Is it possible for esophageal diverticulum to become malignant?

Esophageal diverticulum may be malignant.

Esophageal diverticulum is a pouch tissue formed after esophageal wall bulging, which is easy to retain food. Under normal circumstances, this disease is a benign disease, patients are prone to eating difficulties, food reflux and other symptoms. However, because esophageal diverticulum retains food for a long time, it may form inflammation, ulcer, etc. After repeated attacks of inflammation and ulcer, because epithelial cells are constantly destroyed and repaired, it may cause cell gene mutation, which may promote malignant change. Although the risk of esophageal diverticulum becoming malignant is relatively low, patients should be treated promptly to intervene in the disease.
