John N. Allan, M.D.

The quiet corner of 70th and York houses a specialist who guides many through cancer care. John N. Allan, M.D. practices at the Starr Pavilion, a familiar landmark on the Upper East Side. Solid tumors, hematologic cancers, and complex cases often arrive here first. They also see patients for second opinions when prior treatment paths have stalled.

Oncology services span chemotherapy, immunotherapy, and targeted drug regimens tailored to each patient’s disease profile. Radiation therapy coordination and surgical planning play supporting roles when needed. Survivorship clinics focus on life after cancer, monitoring long-term effects and quality-of-life adjustments. Clinical trials open doors to experimental treatments not yet widely available elsewhere.

The building sits at 520 E 70th St #3F in the mid-block stretch between York and East End Avenue. Patients and families navigate the doorman-accessible lobby before the elevators rise to Suite 3F. A short walk from Lenox Hill Hospital and Weill Cornell campus, the location anchors a busy corridor of medical offices.
