Gum disease is linked to increased cancer risk in which sites?

• A. Head & neck cancer
• B. Pancreatic cancer
• C. Kidney cancer
• D. All of the above

Answer: (D)

Gum disease contributes to a persistent inflammatory state and potential bacteremia, which can influence cancer risk beyond the mouth. Evidence links periodontal disease with higher risk of cancers in multiple sites, including the head and neck region, the pancreas, and the kidney. While shared risk factors like smoking and diabetes help explain part of these associations, analyses that adjust for these factors still show a connection, suggesting an additional link beyond common risks. Inflammation and immune system changes driven by periodontal pathogens and their toxins can create a milieu that supports cancer development in various tissues. Because studies point to associations across several cancer sites, the best choice is all of the above.
