So if gallbladder polyp went down frim 6.5 mm to 4mm is that lean away from cancer?

Yes: Would continue to follow up with your doctor for monitoring. Occasionally gallstones can be mistaken for polyps. Watch for abdominal pain, nausea, vomiting, fevers, and yellowing of the skin which should be reported to your physician immediately.

LOW RISK: The vast majority of gb polyps are indeed benign. Any polyp less than 10mm is considered inconsequential. Ultrasound annual monitoring of gb polyps is reasonable, at least to establish if they are stable and not enlarging. It would be reasonable to assume that a small and stable, or shrinking, polyp would be benign.
