To be fair the human body is immensely complex. Every specialist will look at everything through the lens of their field, as at the very least they can rule out some things this way.
I had a doctor judge that my tonsils need to be removed, but for unrelated reasons I went to two other and both of them figured it's not as bad yet.
The difference between them was generational, as the first practiced an approach from 30 years ago, back when tonsils were indeed commonly removed.
