Gallbladder adenocarcinoma causes

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.


 * Ethnicity: Epidemiology data demonstrates that Mexican Americans and Native Americans, particularly in the southwestern United States, are more likely to develop gallbladder cancer than the general population.


 * Age: Clinical data shows most people with gallbladder cancer are older than 70.


 * Gender: Epidemiology data shows women are about twice as likely to develop gallbladder cancer as men.


 * Smoking: Smoking may increase the risk of gallbladder cancer.
