Symptoms are similar to gallstones and can include abdominal pain (especially after eating), jaundice, and vomiting.<unk>  can also be asymptomatic and discovered on imaging obtained for a different reason. Association with cancer The assertion that<unk>  increases the incidence of gallbladder cancer is widely taught in medical schools but is based on studies from 1931 and 1962. A prominent study aid for surgical residents even states that the risk of cancer in a<unk>  is 15%. The precise nature of the association between gallbladder cancer and<unk>  is uncertain. Two articles published in 2001 examined the association between cancer of the gallbladder and calcified gallbladder. The first study reviewed 10,741 cholecystectomies and found that the 88 patients with gallbladder cancer did not have calcified gallbladders while the 15 patients with<unk> s did not have gallbladder cancer. The second study reviewed 25,900 gallbladder specimens and found 150 patients with cancer and 44 patients with calcified gallbladders of two types (intramural calcification and selective mucosal calcification). The selective mucosal calcification group showed a 7% incidence of cancer with a significant odds ratio of 13.89. An article published in 2013 reviewed 111 studies and found 340 patients with gallbladder wall calcification showed a 21% overall rate of gallbladder malignancy; however, when studies with obvious selection bias were excluded the rate of gallbladder malignancy fell to 6%. Comparatively, a matched cohort without gallbladder calcification showed a 1% rate of gallbladder malignancy.
