Medical Oncology

“My goal is to combine compassion with the latest scientific breakthroughs to empower my patients in their cancer care. ”

— Dr. Tseng

What do you enjoy about practicing oncology?

One of the most rewarding aspects of being in oncology is the close link between research and clinical advances. Year by year, there’s more that I can offer patients — the standard of care constantly evolves, and new treatments and medications emerge. Much of what drew me to SCCA were the clinical research opportunities at the Fred Hutch/University of Washington Cancer Consortium. The consortium gathers experts from Fred Hutch, University of Washington, SCCA and other partner organizations to accelerate scientific breakthroughs. It’s a remarkable opportunity to translate discoveries into new and better treatments for my patients with lung cancer.

What’s it like to work with you?

I approach every patient the way that I would want my own family members to be treated. I made that promise to myself a long time ago, and I come to work every day fulfilling that promise. I pair every patient’s unique goals and circumstances with the latest scientific advances in order to provide a personalized approach to care. Being a part of each patient’s journey is incredibly meaningful to me.

Provider Background

Specialty: Medical Oncology

Area of clinical practice

Head and neck cancers, thoracic cancers

Lung cancer, head and neck cancers

I am a board-certified medical oncologist who specializes in the treatment of lung cancer, head and neck cancers, mesothelioma and thymic cancer. In addition to providing clinical care, I have over a decade of scientific experience in cancer immunology, a field of study that examines the relationship between the immune system and cancer cells. Our immune system has evolved to respond to viruses and other pathogens, and it’s only recently that we’ve harnessed the immune system — in the form of immunotherapies — to target cancer. My primary research interest is investigating what factors drive individual responses to immunotherapies so that we can give every patient the best possible chance in their fight against lung cancer.

Clinical Trials

We make promising new treatments available to you through studies called clinical trials led by Fred Hutch doctors. Many of these trials at Fred Hutch have led to FDA-approved treatments and have improved standards of care globally. Together, you and your doctor can decide if a study is right for you.

View Clinical Trials


Many of our Fred Hutch doctors conduct ongoing research to improve standards of patient care. Their work is evaluated by other doctors and selected for publication to the United States National Library of Medicine, the largest medical library in the world.
