Uterine fibroids canceration rate

The risk of malignant transformation of uterine fibroids is relatively low, but there is still a certain risk.

Generally speaking, the risk of malignant transformation of uterine fibroids is roughly between 0.3% and 1.39%, and there are also data showing 0.4% to 0.8% or 3‰ to 5‰. These differences may be due to different research methods and sample sizes. However, some factors may increase the risk of malignant transformation, such as rapid enlargement of myoma in a short period of time, continued growth of myoma after menopause, etc. These conditions may indicate that the nature of myoma has changed, which requires close attention and further examination, including serum tumor markers, B-ultrasound, hysteroscopy, pathological biopsy, etc.
