Uterine Fibroids

Uterine fibroids are noncancerous growths that develop in the muscular wall of the uterus. They can vary in size and may affect women differently, with some experiencing no symptoms at all. Depending on their size and location, fibroids can lead to changes in menstrual patterns and other physical effects.
