Whether to get the nine-valent cervical cancer vaccine is unrelated to cervical erosion. The nine-valent cervical cancer vaccine is generally suitable for individuals under the age of 25. Those who are not within this age range cannot receive the nine-valent vaccine. Patients with cervical erosion should first go to the hospital for cervical cancer screening, typically involving a TCT and HPV test. TCT, also known as ThinPrep cytologic test, and HPV, known as the human papillomavirus, are used to preliminarily screen for cervical cancer and precancerous lesions. Therefore, patients with cervical erosion can receive the nine-valent vaccine as long as the cervical cancer screening shows no issues and they are under the age of 25.
