At Significantly Higher Risk 
• About 85 percent of people with gall bladder cancer have a history of gallstones (cholelithiasis). Sometimes, 
  although not often, the gall bladder becomes hardened (calcified) from repeated inflammation as gallstones are 
  passed. People with this "porcelain gall bladder" have a higher risk of developing this cancer than do others. 
  The typical patient with gall bladder cancer is an elderly woman with a history of gall bladder problems.

At Slightly Higher Risk 
• Gallstone disease without a "porcelain gall bladder."
