Patient's question:
How can one determine whether the degeneration of a uterine fibroid is cystic or malignant? Can ultrasound detect this? First follow-up question: Thank you!If a uterine fibroid undergoes malignant transformation, what symptoms would it present? A uterine fibroid has grown more than double in size within a year, accompanied by occasional mild pain—could this indicate malignancy? Second follow-up question: Should a biopsy be performed first, or surgery? How likely is it for a uterine fibroid that grows unusually fast to degenerate?
Doctor's answer:
The risk of uterine fibroids transforming into malignancy is very low. According to foreign studies, the incidence rate is only 0.2%–1%, while in China it is around 0.5%. When fibroids become malignant, they are characterized by rapid growth within a short period, accompanied by increased vaginal discharge that appears serosanguineous, and irregular vaginal bleeding.
