Good morning George.
My husband ha similar scores. 5.9 /3+4/localised. He originally opted, like you for AS but after a year had to choose a treament.
It wasn't such a choice for him as he was determined he wasn't having an op or long term radiotherapy so he also chose Brachytherapy. I have kept his profile fairly up to date and as it's like a diary it will tell you what he was feeling/experiencing as time went on.
It is almost a year since the procedure and apart from an urgent need to pee sometimes he is pretty well. He did have some real discomfort in the bowel area every time he peed or had sexual intercourse but that has eased off now and barely bothers him. He says it lasts a few minutes.
Like Lyrical says, click on the name under the profile and go from there.
Don't forget the Toolkit from the site. All the information is in one place and you can do comparisons from treatment to treatment. Go to main page, information, then publications.
Every man's treatment decision is his own. All you can do is weigh up the pros and cons of each treatment. Some men prefer to have the whole thing removed in the hopes that it all goes away and he can forget about it. It works for some, but not for others.
Not every man will react the same with the same treatment. My husband, for instance, didn't get the cystitis but I know that for some it is a problem.
Good luck with your decision. The only advice I would give is to not rush into it. Be as happy with your choice as you can be. You are the one that has to live with that choice.
Best wishes
Sandra
