Taking a probiotic, similar to what’s found in yogurt, may help cancer patients avoid intestinal injury, a common problem in those receiving radiation therapy for abdominal cancers. The research is published online in the journal Gut.

Radiation therapy often is used to treat prostate, cervical, bladder, endometrial, and other abdominal cancers. But the therapy can kill both cancer cells and healthy ones, leading to severe bouts of diarrhea if the lining of the intestine gets damaged

For many patients, this means radiation therapy must be discontinued, or the radiation dose reduced, while the intestine heals

The average human gut contains about 1 kg of bacteria. Why you must WASH YOUR HANDS: E.coli bacteria thrive in nutrient-rich environments like the guts of humans or cows before being discharged. This strain has been found to be particularly sticky, making it likely to cling on to leaves, seeds and other foodstuffs.

But these bugs are also sensitive to the outside world, so a lack of nutrients or changes in temperature, salt concentration or PH levels could be enough to finish them off.
