Overview
Pap Smear
Cervical dysplasia that is seen on a Pap smear is called squamous intraepithelial lesion (SIL). These changes may be graded as:
- Low-grade (LSIL)
- High-grade (HSIL)
- Possibly cancerous (malignant)
If a Pap smear shows abnormal cells or cervical dysplasia, further testing or monitoring will be recommended:
- Follow-up Pap smears may be recommended for mild cases
- Colposcopy-directed biopsy can confirm the condition
- Cone biopsy may be done after colposcopy
Dysplasia that is seen on a biopsy of the cervix is called cervical intraepithelial neoplasia (CIN). It is grouped into three categories:
- CIN I -- mild dysplasia
- CIN II -- moderate to marked dysplasia
- CIN III -- severe dysplasia to carcinoma in situ
Some strains of human papillomavirus (HPV) are known to cause cervical cancer. An HPV DNA test can identify the high-risk types of HPV linked to such cancer. This may be done:
- As a screening test for women over age 30
- For women of any age who have a slightly abnormal Pap test result
