Patients with early-stage gallbladder cancer generally do not display specific symptoms or obvious precursors. Some patients may experience digestive symptoms such as abdominal bloating, indigestion, nausea, and vomiting, but these are often overlooked. Thus, by the time gallbladder cancer is diagnosed, it is usually at an advanced stage, where the pain becomes significant and is one of the main reasons patients seek medical attention.

Additionally, some patients may experience weight loss and even develop cachexia. Gallbladder cancer is a highly malignant tumor with rapid progression and a tendency to metastasize to other parts of the body, resulting in a very poor prognosis. Therefore, once diagnosed with gallbladder cancer, it is crucial to complete relevant examinations, rule out any contraindications for surgery, and proceed with surgical removal as soon as possible.
