Get to Know 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.

What I Do at MSK

A thoracic medical oncologist is a cancer doctor who specializes in thoracic (thor-A-sik) cancers. These are cancers that have to do with the chest, including lung, tracheal (windpipe), and thymic (thymus) cancers.

It was a great experience, very professional and very detailed.

Mar 4, 2025

Dr. Arbour is that rare MD. who combines knowledge and intelligence and warmth and care. During the appointment we never felt rushed. My husband and I left her feeling we were in the best hands with the team of Dr Adusumilli and Dr Arbour.

Feb 27, 2025

Dr Arbour has been providing me with outstanding care for several years. Sh not only monitors my current health needs but incorporates preventative measures into my treatment plan. She also keeps me advised of decelopments in new medications which I find to be very reassuring. She has superior communication skills and both my wife and I always leave our encounters with her feeling that all my needs have been addressed and that I am in good hands.

Feb 25, 2025

Wonderful place and everyone was professional and pleasant.

Feb 25, 2025

Dr. Arbour is not only an excellent practitioner, she is also a thoughtful and empathetic person who listened to me and answered all my questions carefully and fully. I feel very secure in being her patient.
