that was a challenge for me (love my fiber!) but maybe not for your father.
The drugs are probably the biggest wild card, as they do have side effects. The Orgovyx not so much but the other two need to be watched very carefully.
Nobody has a crystal ball, but Dad may have 10 more years in him and treatment will give him that. Or maybe he would live another 10 with no treatment - blasphemy to even say that🤫- but we’re all different.
My friend’s father passed recently (in his80’s) and he was very active. One day he had a pain and then was dead a week later. The docs told my friend that his dad had cancer everywhere - every organ, every bone, you name it. Never even tried to figure out what kind of cancer it was.
My friend was at peace with this turn of events because his father was never subjected to any medical treatment, lived a great life, and then passed peacefully in a week on pain meds.
You, my friend, are not as lucky because you KNOW your Dad has a problem and now it’s up to you to decide…. “TAG, YOU’RE IT!!”🫣
