Cancer Risk Increases because of Gut Bacteria Imbalance

Cancer Risk Increases because of Gut Bacteria ImbalanceA new study has come up with findings that have implications for increased risk of bowel cancer because of an imbalance of gut bacteria. If researchers are to be believed, they found patients with the disease having fewer friendly bugs and more harmful bacteria when compared to healthy people.

The findings of the study have been reported in the Journal of the National Cancer Institute. Study leader Dr. Jiyoung Ahn, from New York University Cancer Institute, said, "Our findings are important because identification of these microbes may open the door for colorectal cancer prevention and treatment".

He said an important role is played by many thousands of bacteria live in the gut to regulate food digestion and inflammation.

The study saw researchers comparing the DNA of intestinal microbes in the stool samples of 141 bowel cancer patients and healthy volunteers.

The findings have revealed that the samples of patients had increased population of Fusobacteria. It is a common type of bacteria that is found in the mouth and gastro-intestinal tract, which is associated with gut inflammation.

Researchers are now looking forward to examine how these gut bacteria associated with colorectal cancer are affected by diet and lifestyle factors.
