The main manifestation of endometrial discharge is an increase in the amount of discharge, which can be watery or bloody. Sometimes, it can also appear as pus-blood-like discharge. Another main symptom of endometrial cancer is irregular vaginal bleeding. During an ultrasound, uneven echoes can be seen within the uterine cavity. The patient may also experience pain in the lower abdomen and increased menstrual flow. Therefore, if there are abnormalities in menstruation or unusual vaginal discharge, it is necessary to promptly go to the hospital for an ultrasound and gynecological examinations, and receive treatment based on the results of these tests.
