Pathologists

A pathologist is the physician who analyzes your tissue samples from tumors, lymph nodes and other areas and performs laboratory tests to detect whether cancer cells are present, and if so, the type of cancer. The pathologist provides information your care team needs to determine the very best treatment options for you. At Roswell Park, your samples are analyzed by pathologists who focus specifically on the diagnosis of cancers in the upper gastrointestinal tract.
