Colon or colorectal cancer was known as one type of cancer triggered by unhealthy living habits, such as eating fatty foods, less fiber, less drinking, and rarely moves. However, two new studies find, this cancer is also triggered by certain bacteria.
Both studies were published in the journal Cell Host & Microbe reveal, the type of bacteria that can be found in the mouth can trigger an attack is highly colorectal cancer by manipulating the body's immune response.
The researchers emphasize studies on certain species of bacteria called Fusobacteria nucleatum. They had previously found, the number of bacteria in the mouth that many colorectal cancer patients. However, they have not been able to ascertain whether this bacterium is the cause of cancer.
In the first study, the researchers found, Fusobacteria the benign tumors in the colon can increase the potential of these tumors become cancerous. They also argue, that bacteria may be related to the initial formation of tumors.
Meanwhile, in the second study the researchers conducted experiments on mice that have been engineered to undergo colorectal cancer. They found, Fusobacteria increase the number of certain immune cells called myeloid cells. The cells can go into accelerating the formation of tumors and cancer.
Intestine is where the discovery of trillions of bacteria that is needed to maintain health. Bacteria affect the body's immune system which helps absorption of food juices.
Even so, these bacteria can sometimes trigger the disease so the experts to categorize bacterial intestinal bacteria into "good" and "evil".
The researchers believe their findings could provide the basis of the diagnosis and treatment of diseases better.
"Fusobacteria can trigger colon cancer, but more important is the discovery of new ways to stop tumor growth and spread," they concluded.
