Q

How do fibroids form?

A

Arise from the myometrial layer of the uterine corpus or, less commonly, the uterine cervix, and may occur singly or multiply. Fibroids may remain within the muscular layer (intramural) or protrude outwardly to become subserosal in location or inwardly towards the endometrial cavity, where they become known as submucous fibroids. Subserosal and submucosal fibroids may become pedunculate
