Gallbladder cancer is fairly rare, accounting for about 1% of incidence of all cancers, and is more common in women than in men.
Approximately 90–95% of gallbladder cancers are adenocarcinomas, while only a small proportion are squamous cell carcinomas. The gallbladder is a small sac-like organ that forms part of the biliary tract. Bile, produced in the liver, flows into the gallbladder where it is stored and concentrated until released into the small intestine.
AICR’S latest report on gallbladder cancer found that maintaining a healthy weight can lower your risk. Having gallstones increases the risk of this cancer.
Lifestyle and gallbladder cancer risk.
Excess body fatness puts you at greater risk for gallbladder cancer.
- Obesity is a known cause of gallstone formation and having gallstones increases the risk of gallbladder cancer.
- Body fatness increases the levels of hormones circulating in the body – such as insulin and insulin-like growth factors – creating an environment that may encourage the development or progression of cancer in a variety of organs.
- Body fat also stimulates a general in inflammatory response, which may contribute to the development of several cancers.
The science of survival.
AICR’s health guides and recommendations are developed from research that focuses on how nutrition and lifestyle affect the prevention, treatment, and survival of cancer. Paramount to our updates is the Continuous Update Project which helps you stay on top of new findings, and understand the data that sits at the center of our work.
