Overview
Causes
There are some factors that may increase the chance of acquiring gallbladder cancer. These risk factors include:
- Gallstones: This is the most common risk factor for gallbladder cancer. It is estimated that about 75% and 90% of people with gallbladder cancer have a history of gallstones. Gallstones are the most common digestive disease in the United States, but only a small proportion of people develop gallbladder cancer.
- Gallbladder polyps: Gallbladder polyp is caused by small gallstones or cholecystitis. Because gallbladder polyps larger than 10 millimeters are likely to develop into cancer, surgeons often recommend removing the gallbladder.
- Family history. People with family history of gallbladder cancer have a higher probability of developing gallbladder cancer.
- Smoking: Smoking may increase the risk of gallbladder cancer.
