Some more info in this respect might be helpful:

A uterine fibroid is the most common benign (not cancerous) tumor of a woman’s uterus (womb). Fibroids develop with the uterine wall 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.
These growths occur in about 25% of all women and are the leading cause of hysterectomy (removal of the uterus) in the United States. Of every woman older than 35 years, 1 in 5 has a uterine fibroid. An estimated 600,000 hysterectomies (removal of the uterus) are performed in the US annually, and at least one-third are for fibroids. Medications and newer, less invasive surgery can control the growth of fibroids.
Fibroids start in the muscle tissues of the uterus. They can grow into the uterine cavity, into the thickness of the uterine wall, or on the surface of the uterus into the abdominal cavity. Although these tumors are called fibroids, this term is misleading because they consist of muscle tissue, not fibrous tissue.

This being a technical word, a doctor may explain with accuracy.
