Approximately 70 percent of gynecological consultations involving women in perimenopause or postmenopause are due to unexpected bleeding. This symptom is often seen as a temporary hormonal change or a natural part of aging. However, in gynecological practice, such explanations are not considered enough. Bleeding after menopause, even if it is light or occurs only once, always triggers a series of specific medical checks. This is because postmenopausal bleeding is the first symptom in 80 to 90 percent of endometrial cancers, a type of cancer that affects the lining of the uterus. As a result, any such bleeding must be reported to a doctor, even if it seems minor. The first step in the diagnostic process is usually a pelvic ultrasound, which measures the thickness of the endometrium, the lining of the uterus. If the endometrium is less than 4 to 5 millimeters, cancer is very unlikely. However, a thicker lining may require further tests, such as a biopsy or hysteroscopy, which allow for a more detailed examination of the uterine cavity. While most cases of postmenopausal bleeding have benign causes like vaginal atrophy, polyps, or fibroids, certain risk factors—such as being overweight, having diabetes, using tamoxifen, or having Lynch syndrome, a genetic condition that increases cancer risk—require greater medical attention. In France, postmenopausal bleeding accounts for about 5 percent of all gynecological investigations, highlighting both its frequency and the importance of a structured diagnostic approach. This vigilance is justified by the strong statistical link between postmenopausal bleeding and endometrial cancer. In most cases, this symptom is what leads to the early detection of the disease, allowing for timely treatment. Because of this, gynecologists are cautious about making a diagnosis based solely on a hormonal explanation. Delaying a proper evaluation could allow a treatable condition to progress, which is why early detection is critical. It is important to note that not every instance of postmenopausal bleeding indicates cancer. In fact, the majority of cases are due to benign conditions, which are often treatable with simple interventions. However, the risk of endometrial cancer should never be ignored without proper medical evaluation. Factors such as age, weight, and genetic predispositions can increase this risk. A dedicated organization for gynecological cancers emphasizes that more than 8 out of 10 women diagnosed with uterine cancer had previously experienced postmenopausal bleeding. This correlation reinforces the importance of promptly consulting a healthcare provider whenever such symptoms occur. As the new season begins and medical consultations resume, it is a good time to remember that any postmenopausal bleeding should be taken seriously and evaluated by a doctor.
