An interesting quote by a famous Canadian doctor, Sir William Osler, and I do believe there is some truth to this,
“It is much more important to understand what sort of person has a disease than what sort of disease a person has.”
Fun fact: William Osler’s father, Featherstone Lake Osler (1805–1895), the son of a shipowner, was a former Lieutenant in the Royal Navy. In 1831 Featherstone Osler was invited to serve as the science officer on Charles Darwin’s voyage to the Galapagos Islands, but he turned the offer down because his father was dying.
Another fact: Although a decorated physician and even considered by some as the “Father of Modern Medicine”, Osler was “in support” of bloodletting, which is now a largely abandoned practice and considered pseudoscience.
