What is a Physician Assistant?

  • “PAs play a crucial role in expanding access to health care through their collaborative partnership with supervising physicians. As licensed health care providers, they can acquire medical histories; perform physical examinations; order, perform, and interpret diagnostic and therapeutic tests and procedures; prescribe medication; and provide medical education and counseling. This assistance enables physicians—who are in great demand—to care for more patients. PAs work in all the medical disciplines and may be found practicing medical oncology, surgical oncology, or radiation oncology, providing care to patients of all ages.” AOCS citation.
