Hepatobiliary cancer refers to malignancies that originate in the liver, bile ducts, or gallbladder. Common types include hepatocellular carcinoma, cholangiocarcinoma, and gallbladder cancer. Risk factors vary but may include chronic viral hepatitis, alcohol abuse, obesity, and certain genetic conditions. Symptoms can include abdominal pain, jaundice, weight loss, and changes in appetite. Diagnosis involves imaging tests, blood tests, and sometimes biopsy. Treatment options depend on the type, stage, and location of the cancer, and may include surgery, chemotherapy, radiation therapy, or targeted therapy. The prognosis varies depending on the extent of the disease and the patient's overall health. Early detection and prompt treatment can improve outcomes.
