Fibroids are benign tumors made
of smooth muscle cells and fibrous connective tissue. They develop in the
uterus. It is estimated that 70-80% of women will develop fibroids in
their lifetime—however, not everyone will develop symptoms or require
treatment. The most important characteristic of fibroids is that they are not
cancer, and they do not have the potential to become cancer. Studies
show us that fibroids grow at different rates, even in the same woman, and can
range from the size of a pea to the size of a watermelon.
What causes uterine fibroid tumors?
The cause of uterine
fibroids is not known, although studies demonstrate there may be a
genetic component. There is no food or external exposure that a woman can have
that can cause her to develop fibroids.
Who is at risk for uterine fibroids?
As women age their likelihood for
developing fibroids increases. Studies have demonstrated that women with a
family history are more likely to develop fibroids. Fibroids are also more
common in African American women. Obesity has also been linked to an increase
risk of fibroids. There are no foods or diets that are known to increase a
woman’s risk of developing fibroids.
What are the symptoms of uterine fibroids?
Most women with fibroids will experience no symptoms at all. However, for many women large or numerous fibroids can cause the following symptoms:
>> Heavy or prolonged periods
>> Bleeding between periods
>> Pelvic pain and pressure
>> Frequent urination
>> Low back pain
>> Pain during intercourse
>> Difficulty getting pregnant
How are uterine fibroids diagnosed?
Fibroids are most often found
during the physical exam. Your healthcare provider may feel a firm, irregular
pelvic mass during an abdominal or pelvic exam.
Other tests may include:
– Transvaginal ultrasound. This is an ultrasound performed inside the vagina to better assess if you have fibroids. It can help establish the diagnosis as the first imaging test.
– MRI. This imaging test does not use radiation, and allows your provider to gain a road map as to the size, number, and location of each of your fibroids. It is often recommended before proceeding with some surgical options.
– Saline Sonohysteragram. This is a vaginal ultrasound performed in the office while putting fluid (saline) into the uterus. By expanding the uterine cavity with this fluid your provider may be able to see if you have fibroids growing within the uterine cavity.
– Hysteroscopy. This is a surgical procedure performed to gain direct visualization of the uterine cavity. It does not visualize or treat fibroids outside the cavity.
How are uterine fibroids treated?
Since most fibroids stop growing
or may even shrink as you approach menopause, your healthcare
provider may simply suggest “watchful waiting.” With this
approach, your healthcare provider monitors your symptoms carefully to be
sure that there are no significant changes.
If your fibroids are large or
cause significant symptoms, treatment may be an option. Treatment will be
discussed with you by your healthcare provider based on your age, fertility
goals, the number and size of your fibroids, any previous fibroids treatments,
other health conditions.
What are the complications of uterine fibroids?
It is uncommon for fibroids to
cause severe health consequences. However, women can have heavy bleeding which
can lead to dangerous anemia. Rarely, large fibroids can press on the bladder
and ureter, leading to kidney damage. Other complications include infertility
and recurrent pregnancy loss.
Key points about uterine fibroids:
– Uterine fibroids are the most common tumor of the reproductive tract.
– Fibroids are not cancer.
– They do not increase a woman’s risk for uterine cancer, and they do not become cancer.
– Women who are nearing menopause are at the greatest risk for fibroids. Fibroids are most often found during a routine pelvic exam.
– Symptoms may include heavy and prolonger periods, bleeding between periods and pelvic pain.
– Fibroids are most often found during a routine pelvic exam.
– There are a variety of treatment options available, which may include watchful waiting, medicines or surgery.
