Why would they biopsy esophagus?
Esophagus cancers are usually found because of signs or symptoms a person is having. If esophagus cancer is suspected, exams, tests, and a biopsy (a sample of esophagus cells) will be needed to confirm the diagnosis. If cancer is found, further tests will be done to help determine the extent (stage) of the cancer.
