Endometrial cancer, also known as uterine cancer, begins in the lining of the uterus called the endometrium. It is the most common type of uterine cancer and predominantly affects women after menopause. This type of cancer can be categorized into two main types: endometrioid adenocarcinoma, which is the more common and less aggressive form, and non-endometrioid adenocarcinoma, which is rarer and typically more aggressive.
