There is a school of thought that fibroids do not turn cancerous and the very rare “cancerous fibroids” (leiomyosarcoma) arise independently and did not come from benign fibroids.
Even if fibroids could turn into cancer, the likelihood of this happening is extremely rare (<1%).
In the clinical setting, doctors consider it a risk factor for cancer transformation if the fibroids are found to grow in size rapidly.
However, when fibroids are removed for this reason, they are rarely found to be cancerous when tested by histopathology assessment.
