Famous actress Lee Won Won passed away at the age of 41. Although it had been rumored earlier that Lee Won Won suffered from gynecological tumors and underwent surgery and radiotherapy, her sudden death still shocked people. Many people think that gynecological cancers are not serious, and that they can be treated as long as the cancerous part is removed, which is not the case. There are about five types of gynecological cancers that are more common nowadays. The most difficult to detect is ovarian cancer, which is extremely harmful to women because it is very hidden and not easy to be detected, especially in the early stage, it is difficult to detect cancerous lesions by ultrasound, and by the time the patient develops the symptoms such as ascites, the cancer is usually in the advanced stage, with a high mortality rate, and it is the gynecological cancer with the greatest threat to women. Cervical cancer is the most threatening gynecological cancer to women. Since the cancerous part is located on the cervix, irregular bleeding will occur when the tumor ruptures, and sometimes sexual intercourse will also trigger bleeding, and due to such symptoms, corresponding treatment can be carried out. However, by the time irregular bleeding occurs, it is usually in the second stage, and the danger increases. Early stage of cervical cancer does not have any uncomfortable reaction, so it is necessary to have gynecological checkup once a year to detect cancer as early as possible and buy time for treatment. Cancer of the uterine corpus generally tends to appear in older menopausal women. If bleeding symptoms suddenly appear after a period of menopause (e.g., 5 years), diagnostic scraping should be performed immediately to determine whether cancerous lesions have appeared on the uterine corpus. Choriocarcinoma is a pregnancy-related cancer that is less likely to occur if there is no pregnancy. Another type of cancer is vulvar cancer, which is easier to determine. When this type of cancer appears, the patient will have some sensations, such as a foreign body or itching, etc., and the doctor can detect the cancer through biopsy. Therefore, it is important to remind everyone that gynecological cancer is not a “risk-free” cancer, and annual gynecological checkups are very necessary, as well as the need to be clean and maintain personal hygiene. In addition, women who have never given birth are more prone to cervical cancer, so they should pay special attention to their own health status and have checkups at any time.
