A hospital is a healthcare facility that provides inpatient and outpatient diagnostic, treatment, and palliative care services. It may serve a community or regional population or serve as a teaching and referral center. A hospital may seek approval for its cancer program from the American College of Surgeons Commission on Cancer, whose program standards require operation of a hospital cancer registry.
