“My goal is to find the best strategy for each individual patient I see, with the hope of providing the best balance of quality and quantity of life that I can.”

— Dr. Cassaday

What do you enjoy most about being an oncologist?

I wanted to be able to use my interest in science to help people in a meaningful way. I’ve found that balance as a hematologist-oncologist. Not only do I care for current patients with cancer, I also review past Fred Hutch patients to identify patterns that might predict how we can better treat future patients.

How does research play a role in your work?

Research is a critical part of my work at Fred Hutch, even though I don’t conduct any laboratory-based research. However, I collaborate with colleagues who do, and I apply their observations and discoveries to patient care. I am involved in several clinical trials testing new treatments for patients with ALL. Clinical trials really help move our field forward and, for some diseases, it’s how we meet unmet needs. However, I understand that a clinical trial may not be the right option for every patient.
