Key Takeaways
- Uterine fibroids are noncancerous growths that form in or around the uterus, and up to 80% of women will develop them by age 50.
- Doctors don't know one single cause, but estrogen and progesterone, the hormones that drive your menstrual cycle, appear to fuel fibroid growth.
- Family history, age, race, and lifestyle factors like weight and diet can all raise your risk of developing fibroids.
- Some women never notice a symptom, while others deal with heavy bleeding or pelvic pain, often because of where the fibroid sits inside the uterus.
- Small, symptom-free fibroids are usually just monitored, but fibroids that cause pain, heavy bleeding, or pressure need a doctor's evaluation.
- Athens ObGyn's board-certified physicians have provided expert diagnosis and treatment for uterine fibroids in Athens, GA, since 1955, and you can request an appointment online to talk through your symptoms and options.
What Are Uterine Fibroids and How Do They Develop?
Uterine fibroids, also called leiomyomas or myomas, are firm, noncancerous growths that develop from the muscle tissue of the uterus. They can form inside the uterine cavity, within the uterine wall, or on the outer surface of the uterus, and a single fibroid can range from pea-sized to several inches wide.
Fibroids are extremely common. Research cited by Mayo Clinic estimates that roughly 80% of women will develop at least one fibroid by age 50, though many never know it because the growths don't always cause symptoms. Fibroids are most often diagnosed in women between the ages of 20 and 40, which is also the prime reproductive age for many patients.
Hormonal and Genetic Influences on Fibroid Growth
Doctors don't yet know exactly what causes fibroids to form, but hormones clearly play a leading role. According to Mayo Clinic, estrogen and progesterone (the two main hormones that regulate your menstrual cycle) appear to promote fibroid growth, which is why fibroids tend to shrink after menopause, when hormone levels drop.
Genetics matter too. If your mother or sister has had fibroids, your own risk goes up. Researchers continue to study specific genetic changes that may make fibroid tissue grow faster in some women than others, but family history remains one of the clearest warning signs to share with your gynecologist.
Who Is Most at Risk? Age, Family History, and Lifestyle
While any woman can develop fibroids, several factors are known to raise the odds. The American College of Obstetricians and Gynecologists (ACOG) and Cleveland Clinic point to the following risk factors:
| Risk Factor | Why It Matters |
|---|---|
| Family history | Having a mother or sister with fibroids increases your own risk. |
| Age | Fibroids are most common during the reproductive years, typically ages 20-40, and usually shrink after menopause. |
| Race | Black women tend to develop fibroids earlier and have more severe symptoms than white women. |
| Early menstruation | Starting your period at a younger age is linked to a higher fibroid risk. |
| Obesity or higher BMI | Extra body weight is associated with increased estrogen levels, which may fuel fibroid growth. |
| Not having children | Women who haven't given birth appear to have a somewhat higher risk. |
If several of these factors apply to you, it doesn't mean fibroids are guaranteed. It simply means it's worth mentioning to your physician at your next well-woman exam.
Why Some Women Have Symptoms and Others Don't
Two women can have the exact same size fibroid and have completely different experiences. That's largely because symptoms depend on a fibroid's location, size, and number, not just whether it exists.
Fibroids that grow inside the uterine cavity are more likely to cause heavy or prolonged bleeding, cramping, and even fertility challenges. Fibroids that grow on the outer wall of the uterus may put pressure on nearby organs, leading to bloating, frequent urination, or constipation, without necessarily affecting your period. Meanwhile, small fibroids tucked within the muscle wall may never be noticed until they show up on a routine ultrasound.
Common symptoms to watch for include:
- Heavy or prolonged menstrual bleeding
- Bleeding between periods
- Pelvic pain or a feeling of fullness in the lower abdomen
- Frequent urination
- Pain during sex
- Low back pain or constipation
When to Monitor Your Fibroids vs. When to Seek Treatment
Not every fibroid needs treatment. Many small, symptom-free fibroids are simply monitored over time with regular checkups. However, you should schedule an evaluation with your gynecologist if you notice:
- Periods that are significantly heavier or longer than usual
- Bleeding between periods or after menopause
- Pelvic pain that interferes with daily activities
- Signs of anemia, such as fatigue, dizziness, or shortness of breath
- Trouble conceiving after trying for several months
Left unaddressed, heavy fibroid-related bleeding can lead to anemia, and larger fibroids can sometimes affect fertility or pregnancy. An accurate diagnosis, usually confirmed with a pelvic exam and imaging services, helps your physician recommend the right next step, whether that's continued monitoring, medication, or a discussion about gynecological surgery options like myomectomy.
Get Answers About Your Fibroid Symptoms
Fibroids are common, and having one doesn't automatically mean you need surgery or that something is seriously wrong. The right next step depends on your specific symptoms, the size and location of the fibroid, and your personal health goals, including whether you're planning a future pregnancy.
If you've noticed heavy periods, pelvic pain, or pressure that doesn't feel normal, Athens ObGyn's board-certified physicians can evaluate your symptoms and walk you through your options for gynecology care in Athens, GA.

Frequently Asked Questions
Can uterine fibroids go away on their own?
Fibroids typically don't disappear completely, but they often shrink significantly after menopause as hormone levels decline. Small fibroids that aren't causing symptoms may also stay stable for years without ever needing treatment.
Do all fibroids need to be treated?
No. Many fibroids are small and don't cause any symptoms, so your doctor may simply recommend monitoring them with periodic exams. Treatment becomes a conversation when fibroids cause heavy bleeding, pain, pressure symptoms, or fertility concerns.
Can I lower my risk of developing fibroids?
You can't control factors like family history, age, or race, but maintaining a healthy weight and eating a balanced diet may help manage the hormone levels linked to fibroid growth. Regular well-woman exams also help catch fibroids early, before they cause bigger problems.
Are fibroids near me a sign of cancer?
Uterine fibroids are noncancerous. It's extremely rare for a fibroid-like growth to be cancerous, and your doctor can confirm this through a physical exam and imaging if there's ever any concern.
At what age are fibroids most common?
Fibroids are most frequently diagnosed in women between ages 20 and 40, though they can develop at other ages too. Risk generally declines after menopause as estrogen and progesterone levels drop.
