Cholangiocarcinoma20
- Cholangiocarcinoma, also known as bile duct cancer, is a type of cancer that forms in the bile ducts. (wikipedia.org)
- Risk factors for cholangiocarcinoma include primary sclerosing cholangitis (an inflammatory disease of the bile ducts), ulcerative colitis, cirrhosis, hepatitis C, hepatitis B, infection with certain liver flukes, and some congenital liver malformations. (wikipedia.org)
- The most common physical indications of cholangiocarcinoma are abnormal liver function tests, jaundice (yellowing of the eyes and skin occurring when bile ducts are blocked by tumor), abdominal pain (30-50%), generalized itching (66%), weight loss (30-50%), fever (up to 20%), and changes in the color of stool or urine. (wikipedia.org)
