Early stage of endometrial cancer is more difficult to diagnose in ultrasound and less typical, and many patients may show normal ultrasound report when they have ultrasound in early stage. While in atypical cases, it may show uneven echogenicity of endometrium, slight thickening of endometrium and even nodular objects inside, but it is not enough to diagnose endometrial cancer. At this time, it should be combined with the patient’s symptoms to make a comprehensive judgment, such as irregular uterine bleeding, prolonged menstrual cycle, irregular menstruation, etc. All of the above may suggest that the endometrium may have problems and need early consultation. Combined with the above, clinicians may also recommend diagnostic scraping to confirm the presence of lesions in the uterine cavity, so annual physical examinations are very important. Many asymptomatic patients can find many problems through physical examination, while neglected symptoms can also be found in physical examination, so physical examination should not be neglected and annual physical examination is needed. Endometrial cancer not only observes the condition of endometrium, but also the surrounding tissues, such as endometrial cancer can erode to muscle layer, cervix, surrounding organs such as bladder and intestinal canal, and even lymph node metastasis can occur. Therefore, you need to observe carefully during ultrasound, and if you find abnormal uterine bleeding, prolonged menstruation and abdominal discomfort, you should consult a doctor as soon as possible.
