what causes an enlarged uterus
Two conditions that often cause an enlarged uterus are fibroids and adenomyosis. Fibroids are the most common benign tumor of a womanâs uterus. They grow on the outside, inside or within the smooth muscle in the wall of the uterus. Fibroids may grow as a single tumor or in clusters. Fibroids can be as small as a pea and can grow as large as a melon.
