Abstract:  Endometrial cancer （ＥＣ） is the most common malignant tumor in female genital system, now the morbidity of EC is increasing gradually with a trend of attacking young adults, so the screening of precancerous lesion is increasingly important. It means we should take some examination in common people, pay attention to the lesion, and recognize the disease in time, now clinical diagnosis methods include serological examination, TVS, endometrial cytology test（ECT）, pathological diagnosis and immunohistochemical, however these inspections have their virtues and disadvantages, it′s impractical to choose one of them as a reliable way applying to general population, so it needs a lot of exploration to find a available method and put into use. When it′s necessary, we should combine some examinations to help diagnosis.
