Promote the progression of certain harmful bacteria in the mouth, stomach cancer, lung cancer, etc

Dec 16, 2024

Research has shown that certain harmful bacteria in the oral cavity are closely related to the occurrence of cancer such as stomach cancer and lung cancer.

The Apple Tree Medical Foundation (Chairman Kim Hye-sung) recently published a research paper on the association between oral microorganisms and malignant tumors including cancer in the latest issue of the Korean Society of Upper Gastrointestinal Tract and Helicobacteriology (December 2024 issue).

This study was conducted in collaboration with Daxmedi (CEO Noh Mi-hwa), a microbiome-based oral care company.



The results of this study are meaningful in revealing that certain harmful bacteria in the oral cavity not only affect systemic diseases, but are also closely related to gastrointestinal diseases such as stomach cancer and colorectal cancer, and gastrointestinal diseases such as pancreatic cancer and lung cancer.

The study compares research cases on microbial changes in the oral cavity associated with malignant tumors, including cancer, and suggests that it can be used as an early indicator of non-invasive cancer diagnosis and risk assessment by analyzing microorganisms in the oral cavity.



In particular, harmful bacteria such as Streptococcus anginosus, Fusobacterium nucleatum, and Veillonella parvula found in the oral cavity have been found to be closely related to the occurrence of malignant tumors, and these bacteria have been found to spread throughout the body through the esophagus, larynx and bloodstream to trigger immune and inflammatory reactions and promote cancer development and progression.

The study confirmed that oral health is not just limited to the management of teeth and gums, but an important area closely linked to systemic health, suggesting that regular oral care and early diagnosis technology will play a key role in cancer prevention and treatment.



We also identified its development as an important tool to assess and prevent the risk of cancer early if we understand the mechanisms of interaction between harmful bacteria and cancer and develop oral microbiological tests based on them.

Through this study, the Apple Tree Medical Foundation plans to re-examine the importance of oral microorganisms and develop more accurate diagnosis and prevention strategies by studying the relationship between oral microorganisms and systemic diseases in the future.
