When I was a kid, our Dentist called months after I had been in for a cleaning and told my parents that he had been reviewing old x-rays and noticed 1-2 cavities on my teeth that they had not spotted earlier.
Even back then as a kid, it struck me that he could just be making this up because he needed more money. But there is no way to test this without going to the expense of another doctor for more x-rays.
For some reason, I’ve always remembered this.
Just recently, another friend had age-related, routine, diagnostics done at a special medical center and was told there were concerns leading to more tests, a procedure and then more tests out into the future all at substantial expense but all leading to no serious issue found. And then this person had two more friends have the same diagnostics, at the same place, leading to the similar results and test and again with no issue found.
We are so scared of the C word that we jump through every single hoop to test, evaluate, diagnose and re-test. Our fear of the C word is fully justified as we all have stories. However, that fear makes us very vulnerable to fraud, wasted time and money, possible harm from the tests themselves and then, of course, fake miracle cures.
I do not know the solution to this problem other than to ask around when needing professional help in any matter (doctor, accountant, lawyer, etc.), seek 2nd opinions on serious matters, and try to remain calm and wise in your decisions.
Regarding the Dentist, I vaguely recall that we didn’t stay with him much longer. Can’t even recall if we went back to have those ‘cavities’ filled. That same Dentist once was needing to remove a tooth in my mouth and he deadened the wrong side of the mouth and was about to start cutting before I stopped him.
