A Simple Test Could Tell You!
Cancer researchers from Johns Hopkins have concluded that some patients may develop colon cancer due to two specific digestive bacteria that form a film on the colon. According to the study paper, which was published December 2015 inScience magazine, these two types of bacteria invade the protective mucous layer of the colon and create a small ecosystem, including nutrients the bacteria need to survive, causing chronic inflammation and subsequent DNA damage that supports tumor formation. These findings also seem to add to the growing evidence that gut bacteria is more influential on our immune system than we may realize.
The two bacteria the doctors found are known as Bacteroides fragilis and Escherichia coli (or E. coli). The B. fragilis strain, called ETBF, appears to cause inflammation in the colon, while the E. coli strain causes DNA mutations.
Also, the bacteria was linked to patients without a family history of colon cancer. Cancers such as these–where there is no genetic tie–are known as sporadic cancers. Only 5-10% of cancers are considered heredity, meaning the remaining 90-95% are considered sporadic.
