Dr. MatthewMcMillan

Dr. Matthew McMillan, MD, is a radiation oncologist at Memorial Sloan Kettering Cancer Center (MSK), where he specializes in the treatment of lung cancer, gastrointestinal cancers, metastatic disease, and bladder cancer. He sees patients at MSK Commack on Long Island and at the New York Proton Center in New York City. Dr. McMillan earned his medical degree from the University of Michigan, where he received a national research fellowship from Alpha Omega Alpha and graduated with Distinction in Research. He completed his radiation oncology residency at MSK, where he also served as Chief Resident before joining the faculty. His clinical focus is on matching each patient with the safest, most effective radiation therapy plan, whether that involves proton therapy, stereotactic body radiation therapy (SBRT), or other advanced techniques. He applies particular expertise to ultra-central lung tumors, which are situated close to critical structures in the chest and carry a heightened risk of radiation-related side effects, often incorporating proton therapy to better protect surrounding healthy tissue.
