Are fibroids in the uterus dangerous?
Answers: Fibroids are nearly always benign (non-cancerous) and are not generally a serious threat to the woman's health. However, they can be painful and often cause abnormally heavy menstrual periods.
Uterine fibroids can also cause fertility problems. If the woman does becomes pregnant the fibroids can complicate things a lot and may lead to a miscarriage.
