I am a radiation oncologist who cares for people with lung, head and neck, and gynecologic cancers. I specialize in intensity-modulated radiation therapy and image-guided radiation therapy. I am also an expert in stereotactic body radiation therapy. This treatment allows for shortened treatment times thanks to higher doses of radiation. I see more than 300 patients a year. For general information, call Memorial Sloan Kettering at 212-639-2000, 24 hours a day, seven days a week.
