Colposcopy of severely dysplastic cervix. Colposcopic image of a pre-cancerous human cervix showing severe abnormality (dysplasia,CIN 3). Dysplastic areas have been stained with dilute acetic acid,appearing pale and irregular in the dark pink,doughnut-shaped cervix (at centre). There is bleeding from the central cervical canal. The cervix is lined by multi-layered,skin- like cells (stratified squamous epithelium) which join to a single layer (simple columnar epithelium) in the canal. The pre-cancerous changes occur at this junction and may be detected by a smear. Treatment is by biopsy,surgery and/or radiotherapy | |
