The new study says gut bacteria testing could be used to predict colorectal cancer

analysis of gut bacteria could be used to effectively predict colorectal cancer in different populations for early diagnosis and treatment of colorectal cancer, according to an international team of researchers.
report, published in the new issue of the British journal Nature Medicine, said the international team, led by the Camago Cancer Center in Brazil, analyzed genetic material from stool samples collected from 969 people in Germany, France, Italy, China, Japan, Canada and the United States. The subjects were made up of two groups of colorectal cancer patients and healthy people.
, the study found that the richness of gut bacteria in colon cancer patients was much higher than in healthy people in the control group. For example, the number of common oral bacteria called Ocythrobacteria was higher in patients than in the control group. Although it is not clear why the oral bacteria migrate to the intestines, Ocythrobacteria can cause inflammation of the intestines when it enters the intestines and is thought to be at risk of causing cancer, the researchers said. The researchers found 16 bacteria associated with colorectal cancer.
addition, the researchers found far more traces of choline triamcinoloid lysase in patients with colorectal cancer than in the control group, suggesting that choline metabolism in gut bacteria was associated with colorectal cancer. Choline is a nutrient found in red meat and other high-fat foods. When enzymes break down foods containing choline, it releases the carcinogen acetaldehyde.
" findings could help prevent colorectal cancer because the amount of bacteria in the gut can be controlled by diet. Emmanuel Diaz Neto of the Camargo Cancer Center explained. He said a high-fat diet could have adverse health effects because it could lead to an increase in the number of harmful bacteria.
colorectal cancer is the third most common cancer in the world. It is also the second deadliest common malignancy in women and the third fatality in men. If diagnosed in a timely manner, the cure rate can reach 95%. (Source: Xinhua.com/
