You always need different opinions. It took me three different doctors to finally get the prescription for cancer screening due to family history. One would thing this kind of stuff is protocol but many times it is subjective, completely up to the doctor's opinion. For doctor 1 it may not be alarming enough and for doctor #3 crazy you didn't start the screenings 5 years ago. That was my experience, and this was at the same hospital network in the same city.
