Whether a polyp is serious or not needs to be judged by the size and location of the polyp, so the severity of polyps with different locations and sizes varies greatly. For example, if a polyp that is no larger than one centimeter grows on the cervical area of a woman and does not show adverse symptoms such as bleeding after sex, it is generally not serious and can even be left untreated and only needs to be followed up and reviewed. However, if the polyp is in the uterine cavity and is already larger than one centimeter, it can lead to increased and prolonged menstruation, as well as symptoms of irregular menstruation, which is more serious and may even affect pregnancy. Polyps that grow in the stomach are usually not serious, the most common of which are fundic gland polyps and have a very low chance of becoming diseased. If the polyp does not exceed one centimeter and there is no polyp growth after the review, it can be left alone, but if it is more than one centimeter, it needs to be removed. The key to determine whether the polyp is cancerous or not depends on the biopsy pathology results of the polyp.
