What is Gallbladder Cancer?
Gallbladder cancer is an uncommon, aggressive cancer that develops in the gallbladder, a small pear-shaped organ located beneath the liver in the upper right abdomen. The gallbladder stores bile, a fluid produced by the liver to help digest fats. Because of the relatively hidden nature of the organ, gallbladder cancer can be difficult to diagnose. There are often no specific symptoms in its early stages when the chances for a cure are higher. Gallbladder cancer may not be discovered until it’s in an advanced stage.
Risk Factors
Gallstones: The most common risk factor for gallbladder cancer is the presence of gallstones. While most people with gallstones never develop gallbladder cancer, a significant majority of people with gallbladder cancer have had gallstones.
- Gender and Age: Gallbladder cancer is more common in women than in men, and the risk increases with age.
- Obesity: Excess body weight has been linked to an increased risk of gallbladder cancer, possibly due to its association with gallstones.
- Ethnicity: The incidence of gallbladder cancer varies significantly across different ethnic groups and geographical regions. It is more common in people with South American, Central and Eastern European, and Northern Indian heritage.
- Family History and Genetic Factors: A family history of gallbladder cancer can increase the risk, though specific genetic mutations linked directly to gallbladder cancer are still under study.
- Chronic Gallbladder Inflammation: Chronic inflammation, often due to gallstones, can lead to changes in the gallbladder lining, which might increase cancer risk.
- Porcelain Gallbladder: This condition, where the gallbladder wall becomes covered with calcium deposits, is associated with a higher risk of gallbladder cancer.
- Biliary Tract Diseases: Other diseases affecting the bile ducts, like primary sclerosing cholangitis, can increase the risk.
- Infections: Certain bacterial and parasitic infections, particularly those affecting the bile ducts, have been linked to an increased risk of gallbladder cancer.
