Cervical screening

Also known as a cervical smear

Cervical screening is a test that looks for abnormal changes to the cells of the neck of the uterus (cervix), before they develop into cancer.

A cervical smear involves having a sample of cells taken from the cervix and having these examined closely under a microscope. If any abnormal changes are seen, then treatment can be provided. Without treatment, some cells with abnormal changes can develop into cervical cancer.

Cervical smear tests are very important. Studies have shown that women who have cervical smear tests every three years have approximately a 90% reduction in risk of cervical cancer. 

Who should have a cervical smear test?

All women aged 20 until they turn 70 who have ever been sexually active should have regular smear tests. Women who have had a hysterectomy (removal of the uterus) need to check with their doctor or smear taker whether they still need to have cervical smear tests.

What happens during the test?

Having a smear only takes a few minutes. Some women find it a little uncomfortable, but it should not hurt.

A few cells will be collected from your cervix and placed into a liquid solution that preserves the cells for testing. This sample is sent to the laboratory where a small sample is put onto a microscope slide. Using high magnification, the cervical cells can be checked for any abnormal changes. A report is written and sent to your smear taker.

Like any screening test this process is not 100% accurate. However, it does pick up most problems at an early stage and has prevented many, many women from developing cervical cancer.

Your results & what they mean

There are a number of changes that your smear test can show. If there are any abnormalities, you will be sent a letter or contacted by your smear taker. Sometimes follow up tests are needed.

What is the cervical screening programme?

The National Cervical Screening Programme, set up in 1990, aims to reduce the number of women in New Zealand who develop cervical cancer and the number who die from it. The National Screening Unit is responsible for organising the programme, which includes health promotion, smear taking, laboratory analysis of cervical smears, cervical biopsies and management of women with abnormal smear results.
