Heartburn is one of the most common complaints in American doctors' offices, and most cases are a nuisance rather than a warning. But when acid reflux runs on for years, it can quietly alter the lining of the lower esophagus. That change, called Barrett's esophagus, is considered precancerous. Cleveland Clinic estimates that 10 to 15 percent of people with chronic gastroesophageal reflux disease (GERD) go on to develop it.
The everyday risk of Barrett's turning into esophageal cancer is low. MD Anderson thoracic surgeon Wayne Hofstetter estimates the progression rate at roughly 0.25 percent per year, and the American Cancer Society notes that most people with Barrett's never develop cancer. Still, catching the change early matters, because Barrett's itself is silent.
Why the condition often hides in plain sight
Barrett's esophagus produces no symptoms of its own. It is usually discovered when someone seeks treatment for long-standing reflux. That is the paradox at the heart of the disease: as the tissue changes, the burning sometimes eases up.
Dr. Daniela Molena, a thoracic surgeon at Memorial Sloan Kettering, has described how the pain can fade as the abnormal lining develops, which she says can be counterproductive because people then seek less help. The absence of pain is not proof that the reflux has stopped doing damage.

7 warning signs worth bringing to a doctor
The seven signs below are not a checklist that confirms Barrett's. They are the reflux-related symptoms that gastroenterologists at Cleveland Clinic, MD Anderson and Memorial Sloan Kettering flag as reasons to be evaluated, particularly if you have had frequent heartburn for years.
- Frequent heartburn that no longer responds to over-the-counter antacids. Persistent symptoms despite regular treatment can signal underlying tissue damage.
- Difficulty swallowing, or the feeling that food is sticking. Cleveland Clinic lists dysphagia among the symptoms of the underlying reflux disease that can drive Barrett's.
- Frequent regurgitation of food or sour liquid. A recurring backwash of stomach contents into the throat is one of the classic signals that the reflux is not under control.
- Chest pain that is not cardiac in origin. Reflux-related chest discomfort should be evaluated to rule out both heart disease and esophageal complications.
- A chronic cough, hoarseness or a lingering sore throat. Persistent irritation of the upper airway can point to acid reaching areas beyond the stomach.
- Unintentional weight loss. A drop in weight without dieting is a general warning sign that warrants a medical work-up.
- Vomiting blood, or black, tarry stools. These can indicate bleeding in the upper digestive tract and require prompt medical attention.
Who is most at risk
The typical profile is well documented. MD Anderson describes it as a white man over the age of 60 who is overweight. Cleveland Clinic adds that men are two to three times more likely than women to develop the condition, and that risk rises after age 55 and with a history of smoking and long-standing GERD. The American Cancer Society notes that about 9 in 10 esophageal cancers are diagnosed in people aged 55 or older.
What screening actually involves
Barrett's esophagus is diagnosed with an upper endoscopy, in which a gastroenterologist passes a thin, flexible camera into the esophagus and takes a small tissue sample. If Barrett's is present but shows no dysplasia (abnormal cell changes), both Cleveland Clinic and MD Anderson recommend repeat endoscopy every three to five years. When dysplasia is found, monitoring becomes more frequent and treatment options such as endoscopic ablation may be discussed.
If you have had frequent heartburn or acid reflux for five years or more, it is worth asking your doctor whether an endoscopic screening is appropriate for you.
