Currently, the incidence of cervical cancer is characterized by a younger age and high recurrence, and is the second most common malignancy in women worldwide. Every year, there are about 500,000 new cases and 280,000 people die directly or indirectly from cervical cancer. Surveys show that the incidence of cervical cancer is also increasing in Shenzhen and Hong Kong. At present, the treatment of cervical cancer is mainly a combination of surgery, radiotherapy and chemotherapy, and its healing is closely related to the clinical stage. How can we detect cervical cancer at an earlier stage? Cervical cancer screening is one of the best methods. It mainly includes: cervical HPV (human papillomavirus) test, TCT (cervical thin layer liquid-based cytology) and colposcopy. It is especially important for abnormal vaginal bleeding and vaginal bleeding after sexual intercourse. Some experts recommend that married or sexually active women should have this test once a year for early detection of cervical precancer and cervical cancer.
