Regarding cervical cancer screening, I personally believe that there are two levels of screening, one is free screening organized by the government and the other is opportunistic screening at outpatient self-pay. Both types of screening consider the same overall goal, but the actual benefits are not exactly the same. In the case of free screening, the government is concerned with meeting 80% of the population with limited funding, so there are many restrictions on the choice of screening methods. As a result, countries have different screening targets (because the government pays for it). For example, in most areas of China, screening is targeted at married women over 25 years of age and terminated at 65 years of age. In the 2010 and 2011 cervical cancer screening campaigns in Hubei Province and Wuhan City, the enrollment was for married women over 30 years old and under 60 years old, and most of the methods chosen were based on Pap cytology. However, opportunistic screening requires different requirements. Every patient wants to get the most accurate result by the best screening method, so there are not many restrictions on the screening age and method. I personally believe that as long as you have sex, it is necessary to undergo gynecological examination and screening, and the following groups of people should especially enhance the frequency of opportunistic screening: 1. early start of sexual life, especially before the age of 16 (or 18); 2. multiple sexual partners or sexual partners with multiple sexual partners; 3. history of multiple abortions; 4. history of HPV infection.
