Uterine fibroids are common and affect as much as 80% of women by the time they turn 50 years of age.1 However, most women may never even know they have fibroids because not all fibroids are symptomatic, and so they may go unnoticed. When fibroids grow larger than their blood supply parts of the fibroid can die forming calcifications. These calcifications cause the fibroid to harden and form into what is called a calcified fibroid.4 Calcification of fibroids however is more commonly seen in older or menopausal women. What is the big deal? If the fibroid is large and left untreated it is at risk for calcifying.
