Under what circumstances are fibroids likely to become cancerous?

Uterine fibroids can be cancerous, but it is not clear what conditions predispose them to cancer.
Uterine fibroids are benign tumors formed by the proliferation of uterine smooth muscle tissues, which are usually treated with medication or surgery and have a better prognosis. However, uterine fibroids also have a certain chance of malignant transformation, and sarcomatous transformation will occur, which is mostly seen in older patients, but it is not clear under what circumstances they are prone to become cancerous.
If the fibroid grows rapidly in a short period of time, if there is irregular vaginal bleeding or if the fibroid continues to grow after menopause, it should be considered that there is a possibility of malignant transformation of the fibroid. This situation requires timely surgical treatment, pathological examination to clarify the nature of fibroids, and further treatment if malignant transformation is determined.
Women who find uterine fibroids need to be treated under the guidance of a doctor.
