1. What Is Endometrial Cancer and Where Does It Start?
Endometrial cancer, frequently termed uterine cancer, arises when cells within the endometrium, the inner lining of the uterus, undergo uncontrolled proliferation. These cells have the potential to invade other regions of the body. The uterus, a hollow organ resembling a medium-sized pear, is where a fetus develops during pregnancy. According to the American Cancer Society, the majority of uterine cancers originate in the body of the uterus, not the cervix. For free answers to pressing questions and concerns, visit WHAT.EDU.VN.
2. How Does the Uterus Function, and What Is the Endometrium’s Role?
The uterus is essential for female reproduction. During childbearing years, the ovaries release an egg monthly, prompting hormones to thicken the endometrium to prepare for pregnancy. If pregnancy doesn’t occur, the endometrial lining sheds through menstruation until menopause, when this process ceases. If you have questions about endometrial cancer or related topics, WHAT.EDU.VN offers a platform to ask and receive free answers.
3. What Are the Main Sections of the Uterus?
The uterus consists of three main sections:
- Cervix: The narrow lower section.
- Isthmus: The broad section in the middle (body of the uterus).
- Fundus: The dome-shaped top section.
If you have questions about these sections or endometrial cancer, WHAT.EDU.VN is available for free answers.
4. What Are the Layers of the Uterus?
The body of the uterus has three main layers:
- Myometrium: The outer, thick muscle layer that helps push the baby out during birth.
- Endometrium: The inner layer.
- Serosa: The outer coating of the uterus.
