Oral Microbes Linked to Increased Risk of Pancreatic Cancer
Researchers at NYU Langone Health, in a study published in JAMA Oncology, have found that 27 species of bacteria and fungi in the oral microbiome are associated with a 3.5 times greater risk of developing pancreatic cancer. The study analyzed data from 122,000 healthy individuals and identified 445 patients who developed pancreatic cancer. The researchers discovered that the oral microbiome plays a significant role in cancer risk, and that certain species of bacteria and fungi can contribute to the development of the disease.
Key Takeaways:
- 27 species of bacteria and fungi in the oral microbiome are associated with a 3.5 times greater risk of developing pancreatic cancer.
- The study analyzed data from 122,000 healthy individuals and identified 445 patients who developed pancreatic cancer.
- The researchers discovered that certain species of bacteria and fungi can contribute to the development of pancreatic cancer, including bacteria that are already known to contribute to periodontal disease.
- The oral microbiome plays a significant role in cancer risk, and further research is needed to understand the mechanisms behind this relationship.
- The study found that by assessing the makeup of each participant's oral microbiome, scientists can estimate their cancer risk.
- The findings have implications for the development of new screening methods for pancreatic cancer.
- The study's senior authors, Jiyoung Ahn, PhD, and Richard Hayes, DDS, MPH, PhD, emphasize that further investigation is needed to establish a direct cause-and-effect link between oral microbes and cancer.
Statistics:
- 122,000: Number of healthy individuals whose data was analyzed in the study.
