I am a radiation oncologist who specializes in treating people with lung cancer, including early-stage and advanced lung cancer, and cancer that has spread to other parts of the body. I see patients at the David H. Koch Center for Cancer Care at Memorial Sloan Kettering Cancer Center in Manhattan. I specialize in providing comprehensive treatment for lung cancer using external beam radiotherapy, a type of radiation therapy that uses high-energy radiation beams to destroy cancer cells in a tumor from outside the body.
