How long will heartburn lead to cancer?

Heartburn itself does not cause cancer.

Heartburn is usually caused by acid reflux and erosion of the esophageal mucosa, causing damage to the esophageal mucosa. It can be seen in a variety of diseases, such as reflux esophagitis, peptic ulcer, achalasia, etc. Heartburn is generally a common digestive symptom, and the symptom itself does not cause cancer. However, if the patient does not treat the primary disease in time, heartburn symptoms can persist and occur repeatedly, which can cause repeated damage to the esophageal mucosa, which may lead to atypical hyperplasia of the esophageal mucosa, thus increasing the risk of cancer.
