What Causes Gallbladder Cancer?
Gallbladder cancer develops in the tissues of the gallbladder, the organ in the body that collects bile from the liver used to digest fat. Gallstones occur when bile inside the gallbladder hardens. While important to digesting fat, the gallbladder can be removed without causing problems. The causes of gallbladder cancer are unclear. According to the National Cancer Institute, gallbladder cancer is uncommon with only 9,760 cases reported in the United States in 2009.
