Myoma Cancer

Can Fibroids Turn into Cancer? – Patient Information Guide

Brief Answer

Fibroids are generally benign, and the likelihood of them turning into cancer is extremely low.

What are Fibroids?

Fibroids are benign tumors originating from the muscular layer of the uterus. They are quite common in women.

Risk of Malignant Transformation

The likelihood of fibroids turning into cancer is approximately 0.1–0.3% (1–3 per thousand). This is a very low rate.

What is Leiomyosarcoma?

Leiomyosarcoma is a rare type of cancer that develops from the muscular tissue of the uterus. It usually does not transform from a fibroid but rather arises as a separate disease from the outset.

When to Suspect?

• Rapidly growing mass
• Growth after menopause
• Severe and unexplained pain
• Suspicious findings on imaging

Diagnosis and Follow-up

• Regular gynecological examination
• Follow-up with ultrasound
• Evaluation with MRI if necessary

Clinical Reality

Most fibroids do not cause any problems and do not require treatment. Follow-up may be sufficient.

Conclusion

Fibroids are largely harmless. The risk of malignant transformation is very low, but regular check-ups should not be neglected.
