Is a doctor a biologist

Yes, you most definitely do need to study physics during (or before) medical school. You may probably take it during pre-med, depending on the school or program you choose to follow. But physics is unfortunately a very important topic when considering medicine.

Physics is used in understanding partial pressures of gases, flow through tubes (bronchi and arteries, for example), and concepts related to blood pressure and resistance.

Other specialties use physics a lot more - orthopedics, opthalmology, and radiology come to mind.

I hate physics, too, but you need it. Sorry.
