How It Spreads Gall bladder cancer tends to spread to nearby organs and tissues such as the liver or intestines. It also spreads through the lymph system to lymph nodes in the region of the liver (porta hepatis). Ultimately, other lymph nodes and organs can become involved.
What Causes It No one factor has been clearly shown to cause gall bladder cancer. Although it occurs most often in people with gallstone disease, it is extremely rare even in such patients. It is not known if bouts of gallstones predispose people to developing this cancer.
