Gum Disease and Cancer: Understanding the Risk
Gum Disease and Its Connection to Cancer
Research shows that gum disease bacteria can significantly elevate an individual's risk of developing head and neck cancers. A recent study revealed that more than a dozen bacterial species contribute to an alarming 50% increased cancer risk. Maintaining good oral hygiene habits, like regular brushing and flossing, may actually protect against this risk.
Study Overview
Conducted by researchers at NYU School of Medicine, the study tracked nearly 160,000 Americans over a span of 10 to 15 years, analyzing saliva samples to identify various oral bacteria.
- 236 participants were diagnosed with head and neck cancer during the study.
- 13 bacterial species were found to affect cancer risk, with an overall combined risk increase of 30%.
- Adding another 5 species often found in gum disease pushed this risk up to 50%.
Implications for Oral Health
Lead researcher Soyoung Kwak emphasizes the potential of these bacteria as biomarkers for future cancer risk assessment. Regular dental care could not just prevent gum disease but may also safeguard against serious health issues like cancer.
The findings were published on Sept. 26, 2024, in JAMA Oncology, further highlighting the need for vigilance in oral hygiene practices.
