No: If you go to ER they will not test for cancer. That is not the purpose of ER. See your regular doctor or an ear, nose and throat doctor.

No: The Emergency Room is for emergencies, such as appendicitis, heart attacks, car accidents, etc... A primary care doctor can look for cancer, and can refer to specialists for help (such as a gastroenterologist who specializes in the stomach and esophagus).

No: GERD and dysphagia is not an issue dealt with in the emergency room unless totally obstructed . Best to see GI physician to get an esophagram and do upper endoscopy which will resolve the issue.
