Gallbladder cancer is cancer that begins in the gallbladder. Your gallbladder is a small, pear-shaped organ on the right side of your abdomen, just beneath your liver. The gallbladder stores bile, a digestive fluid produced by your liver.
Gallbladder cancer is common. When gallbladder cancer is discovered at its earliest stages, the chance for a cure is very good. But most gallbladder cancers are discovered at a late stage, when the prognosis is often very poor.
Gallbladder cancer is difficult to diagnose because it often causes no specific signs or symptoms. Also, the relatively hidden nature of the gallbladder makes it easier for gallbladder cancer to grow without being detected.
Gallbladder cancer signs and symptoms may include:
It’s not clear what causes gallbladder cancer. Doctors know that gallbladder cancer forms when healthy gallbladder cells develop changes (mutations) in their DNA. These mutations cause cells to grow out of control and to continue living when other cells would normally die. The accumulating cells form a tumor that can grow beyond the gallbladder and spread to other areas of the body.
Most gallbladder cancer begins in the glandular cells that line the inner surface of the gallbladder. Gallbladder cancer that begins in this type of cell is called adenocarcinoma. This term refers to the way the cancer cells appear when examined under a microscope.
Factors that can increase the risk of gallbladder cancer include:
Tests and procedures used to diagnose gallbladder cancer include:
The stages of gallbladder cancer are:
What gallbladder cancer treatment options are available to you depend on the stage of your cancer, your overall health and your preferences. The initial goal of treatment is to remove the gallbladder cancer, but when that isn’t possible, other therapies may help control the spread of the disease and keep you as comfortable as possible.
Surgery may be an option if you have an early-stage gallbladder cancer. Options include:
It’s not clear whether additional treatments after successful surgery can increase the chances that your gallbladder cancer won’t return. Some studies have found this to be the case, so in some instances, your doctor may recommend chemotherapy, radiation therapy or a combination of both after surgery. Discuss the potential benefits and risks of additional treatment to decide what’s right for you.
Surgery can’t cure gallbladder cancer that has spread to other areas of the body. Instead, doctors use treatments that may relieve signs and symptoms of cancer and make you as comfortable as possible. Options may include:
Advanced gallbladder cancer can cause blockages in the bile ducts, causing further complications. Procedures to relieve the blockage may help. For instance, surgeons can place a hollow metal tube (stent) in a duct to hold it open or surgically reroute bile ducts around the blockage (biliary bypass).
