Swallowing a sponge on a string could replace traditional endoscopy as an equally effective but less invasive way of diagnosing a condition that can be a forerunner of esophageal cancer. Barrett's Esophagus is usually diagnosed by having a biopsy during an endoscopy. This can be uncomfortable and carries some risks -- and it's not always practical for everyone who has symptoms like reflux and heartburn.
