Bile Duct Cancer (Cholangiocarcinoma)

Cholangiocarcinoma is a rare cancer that occurs in the bile ducts, which are tubes that carry bile from the liver to the small intestine. It can occur in different parts of the bile duct system and can be classified as intrahepatic or extrahepatic, depending on the location. Symptoms of cholangiocarcinoma include jaundice, abdominal pain, weight loss, and fatigue. The exact causes of cholangiocarcinoma are unknown, but risk factors include chronic inflammation of the bile ducts, infection with certain parasites, and exposure to certain chemicals. Treatment may involve surgery, chemotherapy, radiation therapy, or a combination of these. The prognosis for cholangiocarcinoma can vary depending on the stage of the cancer and other factors, but early diagnosis and treatment can improve outcomes.
