1. Typical symptom of cervical cancer: contact bleeding from the cervix. Vaginal bleeding is an early sign of cervical cancer. In the early stage, it is mostly contact bleeding, which occurs after sexual intercourse or after gynecological examination; in the later stage, it manifests as irregular vaginal bleeding. Persistent infection (more than 2 years) with high-risk human papillomavirus (HPV) is the basic cause of cervical precancer and cervical cancer. Early childbirth, multiple births, early sexual life and multiple sexual partners are also risk factors for cervical cancer. Special tip: It is recommended to go to regular hospitals for cervical basal fluid cytology (TCT) and HPV examination after the appearance of the above symptoms. Regular gynecological checkups can detect occult cervical lesions. 2. Typical symptoms of endometrial cancer: irregular vaginal bleeding. The main symptom is irregular vaginal bleeding after menopause, and the amount is usually not much. Those who are not yet menopausal may show increased menstruation, prolonged menstruation or menstrual disorder. In addition, thickened endometrium is not necessarily a sign of malignancy, but must be diagnosed by scraping or hysteroscopy to obtain pathology. Special note: People with obesity, hypertension, infertility, delayed menopause, long-term use of estrogen, triamcinolone, or history of estrogen-increasing disease are high-risk factors for endometrial cancer. 3.Symptoms of uterine smooth muscle tumor: increased menstrual blood volume and prolonged menstrual period. Increased menstrual bleeding and prolonged menstrual period are mostly seen in large interstitial myoma and submucosal myoma. This is because the endometrial area increases due to the increase of myoma, which affects the contraction of uterus and blood vessels around myoma. Long-term increased menstrual bleeding can lead to anemia and weakness, in which case surgery should be performed promptly. Tip: Even small fibroids can be detected by ultrasound, so regular medical checkups are recommended to record the growth rate of fibroids. If the myoma increases rapidly or grows instead of shrinking after menopause, it should be alerted to the possibility of cancer and should be removed in time. 4.Symptoms of ovarian cancer: abdominal distension, poor appetite and indigestion. Continuous and gradually increasing abdominal distension, poor appetite and indigestion should alert to the possibility of ovarian cancer. Ovarian disease must be excluded when the above symptoms occur in postmenopausal women. Ovarian cancer has a certain genetic predisposition, and patients with ovarian cancer in their immediate family should raise awareness of prevention. Ovarian cancer is insidious and more than 70% of patients are already in advanced stage when they are diagnosed. Early detection and treatment can greatly prolong the survival of patients, but imaging examinations such as ultrasound and CT are also difficult to detect early stage patients. Special tip: Combined tumor marker tests such as glycoantigen (CA) 125 and human epitope protein 4 are recommended to reduce the risk of missed ovarian cancer diagnosis. If female friends have the above symptoms, they must go to regular hospitals for standardized examination and treatment. Early treatment can greatly improve the treatment effect of gynecological tumors.
