Gallbladder cancer is a disease in which cancer cells grow in the gallbladder. This is a relatively rare form of cancer. The gallbladder is a small pear-shaped organ. It sits beneath the liver and stores bile until it is needed by the digestive system. Bile is a greenish-yellow digestive fluid produced by the liver that helps in digesting fat.
Cancer occurs when cells in the body (in this case gallbladder cells) divide without control or order. Normally, cells divide in a regulated manner. If cells keep dividing uncontrollably when new cells are not needed, a mass of tissue forms, called a growth or tumor. The term cancer refers to malignant tumors, which can invade nearby tissue and spread to other parts of the body. A benign tumor does not invade nor spread.
