Gallbladder polypoid lesions are not necessarily precancerous. Gallbladder polyposis is a morphological name that refers to lesions protruding or bulging into the gallbladder cavity, including tumor polyps (e.g., adenomatous polyps) and non-tumor polyps (e.g., cholesterol polyps, inflammatory polyps), most of which are benign, and a few of which may be cancerous. Among them, gallbladder adenoma is a precancerous lesion of gallbladder cancer with a malignant rate of about 1.5%, and should be treated immediately once diagnosed. Since it is difficult to clarify the nature of gallbladder polyps before surgery, they are generally called gallbladder polypoid lesions. Risk factors for malignant transformation of gallbladder polyps include: a diameter of more than 1 cm; a solitary lesion with a wide base; a polyp that is gradually increasing in size; and a combination of gallbladder stones and thickening of the gallbladder wall. Patients with risk factors for malignancy should be treated early. Patients with gallbladder polyp-like lesions should go to the hospital for further examination to clarify the nature of gallbladder polyps and develop appropriate treatment plans with the help of doctors.
