Endometrial hyperplasia is a condition characterized by the thickening of the endometrium, the inner lining of the uterus. This thickening is due to an overgrowth of endometrial glands, often caused by excessive estrogen without adequate progesterone. While endometrial hyperplasia itself is not cancer, it can be a precursor to endometrial cancer, making it a condition that requires careful monitoring and management.
