Normally, the endometrium has a certain thickness. Patients with endometrial cancer usually show thickening of the endometrium, accompanied by irregular bleeding and abdominal pain. In severe cases, patients may experience excessive discharge from the half-vagina, accompanied by a fishy and foul odor. Typically, in cases of endometrial cancer, an ultrasound can reveal thickening of the endometrium and abnormal endometrial echoes, and some patients may show significant blood flow signals around the area according to reports. These signs generally suggest a high likelihood of endometrial cancer. The diagnosis of endometrial cancer typically involves undergoing a diagnostic curettage at the hospital. The tissue scrapped during this procedure is sent for pathology. Afterward, based on the pathology results, the type and nature of the endometrial cancer are determined. Therefore, the presence of endometrial cancer can generally be inferred from an ultrasound as well.
