We know that infections even from high-risk types of HPV are temporary and usually regress on their own.
We also know that even in the few cases where premalignant lesions form, these:
- Develop into cancer very slowly,
- The majority of them can be detected through preventive screening, and
- They are treatable.
Therefore, when we refer to secondary prevention, we mean finding premalignant lesions and treating them. Premalignant lesions can be detected using various methods, such as: Pap test, HPV test and colposcopy.
