What does it mean to have endometrial hyperplasia?

Thick lining: For more details, i will refer this to our specialists in gynecology.

Overgrown lining: The lining of the uterus is called the endometrium. When it is too thick and/or overgrown, it is called hyperplasia. Frequently this is just a benign thickening but it can be atypical (abnormal) or even cancerous. Thickened lining in older women is more worrisome and should be biopsied. It is a diagnosis made by ultrasound, so it is typically found when evaluating abnormal bleeding.
