Some strains of gut bacteria may increase the risk of bowel cancer, according to a study.
Scientists have found that people with more Bacteroidales bacteria are up to 15 percent more likely to get sick.
Charities have welcomed research, only the latest in a series of studies, to deepen the effects of the microbiome on health.
The microbiome – trillions of naturally occurring bacteria, viruses and fungi that aid digestion and disease control – is predominantly a product of genes.
May be slightly altered by diet and antibiotics, but the presence of Bacteroidales is more likely to
Volunteers have come from three separate studies that appear to reveal genetic variants that are related to gut bacteria levels.
He then gave this information to 120,000 people to see if there was a link between genes and cancer.
Results not yet reviewed by other scientists indicate that 13 DNA variants are associated with different intestinal levels of the intestine.  And people genetically predisposed to more Bacteroidales are between two and 15 percent more likely to get bowel cancer.
Dr. Caitlin Wade, senior author of the scientific paper, presented the findings of the NCRI Cancer Conference in Glasgow.
She said: "On average, people with this type of bacteria in their gut may have a slightly higher risk of bowel cancer than those who do not. "
But she added that it was" too early "to be sure because the relationship between the gut, genes and cancer is complicated.
And she called for more research to determine the type of Bacteroidales, for found to increase the risk of bowel cancer.
Professor Ian Tomlinson, incoming director of the UK Cancer Research Center, who did not participate in the study, welcomed the pioneering insight provided by the document.
said: "This is one of the first studies of using methods for provide insight into the causes of postulated and plausible – but largely unproven – links between the microbiome and gut cancer. "
WHAT IS MUMBLE CANCER?
Bowel or colon cancer affects the colon, i. E. which consists of the colon and rectum.
Such tumors usually develop from precancerous growths called polyps. Symptoms include:
- Bleeding from the bottom
- Blood in the stool
- Change in intestinal habits lasting at least three weeks
- Unexplained weight loss
- Extreme, unexplained fatigue
- Pain in the abdomen
Most cases have no clear cause, but people are at greater risk if:
- over 50
- Have a family with a history of the condition
- You have a personal history of polyps in your gut  Suffering from inflammatory bowel disease, such as Crohn's disease
- Keep an unhealthy lifestyle of
Treatment usually involves surgery and radiotherapy and chemotherapy.
More than nine in 10 people with first-stage bowel cancer survive five or more years after being diagnosed.
This falls significantly if diagnosed at a later stage.
According to UK bowel cancer data, more than 41,200 people are diagnosed with bowel cancer every year in the UK.
It affects about 40 per 100,000 adults annually in the United States, according to the National Cancer Institute.
