Which factor is the leading cause of abnormal uterine bleeding?

The leading cause of abnormal uterine bleeding is indeed related to endometrial issues, with endometrial cancer being a significant factor in this context. Abnormal uterine bleeding can manifest in various ways, such as heavy menstrual bleeding, intermenstrual bleeding, or postmenopausal bleeding. Endometrial cancer, which arises from the lining of the uterus, often presents with abnormal bleeding as one of its primary symptoms. This relationship underscores the importance of thoroughly evaluating any cases of abnormal bleeding to rule out malignancies or precancerous conditions.

While other factors like cervical incompetence, ovarian dysfunction, and uterine anomalies can contribute to abnormal uterine bleeding, endometrial cancer is particularly critical due to its implications for a woman's health. Identifying and addressing this condition early can significantly impact outcomes, making awareness of its potential as a cause central to the assessment of abnormal uterine bleeding.
