Patients suffering from frequent heartburn or acid reflux are at a higher risk of developing esophageal cancer. According to the National Cancer Institute Center for Cancer Research, esophageal adenocarcinoma, the most common form of esophageal cancer, is often linked to a condition called Barrett’s Esophagus, which is believed to affect about one percent, or approximately 3.3 million, of people in the U.S. Esophageal cancer is often not found until it is advanced, but it can be treated successfully if it is found early through screenings. Early detection saves lives, and this screening technology can identify pre-cancerous cells that can be effectively eradicated.
