Kathryn C. Arbour, MD

About Me

I am a medical oncologist whose practice is focused on caring for people with lung cancer. I have particular expertise in identifying patients who may benefit from immunotherapy or targeted therapy and incorporating these advanced therapies into their treatment plans. I am also actively involved in clinical trials to find newer and better ways to treat lung cancer.

People with lung cancer are often concerned with how their treatment will impact their day-to-day life. At MSK, our multidisciplinary team of experts is focused on effectively treating our patients’ disease in a way that helps them keep doing the things they love. Using the most advanced therapies in the field, we work together to design treatment plans that minimize side effects to make sure this can happen.

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.
