what is cervical intraepithelial neoplasia (CIN)
premalignant cervical changes at transformation zone of cervix (squamo-columnar junction)
- glandular epithelium changes to squamous epithelium

CIN 1: mild dysplasia, no treatment
CIN 2: moderate dysplasia, likely to progress to cancer without treatment
CIN 3: severe dysplasia, will progress to cancer without treatment
treatment of CIN 2 + CIN 3
large loop excision of transitional zone
screening for cervical cancer
smear test
- every 3 years 25-49 year olds
- every 5 years 50-64 year olds
next step if 1st smear result inadequate
repeat smear
next steps if persistent (>3) inadequate smear results
assess by routine colposcopy
next steps if smear shows mild dyskaryosis
Test for HPV
- if negative she goes back to routine call
- if positive refer for routine colposcopy
next steps if smear shows moderate dyskaryosis
urgent colposcopy – within 2 weeks
next steps if smear shows severe dyskaryosis
urgent colposcopy – within 2 weeks
stages of cervical cancer
stage 1: confined to cervix
stage 2: Invades uterus / upper vagina
stage 3: invades pelvic wall / lower vagina
stage 4: invades bladder / rectum
