What are uterine fibroids?

  • Uterine fibroids are benign growths that develop from the muscle tissue of the uterus
    • They also are called leiomyomas or myomas
    • The size, shape, and location of fibroids can vary greatly
    • They may be present inside the uterus
    • Can be on its outer surface or within its wall, or attached to it by a stem-like structure
    • A woman may have only one fibroid or many of varying sizes
    • A fibroid may remain very small for a long time
    • May suddenly grow rapidly, or grow slowly over a number of years

Who is most likely to have fibroids?

  • Most common in women aged 30?40 years, but they can occur at any age
  • Occur more often in African American women than in white women
  • Also, fibroids occur at a younger age and grow more quickly in African American women

What are symptoms of fibroids?

  • Fibroids may have the following symptoms:
    • Changes in menstruation
      • Longer, more frequent, or heavy menstrual periods
      • Menstrual pain (cramps)
    • Vaginal bleeding at times other than menstruation
    • Anemia (from blood loss)
    • In the abdomen or lower back ranging from dull to sharp
    • Pain during sex
    • Internal pressure
      • Difficulty urinating or frequent urination
      • Constipation, rectal pain, or difficult bowel movements
    • Abdominal cramps
    • Enlarged uterus and abdomen
    • Miscarriages
    • Infertility
  • Fibroids also may cause no symptoms at all
  • Fibroids may be found during a routine pelvic exam or during tests for other problems

What complications can occur with fibroids?

  • Fibroids that are attached to the uterus by a stem may twist
    • They can cause pain, nausea, or fever
  • Fibroids that grow rapidly, or those that start breaking down, also may cause pain
    • Rarely, they can be associated with cancer
  • A very large fibroid may cause swelling of the abdomen
    • This swelling can make it hard to do a thorough pelvic exam
  • Fibroids may cause infertility, although other causes are more common
  • Other factors should be explored before fibroids are considered the cause of a couple?s infertility
  • When fibroids are thought to be a cause, many women are able to become pregnant after they are treated

How are fibroids diagnosed?

  • May be detected during a routine pelvic exam
  • Other tests may show more information about fibroids:
    • Ultrasonography
      • This uses sound waves to create a picture of the uterus and other pelvic organs
    • Hysteroscopy
      • This uses a slender device (the hysteroscope) to see the inside of the uterus
      • It is inserted through the vagina and cervix
      • This permits the doctor to see fibroids inside the uterine cavity
    • Hysterosalpingography
      • This is a special X-ray test
      • It may detect abnormal changes in the size and shape of the uterus and fallopian tubes
    • Sonohysterography
      • This is a test in which fluid is put into the uterus through the cervix
      • Ultrasonography is then used to show the inside of the uterus
      • The fluid provides a clear picture of the uterine lining
    • Laparoscopy
      • This uses a slender device (the laparoscope) to help the doctor see the inside of the abdomen
      • It is inserted through a small cut just below or through the navel
      • The doctor can see fibroids on the outside of the uterus
    • Imaging tests, such as magnetic resonance imaging and computed tomography scans
  • Some of these tests may be used to track the growth of fibroids over time.

When is treatment necessary for fibroids?

  • Women who are nearing menopause often do not require treatment
  • Signs and symptoms that may signal the need for treatment include:
    • Heavy or painful menstrual periods that cause anemia or that disrupt a woman?s normal activities
    • Bleeding between periods
    • Uncertainty whether the growth is a fibroid or another type of tumor
    • Rapid increase in growth of the fibroid
    • Infertility
    • Pelvic pain

Can medication be used to treat fibroids?

  • Drug therapy is an option
    • Medications may reduce the heavy bleeding
    • May reduce painful periods
    • They may not prevent the fibroid growth
    • Surgery is often needed later
  • Drug treatment for fibroids includes the following options:
    • Birth control pills and other types of hormonal birth control methods
      • These drugs are used to control heavy bleeding and painful periods
    • Gonadotropin-releasing hormone (GnRH) agonists
      • These drugs stop the menstrual cycle and can shrink fibroids
      • Sometimes they are used before surgery to reduce the risk of bleeding
      • GnRH agonists have many side effects so they are used for short periods
      • Once treatment stops, fibroids tend to return to previous size
    • Progestin?releasing intrauterine device
      • This option is for women with fibroids that do not distort the inside of the uterus
      • It reduces heavy and painful bleeding but does not treat the fibroids themselves

What types of surgery may be done to treat fibroids?

  • Myomectomy
    • This is the surgical removal of fibroids while leaving the uterus in place
    • Because a woman keeps her uterus, she may still be able to have children
    • Fibroids do not regrow after surgery, but new fibroids may develop
    • If they do, more surgery may be needed
  • Hysterectomy
    • This is the removal of the uterus
    • The ovaries may or may not be removed
    • This is done when other treatments have not worked or are not possible or the fibroids are very large
    • A woman is no longer able to have children after having a hysterectomy

Are there other treatments besides medication and…

  • Hysteroscopy
    • This technique is used to remove fibroids that protrude into the cavity of the uterus
    • A resectoscope is inserted through the hysteroscope
    • The resectoscope destroys fibroids with electricity or a laser beam
    • It cannot remove fibroids deep in the walls of the uterus
      • It can often control the bleeding these fibroids cause
    • This procedure can be performed as an outpatient procedure
  • Endometrial ablation
    • This procedure destroys the lining of the uterus
    • It is used to treat women with small fibroids (less than 3 centimeters)
    • There are several ways to perform endometrial ablation
      • Uterine artery embolization (UAE)
        • In this procedure, tiny particles are injected into the blood vessels that lead to the uterus
        • The particles cut off the blood flow to the fibroid and cause it to shrink
        • UAE can be performed as an outpatient procedure
  • Magnetic resonance imaging-guided ultrasound surgery
    • In this new approach, ultrasound waves are used to destroy fibroids
    • The waves are directed at the fibroids through the skin with the help of magnetic resonance imaging.
    • Studies show that women have improved symptoms up to 1 year after having the procedure
    • Whether this approach provides long-term relief is currently being studied
