Cancers of the gallbladder and bile duct are known collectively as bilary tract cancers. Bile duct cancer is also known as cholangiocarcinoma.
According to the Mayo Clinic, bilary tract cancers are relatively rare in the United States.
When they do occur, these cancers of the biliary tract affect a disproportionate number of American Indians, Alaska natives and Hispanics, who may have rates five times that of whites. This may be the result of a genetic propensity to gallstones, one of the leading causes of gallbladder cancer.
[Editor's Note: True as this may be, cultural factors should be taken into consideration. Please see our discussion on Race as a Risk Factor.]
