HPV疫苗接种后仍需进行子宫颈癌筛查
随着HPV疫苗的普及，人们对宫颈癌的预防有了更多的了解。然而，专家提醒，即使接种了HPV疫苗，女性仍应定期进行子宫颈癌筛查。
中山大学附属第三医院妇产科学科带头人李小毛表示，HPV疫苗可以预防由高危型HPV感染引起的宫颈癌，但无法预防所有类型的宫颈癌。而且，对于很多年纪较大的女性来说，她们可能在接种疫苗前就已经感染了HPV。因此，定期筛查对于早期发现和治疗癌前病变至关重要。
李小毛指出，宫颈癌筛查的主要方法是巴氏涂片检查或人乳头瘤病毒（HPV）检测。巴氏涂片检查可以检测出宫颈细胞的异常变化，而HPV检测可以检测出高危型HPV感染。建议女性从21岁开始进行定期筛查，每3-5年一次。
对于已经接种了HPV疫苗的女性，筛查的频率可以适当延长，但仍需要定期进行。李小毛强调，接种HPV疫苗并不能完全替代筛查，因为疫苗无法预防所有类型的宫颈癌，而且疫苗的保护效果会随着时间的推移而减弱。
因此，女性在接种HPV疫苗后仍应定期进行子宫颈癌筛查。早期发现、早期治疗癌前病变可以大大降低宫颈癌的发病率和死亡率。

Cervical cancer screening is still necessary after HPV vaccination
With the popularization of the HPV vaccine, people have a better understanding of the prevention of cervical cancer. However, experts remind that even if vaccinated against HPV, women should still undergo regular cervical cancer screening.
Li Xiamao, the leader of the Department of Obstetrics andGynecology of the Third Affiliated Hospital of Sun Yat-sen University, said that the HPV vaccine can prevent cervical cancer caused by high-risk HPV infection, but it cannot prevent all types of cervical cancer. Moreover, for many older women, they may have been infected with HPV before vaccination. Therefore, regular screening is crucial for early detection and treatment of precancerous lesions.
Li Xiamao pointed out that the main methods of cervical cancer screening are Pap smear or human papillomavirus (HPV) testing. Pap smear can detect abnormal changes in cervical cells, while HPV testing can detect high-risk HPV infection. It is recommended thatwomen start regular screening from the age of 21, every 3-5 years.
For women who have been vaccinated against HPV, the frequency of screening can be appropriately extended, but it still needs to be carried out regularly. Li Xiamao emphasized that HPV vaccination cannot completely replace screening because the vaccine cannot prevent all types of cervical cancer, and the protective effect of the vaccine will weaken over time.
Therefore, women should still undergo regular cervical cancer screening after HPV vaccination. Early detection and early treatment of precancerous lesions can greatly reduce the incidence and mortality of cervical cancer.
