I do believe what Paul said--it all depends on each person's specific circumstances. I think the main reason my Dad wouldn't get on here is because he doesn't want to be comparing his situation to any one else's. He is the type who doesn't like to "take people's word" for things. He just has to try something out himself before making a decision. And, like I said, it isn't that he is 100% against having one--he just wants to try to get through this treatment without one. Just one less procedure for him to go through and one less thing for him to deal with. He starts back up with radiation today. 3 weeks left. I'll let you know how it's going.
