In this case, the radiotherapy will probably be just one or two zaps of the bone mets to reduce pain, rather than a long process of regular sessions. RT for pain relief of bone mets is usually effective.
Have they changed his hormone or added a tablet called bicalutimide? It sounds like he has become hormone resistant (also known as androgen-independent or castrate-resistant) which means that the cancer has learned to survive without testosterone and is no longer being starved. Addinig bicalutimide can often hold things back for a few months or even a couple of years. Alternatively, they may suggest chemo and / or a new hormone such as abiraterone or enzalutimide, or Radium 223 which is particularly effective on bone mets.
Don't panic - once the pain is under control things will look brighter. Sometimes the hospitals struggle to get pain control right - a referral to your local hospice or a pain clinic might be useful.
Are you not able to go to appointments with him? If he gives his consent, the hospital can copy you into all letters to or about dad (for example, the treatment letters to GP, etc)

Thank you, i think the doctor talked about tabket and RT and theyre discussing the options at the appointment next week. His readings had increased over thr last 3 months also so hopefully the treatment will slow it down again. He has epilespy and spondilosis in the spine which makes it difficult for him to walk as it is so he is walking around the house with a stick at the moment. My brother is taking him next week with my mam so im going to see if he is going in witht them- i hope so.
