- -HPV 16 and MICROINVASION
- -HPV 18
-graded on how far it moves up in the epithelium. CIN III all the way through. Associated with either HPV6,11 or 16,18 depending on the grade.

- 30% regress, 60% persist, 10% progress to carcinoma
- 20% de nuvo
- See its progression
- from low grade (lft--> to high grade)
For Cervical SCC
What is the Mean age?
What % of all cervical cancers are SCC?
Mean age is 45
80% of cervical cancers are SCC
What percent of cervical cancers are Adenocarcinomas?
What is its precursor lesion?
Is it more or less aggressive then SCC?
makes up 15% of all cervical cancers

How do you treat CIN I, II, III?
- CIN I
- -Follow-up, Ablative therapy
- CIN II/III

what are the ages for the HPV vaccine?
do we test for low risk HPV? Why?
- Recommendations (ACIP)
- -Young as 9 years old
- -Females 11-12 years old
