Tests to diagnose

You have a colposcopy if you've had an abnormal result from your cervical screening test, or you have symptoms that could be caused by cervical cancer.

Some women might have a cone biopsy as a treatment for abnormal cervical cells, or to help diagnose cervical cancer.


A colposcopy is a test to have a look at the cervix in detail. The doctor or specialist nurse takes samples of any abnormal areas.


LLETZ stands for large loop excision of the transformation zone. This is the most common treatment for abnormal cervical cells. 

Cone biopsy

A cone biopsy is a small operation to remove a cone shaped piece of tissue from your cervix.
