A Japanese study published in the journal Nature Medicine indicates that the analysis of the intestinal flora would make it possible to detect colorectal cancer at the lowest stage.
The Osaka researchers used the stools of 616 patients after a colonoscopy. They analyzed their microbiota to understand how to detect signs of colorectal cancer earlier.
Changing microorganisms in tumors
The study highlighted a change in six microorganisms in patients who carried a malignant tumor of this type of cancer. However, if the microbiota changes if there is a tumor, identifying these microbial markers could make it possible to detect the presence of colorectal cancer much earlier than with the techniques currently available to us.
The researchers explained that colorectal cancer is on the one hand genetic, but also of microbial origin. Moreover, from the early stage of the disease we notice an increase in bacteria: Atopobium parvulum and Actinomyces odontolyticus. Later, other bacteria develop: Fusobacterium nucleatum, Gemella morbillorum, Parvimonas micra.
