James Fetten, MD

About Me

I am a medical oncologist with more than 20 years of experience who specializes in caring for people with head and neck cancer. I began my oncology career by training at Memorial Sloan Kettering, after which I practiced in upstate New York. I served as Chief of Oncology for a major health system and was president of the local county medical society. It  was a privilege to come full circle and return to MSK to focus on head and neck cancer. My practice is located at the 64th Street Outpatient Center, in Manhattan, as well as MSK Westchester.

I have expertise in developing and implementing treatment plans that include chemotherapy, immunotherapy, and targeted therapies, or some combination of these. I work with each of my patients and their families to map out a strategy for achieving optimal results best suited to their needs. My philosophy is that caring for people with cancer requires commitment, compassion, and a personal connection for a journey that is undertaken as a doctor-patient team.

I am also interested in the role of lifestyle during cancer treatment and survivorship, particularly physical activity and nutrition. I first developed this interest while participating in a 3,300 mile, cross-country cycling event called Tour of Hope to raise awareness about cancer and research. I rode alongside cancer survivors and caregivers and was inspired by the way they could derive a positive experience by incorporating physical activity into their cancer journey. I used this experience to start a physical activity program in upstate New York for cancer survivors centered around cycling and I am still an avid cyclist myself.

Most major health insurers offer plans that include MSK as one of their in-network providers. If MSK is in-network, it means all our doctors are too. Medicaid and New York State Medicare also provide benefits for care at MSK.
