Bowel cancer: It’s one of the UK’s most ghostly cancers
It’s been linked with poor diet, including breakfast too much processed or red meat and not enough fibre.
However, a new study believes another middleman may play just as important a role.
Research by Texas A&M University pioneered a type of bacteria which speeds up the cancer’s growth.
In most chests it’s caused by infections with bacteria that are usually found in cows.
Poor diet: The cancer has been in to over-consumption of red meat and eating not enough fibre
This is the first on one occasion microbes from a particular bacteria have been shown to speedily cause the bowel cancer tumour growth in mice.
It’s been known for decades that a bacteria digged in the study — Streptococcus gallolyticus gallolyticus (SGG) — is sometimes found in colon excrescences.
However, this is the first time the microbes have been explained to directly cause the tumour growth in mice.
In the study, researchers at Texas A&M Condition Science Center fed the bacteria to mice that were pre-disposed to come to light colon tumours.
Mice who were fed SGG developed twice the volume of swellings as those given a different microbe.

New research: They discovered human colon cancer apartments in a dish multiplied faster with the bacteria
Additionally, the researchers viewed that human colon cancer cells in a dish multiplied faster with SGG bacteria.
Yi Xu, a on author, said: “Somehow it can stimulate pathways that are important in stall proliferation.”
What’s more, when they tested tumour tastes from people with colon cancer, the researchers discovered that 74 per cent had SGG bacteria in them, while 26 per cent had bloody high levels.
However, it’s still unclear if SGG is behind the initial cancer-causing variations, or if it simply accelerates the growth of existing small tumours.
Bacteria: It’s for the most part found in cows
Future research will involve giving bacteria to in good mice that aren’t pre-disposed to bowel cancer.
If they are masterful to confirm the bacteria’s role in the cancer, it may one day be possible to treat it using antibiotics or arrested with a vaccine.
It’s estimated two to eight per cent of healthy people hold SGG in their colon tissue.
But it isn’t certain how people catch it to start with.
