Gallbladder polyps are “tumors” growing in the gallbladder, the danger is: 1, if it is a true polyp (equivalent to a tumor growing out of the gallbladder), polyps larger than 1.0cm have cancerous changes in individual patients. 2, there is also the possibility of chronic cholecystitis, chronic cholecystitis is generally manifested as the right upper abdomen or the subsurface of the sword hidden pain discomfort (can also be the right back or right shoulder pain), in addition to pain can also be the right upper abdomen or epigastric fullness, if the site of symptoms is not the right side, but the subsurface of the sword, many patients are mistaken for “stomach disease If the symptom is not on the right side, but under the saber, many patients mistake it for “stomach disease” and often treat it as stomach disease. Therefore, surgical removal is recommended in symptomatic cases, and it is up to the patient to decide whether to remove the polyp without symptoms. Gallbladder polyps are divided into two types: true polyps and pseudopolyps. It is difficult to identify whether they are true polyps (tumors) or pseudopolyps (cholesterol crystals, which can also be called stones) before surgery. If it is a pseudopolyp, the polyp itself is not cancerous, however, if it is accompanied by chronic cholecystitis, the gallbladder may also be cancerous.
