Yes, over time, acid reflux can indeed lead to cancerous growths.

Gastro-Esophageal Reflux (GER)?

Acid reflux, also known as GER (gastro-esophageal reflux), begins when stomach acid rises up with food. The digestive juice, or acid, may irritate the lining of the esophagus, which is the tube that carries food from the mouth to the stomach. This irritation is exhibited by a burning sensation felt in the throat or chest of the affected person. However, children under twelve years of age with GER may not experience heartburn, but instead exhibit vomiting, coughing, and respiratory problems.

Gastro-Esophageal Reflux Disease (GERD) 

On-going (more than twice per week) acid reflux, or GER, can be classified as acid reflux disease, otherwise known as GERD (gastro-esophageal reflux disease). Inevitably, persistent GERD will cause scar tissue to form as a result of the burning stomach acid coming up into the esophagus.

Barrett's Esophagus 

Over time, the scar tissue cells may take on an abnormal shape and color; this condition is known as Barrett’s esophagus. The abnormal shape and color of the esophageal cells can also indicate gastro-intestinal cancer, which is why people who have GERD, or experience symptoms of GERD, need to be followed closely by a physician. A physician may put a treatment plan in action to prevent cancer from occurring.

A treatment plan may involve life-style changes, medications, and/or surgery. Life-style changes may include the following: stopping smoking, avoiding acid producing foods and beverages, losing weight if needed, wearing comfortable clothing (not tight), eating two-three hours before lying down, and sleeping with your head elevated. Medications and/or surgery may not be necessary if life-style changes alone prove effective.
