On the other side of the coin, my always healthy dad did 6 weeks of physical therapy for hip joint pain that turned out to be cancer, which was immediately detected when they finally decided to perform a CT scan. He passed away almost exactly 1 year later at 46 years old.
I don't like this coin. Sorry about your dad.
Thanks, and I was trying to highlight the challenges of any situation like this. I do agree with the fundamental premise that we need to get better and deciding when to scan and coming up with non(or less) destructive techniques.
