Medicine is even more weird with titles. At least in the UK if you get qualified people call you “Doctor” unless you’re a surgeon in which case you are called “Mr/Ms/Mrs/Miss/etc” unless you are a professor which some consultants are in which case it’s “professor”. But if you work in medicine and call a consultant surgeon “Dr <whatever>” they will actually correct you.
