Cervical cysts: Can they be cancerous?
Can cervical cysts be cancerous?
Answer
from Mary Gallenberg, M.D.
Cervical cysts — mucus-filled lumps that form on the cervix — are rarely cancerous. Cervical cysts, also called nabothian cysts, form when normal tissue on the outer part of the cervix (squamous epithelium) grows over the glandular mucus-producing tissue of the inner part of the cervix (endocervical canal). Cervical mucus is trapped, forming cysts.
Cervical cysts usually are discovered incidentally during a pelvic exam. They typically cause no symptoms and don't require treatment unless they grow large enough to cause pain. In such cases, treatment may include removal of the cyst.
In the rare case that a cervical cyst has an unusual appearance or is accompanied by the signs and symptoms suggestive of cervical cancer, such as abnormal vaginal bleeding or discharge, pelvic pain, or pain during intercourse, your doctor may perform a colposcopic exam. Colposcopy is a procedure in which your doctor inserts a speculum just as when taking a Pap test sample, but uses a special magnifying instrument to visualize the cervix. If the cyst appears abnormal during a colposcopic exam, your doctor may perform a biopsy to rule out cancer.
