Gallbladder polyps are mostly benign lesions; some specific types of gallbladder polyps may turn into cancer, but the exact time of cancer cannot be generalized. Gallbladder polyps refer to mucosal bulging lesions in the gallbladder, which are mostly caused by inflammation, genetics or other factors repeatedly stimulating. If the gallbladder polyp is <1cm, the ultrasound can be reviewed regularly, if there is no significant change and the patient has no obvious symptoms, there is no need to deal with it. If the polyp is >1cm and solitary, the probability of malignant change is 10%-20%. If the polyp is >2cm with wide tip and the patient is >60 years old, the chance of malignant change is about 30%-50%, so early surgery is recommended to prevent the possibility of cancer. In addition, there is a type of gallbladder polyp called adenomatous polyp, which is also potentially malignant and requires dynamic follow-up and, if necessary, early surgical removal. Patients with gallbladder polyps need to pay attention to regular medical checkups, and if gallbladder polyps are found, they need to be dynamically observed at intervals, and if necessary, they can be treated accordingly to avoid adverse consequences.
