Description of myoma:

Myomas may grow as a single nodule or in clusters and may range in size from 1 mm to more than 20 cm in diameter. Myomas are the most frequently diagnosed tumor of the female pelvis and the most common reason for a woman to have a hysterectomy. Although they are often referred to as tumors, they are not cancerous.

The cause of myomas has not actually been determined, but most myomas develop in women during their reproductive years. Myomas do not develop before the body begins producing estrogen. Myomas tend to grow very quickly during pregnancy when the body is producing extra estrogen. Once menopause has begun, myomas generally stop growing and can begin to shrink due to the loss of estrogen.

Until recently, hysterectomy was the preferred option for treating symptomatic fibroids. Now, however, there are a number of uterine fibroid treatments including the noninvasive, outpatient MR guided Focused Ultrasound myoma treatment.
