Can Acid Reflux Cause Esophageal Cancer?

Yes, long-standing acid reflux can raise the risk of esophageal cancer, but only in a small fraction of patients. About 10 to 20 percent of chronic GERD patients develop Barrett’s esophagus, and roughly 0.5 percent of those progress to esophageal adenocarcinoma each year. Early treatment changes that risk dramatically.

According to Dr. Ksheetij Kothari, an experienced Gastroenterologist in Pune and Advanced Endoscopy Specialist at Sahyadri Hospital, “Most patients with acid reflux never develop cancer, but the ones who ignore daily symptoms for ten or more years usually walk in late. Routine endoscopy catches most cases early.”

Acid reflux happens when stomach acid flows backward into the esophagus. Occasional reflux is common. Gastroesophageal reflux disease (GERD) is the chronic version, where reflux happens twice a week or more for several months.

The esophagus lining is not built for stomach acid. Repeated exposure causes inflammation and over time can trigger cellular changes called Barrett’s esophagus. About 10 to 20 percent of long-term GERD patients develop these changes, the strongest known precursor to esophageal adenocarcinoma.

Common GERD symptoms to recognise:

• Heartburn:Burning chest pain, especially after meals or when lying down
• Regurgitation:Sour or bitter fluid rising into the throat
• Difficulty swallowing:A feeling that food is stuck behind the breastbone
• Chronic cough or hoarseness:From acid reaching the upper airway at night

Early esophageal cancer often has no symptoms, which is why long-standing GERD patients benefit from periodic endoscopy. When symptoms do appear, they usually develop slowly and worsen over weeks to months.

• Progressive difficulty swallowing:Solids first, then soft food, eventually liquids
• Unintended weight loss:Losing more than 5 percent of body weight without trying
• Persistent chest pain:Pain behind the breastbone unrelated to meals or activity
• Vomiting blood or black stools:Suggests bleeding from the esophageal lining
• Hoarseness or chronic cough:When reflux or a tumour irritates nearby structures
• A change in heartburn pattern:Symptoms that suddenly worsen or feel different after years of being stable

One thing worth mentioning: if heartburn you have lived with for years suddenly feels different, that change matters more than the heartburn itself.

Not everyone with reflux develops cancer. A few specific factors push the risk up.

• Long-standing GERD:Reflux for 10 or more years multiplies the risk severalfold
• Barrett’s esophagus:The strongest known precursor, raising annual cancer risk to around 0.5 percent
• Obesity:Increased abdominal pressure pushes acid into the esophagus more often
• Smoking and alcohol:Tobacco roughly doubles the risk; heavy alcohol adds further harm, especially for squamous cell cancer
• Male gender and age over 50:Esophageal adenocarcinoma is far more common in men, especially after middle age
• Family history:A first-degree relative with esophageal or stomach cancer raises baseline risk
• Low-fruit, low-vegetable diet:Reduced antioxidant intake is linked to higher esophageal cancer rates

Most heartburn is harmless. But certain patterns deserve proper assessment, often with endoscopy. See a doctor right away if you have:

• Heartburn more than twice a week for over 3 months
• New difficulty swallowing solids or liquids
• Unintended weight loss of more than 5 percent body weight
• Vomiting blood or noticing black, tarry stools
• Severe or progressive chest pain unrelated to physical effort
• Persistent hoarseness, chronic cough, or sore throat for over 4 weeks
• Heartburn that suddenly changes character after years of being stable
