What are the grades of HPV?

Cervical Intraepithelial Neoplasia (CIN): Abnormal changes in the cells of the cervix that are caused by infection with human papillomavirus (HPV). CIN is graded as 1 (low grade), 2 (moderate), or 3 (high grade). Cervix: The lower, narrow end of the uterus at the top of the vagina.

Can you have 2 types of HPV?

A person can be infected with more than one HPV strain at a time.

What are the three stages of HPV?

As currently conceived (FIGURE 1), the stages in cervical carcinogenesis include HPV infection; persistence, rather than clearance of the virus, linked to the development of a high-grade precursor lesion or “precancer”; and invasion.

Should I worry about CIN 2?

But some studies have suggested that CIN2 lesions often regress completely without treatment and should therefore be simply monitored instead. Some experts feel that approach could be especially important for younger women, since treating these lesions can pose a risk to future pregnancies.

Can CIN 2 go away on its own?

CIN 2 lesions often clear up on their own, but can also progress to CIN 3 lesions. CIN 3 is the most severe. It’s a very slow-growing disease, though: fewer than half of CIN 3 lesions will have become cancer within 30 years.

What is Ascus high risk HPV?

How common is it to have multiple strains of HPV?

Women underwent pap smears and HPV testing. During four years of visits, 22% of women became infected with multiple HPV types. Women with multiple HPV infections were at a clearly higher risk of developing cervical cancer than those with just one type of HPV infection.

Can HPV be positive and then negative?

HPV is a very common virus: About one quarter of women going through college will be exposed to HPV during their college years. In most cases, your body will effectively fight the HPV virus; most women with a positive HPV test will eventually have a negative test result.

What does HPV progress to?

HPV infections usually clear up without any intervention within a few months after acquisition, and about 90% clear within 2 years. A small proportion of infections with certain types of HPV can persist and progress to cervical cancer. Cervical cancer is by far the most common HPV-related disease.
