Picco, welcome to you and your family. Raddad had thrown out a help request in another thread for you, hopefully the radiation guys will address your concerns soon.
I can offer some info. for you. You asked if you could do radiation first, then surgery if needed. That approach is seldom used, I think we might have one person here who did that. The surgeons don't want to operate on radiation treated (damaged) tissue, as it tends to have adhesions, and sort of 'melts' together to surrounding tissues, glands and support structures. There is a great danger of damage to the colon wall, as they share a common boundary with the prostate bed and support structure. In the US, there are surgeons who would attempt that, but they are few and hard to find.
Finding a surgeon in AUS who will operate, after reading of your husbands past problems may be tough. I suspect it will take the approval of the entire surgery team- maybe even the medical review board of the hospital-, after careful review. The aneastelogist (SP) along with the surgeon will have to decide that one. However, you don't know that until you ask, don't give up or rule that option out yet.
As you will find out, if the tests are scheduled, then you do have time of make a reasoned and well-studied decision. The options for radiation are with seeding or without, with hormone therapy or without, intermittant or long term. Several options available, plus some others that may or may not be available in AUS. So there's no shortage of decision to make. Remember, contrary to first instinct, you two aren't approaching the end of a path, but have only begun a walk down it, with a long journey ahead of you. Study, ask questions- as many as you need to- here, discuss with your husband and possible medical team members, and decide.
I would encourgage your husband to join us here, at least to read this thread, as well as others. He may not be able to speak, if he can peck out the letters, then he can join us here. Hope this has helped some, and that others will quickly find their way here to help out.
