If I have fibroids can that be from a malignant tumor and not a benign tumor?

Fibroids. A uterine fibroid is the most common benign (not cancerous) tumor of a woman's uterus (womb). Fibroids are tumors of the smooth muscle that is normally found in the wall of the uterus. They can develop within the uterine wall itself or attach to it. They may grow as a single tumor or in clusters. Uterine fibroids can cause excessive menstrual bleeding, pelvic pain, and frequent urination.
Benign. Uterine fibroids are benign , not malignant but require follow up because when it is growing too large, it can cause problems with menstruation and anemia as well.
