July is National Fibroid Awareness Month. 

 

Uterine fibroids are noncancerous growths of the uterus that often appear during childbearing years. Also called leiomyomas (lie-o-my-O-muhs) or myomas, uterine fibroids aren't associated with an increased risk of uterine cancer and almost never develop into cancer.  Fibroids range in size from seedlings, undetectable by the human eye, to bulky masses that can distort and enlarge the uterus. You can have a single fibroid or multiple. In extreme cases, multiple fibroids can expand the uterus so much that it reaches the rib cage and can add weight.
 

Many women have uterine fibroids sometime during their lives. But, you might not know you have uterine fibroids because they often cause no symptoms. Your doctor may discover fibroids incidentally during a pelvic exam or prenatal ultrasound.

​

Symptoms

Many women who have fibroids don't have any symptoms. In those that do, symptoms can be influenced by the location, size and number of fibroids.
 

In women who have symptoms, the most common signs and symptoms of uterine fibroids include:

• Heavy menstrual bleeding

• Menstrual periods lasting more than a week

• Pelvic pressure or pain

• Frequent urination

• Difficulty emptying the bladder

• Constipation

• Backache or leg pains

​

Rarely, a fibroid can cause acute pain when it outgrows its blood supply, and begins to die.  Fibroids are generally classified by their location

​

When to see a doctor

See your doctor if you have:

• Pelvic pain that doesn't go away

• Overly heavy, prolonged or painful periods

• Spotting or bleeding between periods

• Difficulty emptying your bladder

• Unexplained low red blood cell count (anemia)
   

Seek prompt medical care if you have severe vaginal bleeding or sharp pelvic pain that comes on suddenly.

Treatment

There's no single best approach to uterine fibroid treatment, however, many treatment options exist. If you have symptoms, talk with your doctor about options for symptom relief.

Watchful waiting

Many women with uterine fibroids experience no signs or symptoms, or only mildly annoying signs and symptoms that they can live with. If that's the case for you, watchful waiting could be the best option.  Fibroids aren't cancerous. They rarely interfere with pregnancy. They usually grow slowly, or not at all, and tend to shrink after menopause, when levels of reproductive hormones drop.

Medication

Medication for uterine fibroids target hormones that regulate your menstrual cycle, treating symptoms such as heavy menstrual bleeding and pelvic pressure. They don't eliminate fibroids, but may shrink them. Medication includes:

• Gonadotropin-releasing hormone (GnRH) agonists. Medications called GnRH agonists treat fibroids by blocking the production of estrogen and progesterone, putting you into a temporary menopause-like state. As a result, menstruation stops, fibroids shrink and anemia often improves.

  GnRH agonists include leuprolide (Lupron Depot, Eligard, others), goserelin (Zoladex) and triptorelin (Trelstar, Triptodur Kit).

  Many women have significant hot flashes while using GnRH agonists. GnRH agonists typically are used for no more than three to six months because symptoms return when the medication is stopped and long-term use can cause loss of bone.

  Your doctor may prescribe a GnRH agonist to shrink the size of your fibroids before a planned surgery or to help transition you to menopause.

• Progestin-releasing intrauterine device (IUD). A progestin-releasing IUD can relieve heavy bleeding caused by fibroids. A progestin-releasing IUD provides symptom relief only and doesn't shrink fibroids or make them disappear. It also prevents pregnancy.

• Tranexamic acid (Lysteda, Cyklokapron). This nonhormonal medication is taken to ease heavy menstrual periods. It's taken only on heavy bleeding days.

• Other medications. Your doctor might recommend other medications. For example, oral contraceptives can help control menstrual bleeding, but they don't reduce fibroid size.

  Nonsteroidal anti-inflammatory drugs (NSAIDs), which are not hormonal medications, may be effective in relieving pain related to fibroids, but they don't reduce bleeding caused by fibroids. Your doctor may also suggest that you take vitamins and iron if you have heavy menstrual bleeding and anemia.
   

Noninvasive procedure

Focused ultrasound surgery

MRI-guided focused ultrasound surgery (FUS) is:

• A noninvasive treatment option for uterine fibroids that preserves your uterus, requires no incision and is done on an outpatient basis.

• Performed while you're inside an MRI scanner equipped with a high-energy ultrasound transducer for treatment. The images give your doctor the precise location of the uterine fibroids. When the location of the fibroid is targeted, the ultrasound transducer focuses sound waves (sonications) into the fibroid to heat and destroy small areas of fibroid tissue.

• Newer technology, so researchers are learning more about the long-term safety and effectiveness. But so far data collected show that FUS for uterine fibroids is safe and effective.

Minimally invasive procedures

Uterine artery embolization

Laparoscopic radiofrequency ablation

Certain procedures can destroy uterine fibroids without actually removing them through surgery. They include:

• Uterine artery embolization. Small particles (embolic agents) are injected into the arteries supplying the uterus, cutting off blood flow to fibroids, causing them to shrink and die.

  This technique can be effective in shrinking fibroids and relieving the symptoms they cause. Complications may occur if the blood supply to your ovaries or other organs is compromised. However, research shows that complications are similar to surgical fibroid treatments and the risk of transfusion is substantially reduced.

• Radiofrequency ablation. In this procedure, radiofrequency energy destroys uterine fibroids and shrinks the blood vessels that feed them. This can be done during a laparoscopic or transcervical procedure. A similar procedure called cryomyolysis freezes the fibroids.

  With laparoscopic radiofrequency ablation (Acessa), also called Lap-RFA, your doctor makes two small incisions in the abdomen to insert a slim viewing instrument (laparoscope) with a camera at the tip. Using the laparoscopic camera and a laparoscopic ultrasound tool, your doctor locates fibroids to be treated.

  After locating a fibroid, your doctor uses a specialized device to deploy several small needles into the fibroid. The needles heat up the fibroid tissue, destroying it. The destroyed fibroid immediately changes consistency, for instance from being hard like a golf ball to being soft like a marshmallow. During the next three to 12 months, the fibroid continues to shrink, improving symptoms.

  Because there's no cutting of uterine tissue, doctors consider Lap-RFA a less invasive alternative to hysterectomy and myomectomy. Most women who have the procedure get back to regular activities after 5 to 7 days of recovery.

  The transcervical — or through the cervix — approach to radiofrequency ablation (Sonata) also uses ultrasound guidance to locate fibroids.

• Laparoscopic or robotic myomectomy. In a myomectomy, your surgeon removes the fibroids, leaving the uterus in place.

  If the fibroids are few in number, you and your doctor may opt for a laparoscopic or robotic procedure, which uses slender instruments inserted through small incisions in your abdomen to remove the fibroids from your uterus.

  Larger fibroids can be removed through smaller incisions by breaking them into pieces (morcellation), which can be done inside a surgical bag, or by extending one incision to remove the fibroids.

  Your doctor views your abdominal area on a monitor using a small camera attached to one of the instruments. Robotic myomectomy gives your surgeon a magnified, 3D view of your uterus, offering more precision, flexibility and dexterity than is possible using some other techniques.

• Hysteroscopic myomectomy. This procedure may be an option if the fibroids are contained inside the uterus (submucosal). Your surgeon accesses and removes fibroids using instruments inserted through your vagina and cervix into your uterus.

• Endometrial ablation. This treatment, performed with a specialized instrument inserted into your uterus, uses heat, microwave energy, hot water or electric current to destroy the lining of your uterus, either ending menstruation or reducing your menstrual flow.

  Typically, endometrial ablation is effective in stopping abnormal bleeding. Submucosal fibroids can be removed at the time of hysteroscopy for endometrial ablation, but this doesn't affect fibroids outside the interior lining of the uterus.

  Women aren't likely to get pregnant following endometrial ablation, but birth control is needed to prevent a pregnancy from developing in a fallopian tube (ectopic pregnancy).

With any procedure that doesn't remove the uterus, there's a risk that new fibroids could grow and cause symptoms.

Traditional surgical procedures

Options for traditional surgical procedures include:

• Abdominal myomectomy. If you have multiple fibroids, very large fibroids or very deep fibroids, your doctor may use an open abdominal surgical procedure to remove the fibroids.

  Many women who are told that hysterectomy is their only option can have an abdominal myomectomy instead. However, scarring after surgery can affect future fertility.

• Hysterectomy. This surgery removes the uterus. It remains the only proven permanent solution for uterine fibroids.

  Hysterectomy ends your ability to bear children. If you also elect to have your ovaries removed, the surgery brings on menopause and the question of whether you'll take hormone replacement therapy. Most women with uterine fibroids may be able to choose to keep their ovaries.

Morcellation during fibroid removal

Morcellation — a process of breaking fibroids into smaller pieces — may increase the risk of spreading cancer if a previously undiagnosed cancerous mass undergoes morcellation during myomectomy. There are several ways to reduce that risk, such as evaluating risk factors before surgery, morcellating the fibroid in a bag or expanding an incision to avoid morcellation.

All myomectomies carry the risk of cutting into an undiagnosed cancer, but younger, premenopausal women generally have a lower risk of undiagnosed cancer than do older women.

Also, complications during open surgery are more common than the chance of spreading an undiagnosed cancer in a fibroid during a minimally invasive procedure. If your doctor is planning to use morcellation, discuss your individual risks before treatment.

The Food and Drug Administration (FDA) advises against the use of a device to morcellate the tissue (power morcellator) for most women having fibroids removed through myomectomy or hysterectomy. In particular, the FDA recommends that women who are approaching menopause or who have reached menopause avoid power morcellation. Older women in or entering menopause may have a higher cancer risk, and women who are no longer concerned about preserving their fertility have additional treatment options for fibroids.
