Cervical cancer

In New Zealand, about 160 women develop cervical cancer each year – and about 60 die from it.

Cervical cancer is caused by some strains of the human papillomavirus (HPV). HPV is a very common virus that is passed on by sexual contact.

You can help protect yourself against cervical cancer by:

  • having the HPV immunisation (when you’re young)
  • having regular cervical smear tests as an adult, if you’ve ever been sexually active.

Cervical smears

Having regular smear tests can reduce a woman’s risk of developing cervical cancer by 90 percent.

A woman’s best protection against developing cervical cancer is having regular cervical smear tests.

A cervical smear test is a screening test to find abnormal changes in the cells of the cervix

All women who have ever been sexually active should have regular cervical smear tests from the time they turn 20 until they turn 70.

Women who have had a total hysterectomy don’t usually need to have smear tests unless advised to do so.

Cervical smears are available from general practitioners or nurses, marae-based or other Māori health centres, Pacific and women’s health centres, and Family Planning clinics. The cost of a smear test is similar to the cost of seeing a doctor or nurse. Some community organisations offer a free or low-cost service.

Changes to cells in the cervix happen very slowly – so by having regular smears, there is a very high likelihood that any abnormal cells will be found and treated long before they become cancer.

  • The National Cervical Screening Programme recommends that women have a cervical smear test every three years.
  • Women who have previously had abnormal smears may need to have them more often – if you’re unsure, ask your doctor.

HPV immunisation

Because of HPV immunisation and screening, cervical cancer is now one of the most preventable of all cancers.
  • The HPV immunisation protects young women against the two common types of HPV (types 16 and 18) that cause around 70 percent of cervical cancer.  
  • It also protects them against genital warts (types 6 and 11).

Women who have had the HPV immunisation still need to have regular cervical smears – because the vaccine doesn’t protect against all the types of HPV that can cause cervical cancer.

Where to get more information
