A recent study conducted by researchers at New York University (NYU) has found a potential link between poor oral health and an increased risk of developing head and neck squamous cell carcinoma (HNSCC), a common form of cancer in Europe. The study identified 13 bacteria species in the mouth that are linked to a 30% higher likelihood of developing HNSCC.
While factors like tobacco and alcohol use, as well as oral human papillomavirus (HPV) infection, are known risk factors for HNSCC, the study found that even after adjusting for these factors, the identified bacteria remained risk factors. The researchers emphasized the importance of good oral hygiene in reducing the risk of developing HNSCC.
Dr. Richard Hayes, a study co-author and professor at NYU’s medical school, highlighted the importance of brushing teeth and flossing not only for preventing periodontal disease but also for protecting against head and neck cancer. Dr. Claire Knight, from Cancer Research UK, emphasized the need for further research to explore the link between oral hygiene and head and neck cancer.
The researchers are now looking into how these bacteria contribute to cancer risks and how they can be prevented. In the meantime, individuals concerned about head and neck cancers are advised to reduce alcohol intake and quit smoking, as these are major risk factors for the disease.
The findings of this study serve as a reminder of the importance of maintaining good oral hygiene practices to potentially reduce the risk of developing head and neck cancer. Further research is needed to fully understand the relationship between oral health and cancer risk.
