Patients with gallbladder cancer may develop obstructive jaundice as the tumor size increases, which can manifest as yellowing of the skin and mucous membranes, dark urine, and pale stools. Patients may also experience itching and discomfort. For these patients, the treatment effectiveness is generally poor, and gallbladder cancer is a type of malignancy that tends to metastasize and has a very poor prognosis. Once symptoms are prominent, treatment becomes relatively difficult and less effective. It is advisable for gallbladder cancer patients to undergo surgical resection as early as possible to improve their prognosis. However, the onset of gallbladder cancer is often insidious and frequently overlooked.
