Medical Specialties that use / require math?

I'm currently a chemical engineering / applied math double major, and just finished my 2nd year of undergrad. I've always wanted to become a doctor, but I really love math and am afraid I will not be able to apply it as a doctor. Are there any specialties that use math or complex (math-like) problem solving frequently? I've heard radiology has some math, but I've been pressed to find exactly what it entails lol. Toxicology is governed by differential equations, do practicing toxicologists... Medical Specialties that use / require math?
