I had a scan last month and found multiple gall bladder polyps and largest is 4.8 mm echogenic foci attached to wall of gb 2nd scan recently at different center resulted: Multiple hyperechoic foci, largest is app 6mm adherent to gb wall. On same day i had another scan at the same center which i had last month but they report 4.8 mm polyp but they had my previous month report Does the polyp size increase in a month or 3rd scan i had is inaccurate in size I have no symptoms and No pain What is the risk of polyp being malignant ?
