Hepatobiliary carcinoma refers to cancers that affect the liver and bile ducts, primarily including hepatocellular carcinoma and cholangiocarcinoma. These cancers can develop due to factors like chronic hepatitis B or C infections, excessive alcohol consumption, and certain liver diseases. Symptoms may include jaundice, abdominal pain, and unexplained weight loss. Diagnosis often involves imaging tests like CT scans or MRIs, along with blood tests to check liver function. Treatment options vary based on the cancer's stage and may include surgery, chemotherapy, or targeted therapies. Early detection is crucial for improving outcomes in patients with hepatobiliary carcinoma.
