I am trying to find out some information on fibroid tumors and the increase in size and if i should be worried. ?

Seek Gyn guidance: Fibroids are benign tumors of the uterus which are common as you get closer to menopause. Most of them are asymptomatic.if they are causing symptoms of pain or excessive bleeding, your gynecologist can assess your situation and advice you either some medical treatment or surgical removal.There are some new treatments using vascular embolisation which may be easier than surgical removal.

Not unless very fast: 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.
