Bile acids were first considered carcinogenic in 1939. Since then, accumulated data have associated colon cell changes with high levels of bile acids as an important risk factor for developing colorectal cancer, which is more common among people who consume large amounts of dietary fat. Secondary bile acids formed under the influence of the intestinal microbiota can cause the formation of reactive forms of oxygen and nitrogen, disruption of the cell membrane, mitochondria, DNA damage, reduction

of apoptosis, increased cell mutation, turning them into cancer cells. High-fat diet, intestinal microflora, bile acids are a risk factors for colorectal cancer.
