What is gallbladder cancer?
Gallbladder cancer starts in cells of the gall bladder. The gallbladder is a small, pear-shaped organ on the right side of the body, under the liver. Your liver makes a fluid called bile that helps your body digest fats. The gallbladder stores this bile and then releases it into the small intestine to help digestion. The bile ducts are tubes that carry bile from the liver to the gallbladder and from the gallbladder to the small intestine. Together, the liver, bile ducts and gallbladder are called the biliary system or biliary tract.
The most common type of gallbladder cancer is called adenocarcinoma. An adenocarcinoma starts in gland cells that line the gallbladder.
