It’s hard to be positive when you don’t know how you’re doing. The only way to know how you’re doing is to get professional surveillance. This is precisely why I see getting surveillance (scans and other imaging, tests, etc) as a positive. Even if something isn’t quite right, at least you know, your doctors know, and they can watch it or do something about it. They simply can’t do that if you’re not getting surveillance. This is precisely why it’s a positive thing, i.e. if you don’t get it done, you don’t know how you’re doing – that is a more worrying situation in my opinion.  Surveillance is meant in the widest context, it can range from a telephone appointing asking questions and getting answers, all the way through to scanning.
