Not all HPVs are associated with cervical cancer. Only so-called high-risk HPVs (more commonly known as HPV-HR for high-risk HPV, or oncogenic HPV) are screened, as they can cause cellular abnormalities leading to dysplasia*, and then cancer (it takes a few years). Today, there are more than ten HPV-HR types (16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 68). These are the ones we look for in your HPV test.
