Gingivitis Bacteria Associated With Esophageal Cancer

Bacteria that cause gum disease, Porphyromonas gingivalis, frequently infect the esophageal tissues of patients with esophageal squamous cell carcinoma (ESCC), were associated with ESCC progression, and serve as a potential biomarker for ESCC. These results suggest that P gingivalis infection might be a risk factor for ESCC.¹
