Gallbladder Cancer: Gallstones are present in about 80% of people with gallbladder cancer. There is a strong association between gallbladder cancer and cholelithiasis, chronic cholecystitis, and inflammation. Symptoms of gallbladder cancer usually do not appear until the disease has reached an advanced stage and may include weight loss, anemia, recurrent vomiting, and a lump in the abdomen.

Research shows that survival rates for gallbladder cancer are on the rise, although the death rate remains high because many people are diagnosed when the cancer is already at a late stage. When the cancer is caught at an early stage and has not spread beyond the mucosa (inner lining), removing the gallbladder (resection) can cure many people with the disease. If the cancer has spread beyond the gallbladder, other treatments may be required.

This cancer is very rare, even among people with gallstones. Certain conditions in the gallbladder, however, contribute to a higher-than-average risk for this cancer.

Gallbladder Polyps. Polyps (growths) are sometimes detected during diagnostic tests for gallbladder disease. Small gallbladder polyps (up to 10 mm) pose little or no risk, but large ones (greater than 15 mm) pose some risk for cancer, so the gallbladder should be removed. Patients with polyps 10 - 15 mm have a lower risk, but they should still discuss gallbladder removal with their doctor.

Primary Sclerosing Cholangitis. Primary sclerosing cholangitis is a rare disease that causes inflammation and scarring in the bile duct. It is associated with a lifetime risk of 7 - 12% for gallbladder cancer. The cause is unknown, although it tends to strike younger men with ulcerative colitis. Polyps are often detected in this condition and have a very high likelihood of being cancerous.

Anomalous Junction of the Pancreatic and Biliary Ducts. With this rare condition, which is present at birth (congenital), the junction of the common bile duct and main pancreatic duct is located outside the wall of the small intestine and forms a long channel between the two ducts. This problem poses a very high risk of cancer in the biliary tract.
