The actual cervical cavity is mainly formed when the squamous epithelium on the surface of the cervix is replaced by the columnar epithelium below, which is a physiological cavity and not a real cavity. Mild cervical cavity does not appear to have contact bleeding or increased leucorrhea discharge, which can also be temporarily observed first. The actual cervical cavity is a very good place to get a good deal of time and money. The effect of oral anti-inflammatory drugs is not good.
