What is posterior subserosal fibroid?

Subserous fibroid: Fibroids are benign tumors of the uterus. Subserosal fibroids are on the outside covering of the uterus. Posterior means towards the back.

Uterine back surface: Anyone can get a uterine fibroid, which is an overgrowth of muscle cells in the shape of a ball. Like moles on the skin, they come in different sizes/shapes; RARELY cancerous. You only need surgery if you have symptoms like pain/pressure/incontinence/bleeding/bloating. Size/location don't matter. Lupron (leuprolide) or embolization are ways to control w/out surgery. US follow up is very important.
