A little organ beneath the liver called the gallbladder is where gallstones, which resemble microscopic pebble-like deposits, originate. They can be as little as grains or as large as stones, and are often formed of hardened cholesterol or bilirubin. When the components that make up bile, a digestive fluid kept in the gallbladder, are out of balance, gallstones can form.

Gallstones are normally treated by controlling symptoms, with choices ranging from dietary adjustments to surgical gallbladder removal (cholecystectomy). Patients can maintain a normal quality of life without the gallbladder because to this operation, which is frequently minimally invasive. Depending on the stage of the cancer, treatment options for gallbladder cancer may combine surgery, chemotherapy, radiation therapy, or all. The likelihood of effective treatment is significantly increased by early identification.
