Malignant tumors originating from the endometrial glands, also known as uterine body cancer, are mostly adenocarcinoma. It is one of the three major malignant tumors of female genitalia. In China, endometrial cancer is much lower than cervical cancer, but in some western developed countries, it is higher than cervical cancer and ranks first among gynecological malignant tumors. The high incidence age is 58~61 years old, accounting for about 7% of the total number of female cancers and 20%~30% of the malignant tumors of reproductive tract, and the incidence rate has been on the rise in recent years, and compared with cervical cancer, it has tended to approach or even exceed. It is related to long-term and continuous estrogen stimulation, obesity, hypertension, diabetes, infertility or sterility and menopause, and other physical factors and genetic factors. What are the early symptoms of endometrial cancer? 1. Symptoms. There is no obvious symptom in the very early stage, but vaginal bleeding, vaginal discharge and pain appear later. (1) Vaginal bleeding: It is mainly manifested as post-menopausal vaginal bleeding, and the amount is usually not much. Those who are not yet menopausal may show increased menstruation, prolonged periods or menstrual disorders. (2) Vaginal discharge: mostly bloody fluid or plasma discharge, or pus and blood discharge if combined with infection, with bad odor. About 25% of patients visit the clinic for abnormal vaginal discharge. (3) Lower abdominal pain and others: If the cancer involves the endocervix, it may cause pus accumulation in the uterine cavity and lower abdominal distension and cramp-like pain. In the late stage, corresponding symptoms such as anemia, emaciation and cachexia may appear. 2. Physical signs. Gynecological examination of endometrial cancer in early stage may have no abnormal findings. In late stage, there may be obvious enlargement of uterus and painful tenderness when combined with pus accumulation in uterine cavity, and cancerous tissues may occasionally come out from cervical canal and bleed easily when touched. When the cancer infiltrates the surrounding tissues, the uterus may be fixed or irregular nodules may be found in the parametrium. Based on the above symptoms and auxiliary examinations, the diagnosis of endometrial cancer can be confirmed. Therefore, women should always pay attention to the changes of their menstruation and the nature of vaginal discharge; once the symptoms appear, go to hospital for examination as early as possible.
