Gall Bladder Cancer Health Center

Gallbladder cancer is a rare disease in which malignant (cancer) cells are found in the tissues of the gallbladder. The gallbladder is a pear-shaped organ that lies just under the liver in the upper abdomen. The gallbladder stores bile, a fluid made by the liver to digest fat. When food is being broken down in the stomach and intestines, bile is released from the gallbladder through a tube called the common bile duct, which connects the gallbladder and liver to the first part of the small intestine.

The wall of the gallbladder has 3 main layers of tissue:

  • mucosal (inner) layer
  • muscularis (middle, muscle) layer
  • serosal (outer) layer

Between these layers is supporting connective tissue. Primary gallbladder cancer starts in the inner layer and spreads through the outer layers as it grows.
