The gallbladder is a small, pear-shaped sac located beneath the liver. The pouch is responsible for storing bile; the fluid that helps in digestion of fat and is released only when needed.
Most gallbladder and bile duct cancers are adenocarcinomas or cancers of cells that line the glands and ducts.
Even though gallbladder cancers are rare, people with gallstones have a slightly higher risk of developing it.
Gallbladder cancer is more common in women than in men. It responds well if diagnosed early. However, mostly it is diagnosed at a later stage, therefore, patients diagnosed with this cancer type tend to live only a few months.
