A wide-base polyp is simply a polyp that is wider at the base, but it is not necessarily malignant.
Clinically, narrow polyps, especially those with tips, have a narrower contact surface with the surrounding tissues, so that removal is easier compared to wide-base polyps. Wide-base polyps, on the other hand, show that the base of the polyp is relatively wide, forming a complete whole with the surrounding intestinal tissues, which makes endoscopic resection relatively difficult.
Among the common intestinal polyps, those with a wide base are mostly adenomatous polyps, which have a higher rate of malignancy, but not all adenomatous polyps are malignant.
To determine the degree of benign and malignant polyps, the final diagnosis is still based on pathological examination to diagnose. If the polyp is found to be wide at the base, rich in blood flow, or growing rapidly in a short period of time, it is considered to have the possibility of malignant transformation. In this case, it is necessary to take a biopsy tissue and send it to the Department of Pathology for examination to determine whether there is malignant transformation.
Whether or not a wide base polyp is malignant, it is recommended to consult a regular hospital, and if necessary, a pathology examination is needed to make a clear diagnosis.
