In general, most broad-based polyps are benign, but the possibility of malignancy cannot be ruled out, and there may be a risk of cancer. A broad-based polyp is a type of polyp that has a wide base and can be single or multiple. The vast majority of broad-based polyps are benign, but a very small percentage of broad-based polyps are malignant, and a common way to identify the nature of a broad-based polyp is to perform a pathologic examination. Broad-based polyps are generally more likely to be malignant than pedunculated polyps. Therefore, when a broad-based polyp is detected on examination, biopsy or direct excision followed by pathologic examination is generally recommended. Broad-based polyps can be found in many parts of the body, such as the intestines, uterus, and cervix. If the polyp is relatively small and has no obvious symptoms, it can be observed and followed up with regular physical examinations to further define the type of lesion. If the polyp is large and accompanied by pain, it needs to be surgically removed and pathologically examined.
