Cancer caused by MOUTH Bacteria

Healthy Mouth= Healthy Body! This is not the first time that research indicates that healthy oral bacteria equates to general wellness. This article says even CANCER is triggered by the balance of bacteria in the mouth. Low grade infections are common in the mouth due to poor dental care and abscesses within the bone. These not only overwhelm the natural immunity of our white blood cells, they also crowd out the growth of healthy bacteria. Follow your dentist’s advice–brush and floss morning and evening. Eat NATURE’S DIET as I have written about and take a probiotic or healthy bacteria after brushing. Open the powder into water and swish and swallow so the bacteria start to work in the oral cavity immediately.

Colorectal cancer may be triggered by mouth bacteria

(Medical News Today) Two new studies published this week suggest that a type of gut bacteria found in the mouth may trigger colorectal cancer by influencing the immune response and switching on cancer genes.

The researchers believe their findings may lead to more timely and improved ways of diagnosing, preventing, and treating colorectal cancer.

Our gut contains trillions of bacteria, vastly outnumbering our own cells. These microbe communities maintain our health by training our immune system and helping us digest food. But they can also trigger disease.

There is evidence that an imbalance between the “good” and the “bad” gut bacteria may promote colon cancer.

The two new studies, published in the August 14th online issue of the journalCell Host & Microbe, focus on a genus of bacteria called Fusobacteria, and the species F. nucleatum in particular.

Colorectal cancer is the second leading cause of death from cancer among Americans. Researchers have foundFusobacteria from the mouth are also abundant in tissues from colorectal cancer patients.

But until this latest research, it was not clear whether these gut microbes actually trigger tumors, and if so, how they do it.

In the first study, the researchers found Fusobacteria in benign tumors that can become cancerous over time. This might suggest that they contribute to the early stages of tumorformation.

Then, in mice bred to have a human-like form of colorectal cancer, the team found the bacteria sped up tumor formation by summoning a type of immune cell called myeloid cells, which penetrate tumors and trigger inflammations that can lead to cancer.

Senior author Wendy Garrett, of the Harvard School of Public Health and the Dana-Farber Cancer Institute in the US, told the press:

“Fusobacteria may provide not only a new way to group or describe colon cancers but also, more importantly, a new perspective on how to target pathways to halt tumor growth and spread.”

In the second study, another team found that Fusobacteria use a molecule that lives on the surface of the bacterial cell to stick to and then invade human colorectal cancer cells.

The molecule, called Fusobacterium adhesin A (FadA), switches on genes that spur cancer growth, triggersinflammation in the human cancer cells, and spurs tumor formation.

The team also found that tissue from healthy individuals had much lower levels of FadA than tissue from patients with benign and cancerous colorectal tumors.

Plus, they identified a compound that can stop the effects of FadA on cancer cells.

Senior author Yiping Han, of Case Western Reserve University School of Dental Medicine in the US, said:

“We showed that FadA is a marker that can be used for the early diagnosis of colorectal cancer and identified potential therapeutic targets to treat or prevent this common and debilitating disease.”

In another study of mice published earlier this year, researchers identified the mechanisms that help the good gut bacteria and the immune system to coexist. A group of immune cells called innate lymphoid cells (ILCs) seem to instruct the immune T cells to trust – that is, ignore – friendly gut bacteria, thereby allowing the immune system to maintain a friendly truce with these foreign entities.
