Understanding Degenerating Fibroids: Causes, Symptoms & Management

Question
I am a 49 year old, para 3 gravida 3, all NVD.  Menstrual cycle is very regular, last menstrual period August 6/05.

I had a cystocele/rectocele repair, along with PBNS in 1998; some ongoing urge incontinence.

Fibroids have been diagnosed by ultrasound.  Recent radiology report states that one fibroid "shows evidence of degeneration".  
I'm looking for more information on this.

Thanks for your assistance!


Answer
As you know, fibroids (leiomyoma uteri) are benign muscle tumors.  As the fibroid grows, it can have dimunution of blood supply, which leads to a  degenerative changes, including calcium deposits. Necrosis and cystic changes can occur. This is usually accompanied by fever and discomfort. Often, analgesics are enough to comfort you until the degenerative changes have ended. If the fibroid is becoming too large or causing too much discomfort, it can be removed surgically, either by hysterectomy or myomectomy. If the fibroid is not causing urinary or rectal symptoms, you usually can merely observe it and follow its growth with serial sonography.
