Causes of Nabothian Cysts
The cervix is located at the bottom of the uterus. It connects the uterus to the top of the vagina. Irregular cells on the cervix are causes of nabothian cysts. The lining of the cervix contains glands that secrete mucus.
Sometimes, squamous epithelium cells (a type of skin cells) plug up the glands. This causes a smooth, mucus-filled bump to develop. In a pelvic exam, the bumps look like small, white rounded lumps.
As a benign condition, nabothian cysts do not require treatment.
