What are the Causes of Fibroid Tumors?
Fibroid tumors, also called uterine fibroid tumors, are non-cancerous growths that form inside and on the wall of the uterus. Fibroid tumors are more common after the age of 30 and in African-American women. One in five women have fibroid tumors during their childbearing years, according to the National Institute of Health. The hormone estrogen seems to play a part in the cause of fibroid tumors.
