Bile duct cancer

Bile duct cancer

Bile duct cancer, also known as cholangiocarcinoma, is a rare cancer that forms in the bile ducts, which are responsible for carrying bile from the liver to the small intestine. This cancer can develop in different parts of the bile ducts, either inside or outside the liver, and is typically aggressive with a poor prognosis if not detected early.

The exact cause of bile duct cancer is often unclear, but certain risk factors increase the likelihood of developing it. These include chronic inflammation of the bile ducts, bile duct cysts, liver fluke infections (common in certain regions), primary sclerosing cholangitis, and conditions like cirrhosis. Smoking and age also contribute to the risk.

Early symptoms of bile duct cancer are often subtle or nonexistent, making it difficult to detect in its initial stages. Common symptoms that may eventually appear include jaundice, abdominal pain, itchy skin, dark urine, and pale stools. Unexplained weight loss and fatigue can also be signs of the disease.

Diagnosis of bile duct cancer is typically made through imaging tests such as MRI, CT scans, and ERCP (Endoscopic Retrograde Cholangiopancreatography). Blood tests and biopsies are also used to confirm the diagnosis and determine the extent of the cancer’s spread.

Treatment options for bile duct cancer depend on its location and stage. Surgical removal of the tumor, when feasible, offers the best chance for a cure. For inoperable cases, treatments like chemotherapy, radiation therapy, or targeted therapies may be employed to control the disease and improve the patient's quality of life. Early detection greatly improves the chances of successful treatment.
