OK, you're right, and I have done this before. My bad. However, the inverse but highly relevant questions the patient asks are: Given that I got a positive result, what's the chance that I actually have cancer? Given that I got a negative result, what's the chance that I actually have it anyway? I could attempt this, but right now I have something else to do. Will check back later and probably find that someone's answered those!
