Common Mouth Bacteria Found to Combat Specific Cancers, Surprising Scientists and Promising Better Outcomes
Bacteria found in mouth, Fusobacterium, surprises scientists by killing certain head and neck cancer cells, leading to better patient outcomes.

A surprising discovery has been made by scientists, who found that a common type of bacteria has the ability to cause certain cancers to shrink. The bacteria, known as Fusobacterium, is commonly found in the mouth. Researchers expressed their shock at this finding and are now intensely studying the biological mechanisms behind this link. The study, which was conducted in collaboration with an international team of researchers, utilized various methods to investigate this phenomenon.
Unexpected Results of the investigation
The researchers' initial expectations were completely overturned by the results of the study. Previous research had actually linked Fusobacterium to the progression of bowel cancer. However, in the laboratory studies, the scientists observed a remarkable effect. When they introduced Fusobacterium to cancerous cells in Petri dishes and allowed it to take effect for a couple of days, they were astonished to find that the cancerous cells had significantly diminished. In head and neck cancer cells, there was a 70 to 99 percent reduction in the number of viable cancer cells after being exposed to Fusobacterium. Additionally, an analysis of patient data revealed that the presence of Fusobacterium in the cancer was associated with a 65 percent reduction in the risk of death compared to patients whose cancers did not contain the bacteria.
Positive Outcomes
The study also found that individuals with head and neck cancers containing Fusobacterium demonstrated improved outcomes. The researchers hope that these findings could have significant implications for the treatment of head and neck cancer, potentially leading to the development of new and more effective treatments in the future. Dr. Miguel Reis Ferreira, the senior author of the study, highlighted the potential impact of the findings on the treatment of head and neck cancer, stating that the presence of these bacteria within the cancer was associated with much better outcomes. He further emphasized that the bacterium demonstrated the capacity to eliminate cancer cells in cell cultures. Dr. Reis Ferreira also noted that efforts are underway to investigate the specific mechanisms through which the bacteria exerts its effects, with plans to publish a new paper on this topic in the near future.
Complex Roles of Bacteria
Dr. Reis Ferreira, a consultant in head and neck cancers at Guy's and St Thomas' and senior clinical lecturer at King's College London, stressed that the research has unveiled the complex role played by these bacteria in their interaction with cancer. While the findings suggest that the bacteria have the ability to cause head and neck cancer cells to diminish, it is essential to consider their established role in exacerbating other types of cancer, such as those affecting the bowel. The researchers are determined to further explore the intricate relationship between Fusobacterium and cancer to gain a more comprehensive understanding of its behavior and effects.
Implications for Treatment
The potential implications of this discovery for the treatment of head and neck cancer are significant. With relatively few therapeutic advances in this area of cancer over the past two decades, the newfound ability of Fusobacterium to influence the outcomes of head and neck cancer offers a promising avenue for the development of new and more effective treatments. The study's publication in the journal Cancer Communications has brought to light the potential of Fusobacterium as a positive factor in the prognosis of head and neck cancer, in contrast to its detrimental role in other types of cancer. The authors of the study emphasized the association between the detectability of Fusobacterium and improved overall survival as well as better disease-specific survival, further underlining the potential significance of these findings in the treatment of head and neck cancer.
Support for Research
The groundbreaking research, which was partially supported by Guy's Cancer Charity, has garnered praise for its potential to enhance the understanding of head and neck cancer and to pave the way for the development of more compassionate and effective treatments. The executive director of Guy's Cancer Charity, Barbara Kasumu, expressed pride in supporting the innovative research efforts and emphasized the aim of the research to improve the understanding and treatment of head and neck cancer. The collaborative nature of the research, involving contributions from international researchers, underscores the global significance of the findings and the potential impact on the treatment of head and neck cancer on a broader scale.
The discovery of Fusobacterium's ability to cause certain cancers to diminish represents a significant advancement in the understanding of the interaction between bacteria and cancer. The unexpected findings have opened up new possibilities for the treatment of head and neck cancer, offering hope for the development of more effective therapies in the future. As researchers continue to delve into the complex mechanisms at play, the potential impact of this discovery on the field of oncology and the treatment of cancer stands as a testament to the transformative power of scientific inquiry and discovery.
