Gallbladder wall thickening can be a sign of a cancerous or noncancerous gallbladder condition. Some conditions other than gallbladder cancer, like hepatitis, can also cause gallbladder thickening.

Gallbladder cancer is a rare but serious type of cancer where abnormal cells in the gallbladder grow out of control. The gallbladder, a small organ under the liver, stores bile to help digest food.

Due to its aggressive nature, gallbladder cancer is often detected and diagnosed in later stages. Staging is determined by the size of the tumor and where in your body the cancer has spread.
