Variety of Bacteria Linked to Colorectal Cancer

iStockphoto/Thinkstock(NEW YORK) -- People with a lower variety of bacteria in their intestines may be linked to increased risk of colorectal cancer.

A study conducted by Dr. Jiyoung Ahn at the New York University School of Medicine, involved analysis of 141 individuals, 47 who suffered from colorectal cancer and 94 who did not. Researchers studied the diversity of bacteria in their gut and found that decreased diversity showed some link to the prevalence of cancer, according to HealthDay News.

The study was published in the Journal of the National Cancer Institute.

Many of the colorectal cancer patients in the study had lower levels of the bacteria that ferment fiber, preventing inflammation and possibly the start of cancer in the colon. They also had higher levels of bacteria linked to mouth and gastrointestinal inflammation.

Further studies are needed to determine whether the variety of gut bacteria are necessarily a cause of increased colorectal cancer.
