When women are diagnosed with uterine fibroids, one of the first concerns that often comes to mind is whether these growths could turn into cancer. It’s a natural worry—after all, fibroids and certain uterine cancers can cause similar symptoms. The good news is that fibroids are almost always noncancerous and rarely pose a life-threatening risk. Still, understanding the differences between fibroids and cancer can help you stay informed and proactive about your health.
What Are Fibroids?
Uterine fibroids are benign (noncancerous) tumors made up of muscle and fibrous tissue that develop within the wall of the uterus. They can vary in size, from as small as a seed to as large as a grapefruit, and can grow in single or multiple clusters. Most women will develop fibroids at some point in their lives, particularly during their 30s and 40s.
While fibroids are not cancer, they can still cause painful and disruptive symptoms, such as:
- Heavy or prolonged menstrual bleeding
- Pelvic pressure or bloating
- Frequent urination
- Pain during intercourse
- Lower back pain
These symptoms can significantly impact daily life, which is why treatment and early diagnosis are so important.
Can Fibroids Turn Into Cancer?
This is a question many women ask—and the good news is, fibroids almost never become cancerous. According to research, fewer than 1 in 1,000 fibroids may turn into a cancer known as leiomyosarcoma, a rare and aggressive form of uterine cancer. However, there’s no evidence that typical fibroids transform into leiomyosarcomas. Instead, these cancers appear to develop independently.
Because the symptoms of fibroids and uterine cancer can overlap—such as abnormal bleeding, pelvic pain, or rapid tumor growth—it’s essential to seek medical evaluation to confirm the diagnosis.
Signs to Watch For
Most fibroids grow slowly, if at all. But certain changes warrant a closer look from your doctor:
- Sudden, rapid growth of a fibroid
- Postmenopausal bleeding
- Pelvic pain that worsens over time
- Unexpected weight loss or fatigue
Your doctor may recommend imaging tests such as ultrasound or MRI to evaluate uterine growths and rule out cancer.
Diagnosing and Treating Fibroids
If your symptoms are due to benign fibroids, there are effective, non-surgical treatment options available. At USA Fibroid Centers, we specialize in Uterine Fibroid Embolization (UFE) — a minimally invasive outpatient procedure that shrinks fibroids by cutting off their blood supply. Unlike hysterectomy, UFE preserves your uterus and allows for faster recovery and lasting relief.
The Importance of Regular Checkups
Even though fibroids are not cancer, routine gynecological exams and early evaluation of abnormal symptoms are essential for protecting your reproductive health. Early detection ensures that any unusual growths are properly monitored—and if something more serious is developing, it can be addressed quickly.
Take Charge of Your Health
Fibroids and uterine cancer are two different conditions, but both deserve attention and care. If you’re experiencing heavy periods, pelvic pain, or a noticeable change in your menstrual cycle, don’t wait—schedule a consultation to discuss your options.
