We can estimate your chances of cure accurately, and if you want to talk to your doctor about this, you should ask. We don’t mind answering these kinds of questions.
But even if we know a specific probability, such as 85% cured versus 15% not cured, we can’t know whether you’re in the 85% or the 15%. And no tests or scans that we can take right now will tell us either. Only time can tell us with certainty.
