Intestinal microecology and cancer A number of studies have focused on the impact of probiotics on intestinal microecology and cancer. Lactobacillus acidophilus, L. casei Shirota strain, and LGG have been shown to have inhibitory effects on chemically induced tumors in animals. Some specific strains of probiotic bacteria are able to bind carcinogens and to downregulate some microbial carcinogenic enzymatic activities. This phenomenon may then reduce carcinogen production and exert a beneficial effect in the colon, the urinary tract, and the bladder.
