Cervical myomas are smooth, round tumors composed mostly of muscle tissue. These myomas are present in the cervix and are much rarer than uterine myomas, also known as uterine fibroids. However, the two types of tumors can appear together as well.
Myomas are benign tumors, meaning they are not cancerous. However, they can cause serious problems in some cases, especially if they are large. They may block part of the urinary tract or prolapse through the cervix and into the vaginal canal. Prolapsed myomas may develop ulcers, which could cause abnormal bleeding or infection.
What Causes Cervical Myomas?
Myomas are thought to be caused by an excess of estrogen, a hormone involved in cellular growth. Myomas may also develop with an imbalance between estrogen and progesterone.
Symptoms of Cervical Myomas
Mild cervical myomas may not cause any problems while moderate to severe myomas may cause one or more of these symptoms:
- Abnormal vaginal bleeding, especially heavy bleeding or bleeding between periods
- Anemia, as a result of heavy bleeding, accompanied by fatigue
- Painful intercourse
- Vaginal discharge
- Pelvic pain
- A bulge in the abdomen or feeling of heaviness
- Difficulty urinating or incomplete urination, including a urine stream that hesitates to start or dribbles at the end
- Urinary tract infections
Diagnosing Cervical Myomas
If you’re experiencing these symptoms, please make an appointment for an exam. In most cases, cervical myomas can be diagnosed with a pelvic exam. Your doctor can also use a transvaginal ultrasound to help diagnose the problem.
At your appointment, your doctor may also want to run additional diagnostic tests to evaluate the condition.
Cervical Myomas Treatment
Small myomas that do not cause symptoms may not need to be treated. Your OB-GYN may still want to keep an eye on your condition over time.
Larger myomas that are causing pain, bleeding or urinary problems can be surgically removed via myomectomy. Depending on the size and location of your myomas, your doctor may perform one of three procedures.
Laparoscopy
A procedure in which the surgeon conducts the operation through one or more tiny incisions near your belly button. A thin, flexible, lighted instrument, called a laparoscope, helps your doctor to see the surgical site.
Laparotomy
An open surgical procedure in which the surgeon removes the myomas through a larger abdominal incision.
Hysterectomy
Complete surgical removal of the uterus and sometimes the ovaries. If the myomas are very large, this may be the surgeon’s only option. After a hysterectomy, it is no longer possible to become pregnant. You should share your plans for having children with your doctor when discussing your treatment options.
