There are three types of HPV vaccines, namely the 2-valent vaccine, the 4-valent vaccine and the 9-valent vaccine, all of which have age restrictions, with the highest age being 46 years old. However, as the defense function decreases with age, there is an age limit for cervical cancer vaccination, and annual cervical cancer screening is recommended after the age of 50. If the TCT and HPV test results are negative after 3 years of continuous screening, screening can be stopped. However, if you experience any discomfort, such as vaginal bleeding, lower abdominal pain or other corresponding symptoms or abnormal vaginal discharge, you must go to the hospital for examination.
