<s>[INST] My husband is experiencing uper abdominal pressure, that radiates to the left around to his back. He had an abdominal ultrasound that found gallbladder polyps, with the sizes not noted in the report, per the physician. I am finding that it is uncommon for the polyps to be the source of the pain, especially radiating to the left. The first few days he started experiencing the pressure, he also had an episode of left arm numbness/tingling. He was checked out in the ER and had a full cardiac work-up and was eventually admitted and released, with a virus. He is now scheduled to have his GB removed, in a few days.Interestingly enough, he has a history of melanoma and an acoustic neuroma. My question is 1. should we be concerned that the polyps are cancerous?2. should we be concerned we are not only dealing with a bad gallbladder?Thank you [/INST] Hi, Polyps are very rarely cancerous, but it is recommended to do cholecystectomy if polyps are found to prevent cancer development in the future. If cancer is found now after removal, it is in most cases curative surgery, and then you can be happy that it was detected in such early phase. It can't be missed that this polyps is inside the gallbladder, don't need to worry about this. I hope I have answered you query. If you have any further questions you can contact us in every time. Kindly regards, </s>
