Hi Clairebax,
Welcome to the forum, but sorry about the reason you have come on due to your dads cancer diagnosis.
The fact it has spread to the bones means it is not curable, but it is treatable and there are people on this forum who are here many years after being diagnosed. It would be good if you could post your dads results, like his gleason score and PSA, it would allow people who may want to answer your post to give a more informed response.
I would imagine your dad will be put onto hormone treatment, which is usually administered every three months by an injection to the stomach area. This treatment can be very effective and can control the cancer for many years.
I know you say your mum and dad don't want to know the extent of the cancer in the bones, but they will be very frightened and the fear will make them not want to ask questions, as they fear the answer will not be good. If possible it would be good if you could accompany your dad on his appointments etc. so that you can ask the questions that need to be asked.
I presume your mum and dad are elderly, and all their generation probably new of cancer in years gone by was that if you got it you died and usually quite quickly. That is definitely not the case now, their are many tools in the box to contain this disease for many years, so you should try and reassure your dad if possible by letting him know this. There are people on this forum who have lived 10 or 15 years beyond diagnosis even when the cancer has been in the bones (metastasized).
If you want to talk to someone about this, please use the phone number at the top of this page and speak to one of the specialist nurses. They are absolutely brilliant, and will spend as much time on the phone with you as you need. They will be able to answer any questions you have and will also be able to reassure and comfort you.

Best wishes to you and your mum and dad, please keep us informed of how things are going.
Regards,
Gerry
