Marc B. Feinstein, MD
Pulmonologist
My Role at MSKWe post reviews for MSK healthcare providers who have at least 30 patient experience surveys completed. If you do not see reviews for a provider, it may be because they do not yet have enough survey responses, or the provider may not be part of the group of healthcare providers included in the survey.
Only outpatient providers are included in the survey. Healthcare providers who only work in the hospital or in urgent care are not included in the survey. Pathologists or researchers who do not provide direct care to patients do not have reviews.

About Me
- Coordinator, Pulmonary Fellowship Clinical Research Program
My clinical expertise reflects an interest in lung cancer survivorship, but I am also interested in helping people who have incidental radiographic findings other than lung cancer. Many people who undergo chest x-rays or CT scans, for instance, learn that they have subtle abnormalities, such as small nodules, that are too small for biopsy.

While the vast majority of these abnormalities are not cancer, such findings still cause considerable anxiety when people know that there is something in the lung but don’t know what it is. For these people, I help decide which findings are suspicious and which are not. In doing so, I hope that those who have more worrisome findings can get their diagnosis efficiently and that others do not undergo any unnecessary tests or procedures.
I am interested in improving all phases of lung cancer management, including developing strategies for earlier diagnosis and guidelines to better manage symptoms among long-term survivors. With improvements in CT scanning and the advent of lung cancer screening, more and more people who have lung cancer are discovering their tumors earlier, when a cure with surgery is possible. For these people, I have worked with colleagues to create a lung cancer survivorship clinic.
Historically, lung cancer survivors have been an overlooked group of patients. Our lung cancer survivorship study group has been a national leader in describing challenges that survivors may face and what measures may be employed to manage them. We also intend to study medical and psychosocial problems that may develop in these patients, such as issues of sexual health, blame, stigma, and the fear of cancer recurrence.
