Gallbladder Cancer

There is no screening test for gallbladder cancer like there are for some other cancers, which makes it harder to find the disease at an early stage.
Although progress is being made in detecting and understanding many types of cancer and what might cause them, gallbladder cancer remains something of a mystery. 
In the United States, gallbladder cancer is rare. While most people with gallbladder cancer have gallstones, only a small fraction of people with gallstones develop gallbladder cancer.
