Is there anything else I need to know about a barium swallow?
Your results may also show signs of esophageal cancer. If your provider thinks you may have this type of cancer, he or she may do a procedure called an esophagoscopy. During an esophagoscopy, a thin, flexible tube is inserted through the mouth or nose and down into the esophagus. The tube has a video camera so a provider can view the area. The tube may also have a tool attached that can be used to remove tissue samples for testing (biopsy).
