Which is a recognized risk factor for cholangiocarcinoma?

Cholangiocarcinoma risk rises with chronic inflammation of the bile ducts. Primary sclerosing cholangitis causes long-standing inflammation and fibrosis of the biliary tree, leading to ongoing injury and regeneration of biliary epithelium. This environment promotes genetic mutations and malignant transformation of cholangiocytes, making it a well-recognized risk factor. Hepatic adenoma is a benign tumor; while malignant transformation can occur, it more commonly risks hepatocellular carcinoma rather than cholangiocarcinoma. Alcoholic liver disease and nonalcoholic fatty liver disease mainly raise risk for cirrhosis and hepatocellular carcinoma, not cholangiocarcinoma, so they’re not classic risk factors for this cancer.
