Most people are afraid of talking about “cancer”, but they do not know that most gynecological cancers are preventable and treatable. For example, cervical cancer is an infectious disease caused by HPV infection. Even if the infection is not detected at the early stage and leads to cervical intraepithelial neoplasia, TCT (cervical fluid-based cytology) can screen out the abnormalities and further colposcopy can clarify the abnormalities, so as long as precancerous lesions are detected in time, cancer can be effectively prevented. For example, in endometrial cancer, there is always abnormal bleeding before the cancer, and timely endometrial exfoliation cytology or histological examination can detect the trend or possibility of cancer. Even if cancer occurs, as long as it is in the early stage, laparoscopic surgery will not affect the patient’s life expectancy. Thirdly, colposcopy is also able to detect precancerous lesions at an early stage. However, patients are often too shy to consult the doctor at an early stage and delay the diagnosis. Fourthly, malignant trophoblastic tumors are a group of cancers that can be easily detected, diagnosed and treated early, with a cure rate of over 80%. Fifth, the early diagnosis of ovarian and fallopian tube cancer is often made during other gynecological surgeries. Therefore, it also suggests that “pinhole laparoscopy” may be accepted by everyone.
