What is gall bladder cancer?

Gall bladder cancer occurs when cells in the mucosal layer of the gall bladder grow abnormally, forming a growth or tumour that is malignant (cancerous).

The gall bladder is a pear-shaped organ located under the liver, and its function is to store bile, a liquid produced by the liver to help digest fat. Bile travels through a tube called the common bile duct, which connects your gall bladder to your small intestine.

Gall bladder cancer is difficult to diagnose and often detected by chance or when it has already progressed to a late stage. It can spread to other parts of the body to nearby tissues, through the lymphatic system or the blood's circulatory system.

Gall bladder cancer is relatively rare in Singapore, occurring in 1.7 out of every 100,000 people.
