A fibroid is the most common growth found inside a woman’s pelvis. They occur in 20% to 30% of women over the age of 30. The fibroid is an overgrowth of the smooth muscle tissue which grows in the wall of the womb. Fibroids are also know as ‘myomas’ – from myo (muscle) and oma (new growth). A fibroid can be as small as a pea or grows larger than a grapefruit. Fibroids can occur as one single growth or multiple growths inside the womb, within the walls, or on its surfaces.
