Breast screening and cancer

Breast screening means having a mammogram every 2 years to check for early signs of breast cancer, the most common cancer affecting women in New Zealand.

Screening saves lives by finding breast cancers before there are even any symptoms. Most breast cancers are curable if found and treated early before they can grow or spread.

What is a mammogram?

A mammogram is a type of x-ray. It is a digital picture that shows the inside of your breast to check for any signs of breast cancer.

During a mammogram, each breast is pressed firmly between two plates for up to a minute so clear pictures can be taken. You will be asked to undress from the waist up and offered a cape or gown to wear.

Mammograms are done at clinics and mobile units throughout New Zealand.

Early detection is your best protection.

What is BreastScreen Aotearoa?

BreastScreen Aotearoa is a free national breast screening programme that checks for early breast cancer.

The national programme currently offers free mammograms (breast x-rays) every 2 years to eligible women aged 45 to 69* who have no symptoms of breast cancer.

*This age range will be extended over time so that women can continue screening until they turn 75. Information will be added to TimeToBreastScreen.nz to explain the changes.

We are aiming for these changes to apply to women who:

  • turn 70 from 1 October 2024 (are born on or after 1 October 1954), if their screening region falls within the Nelson Marlborough district area.
  • turn 70 from 1 October 2025 (are born on or after 1 October 1955), once the age extension has been implemented in their screening regions.

Am I eligible?

You are eligible to participate in BreastScreen Aotearoa if you:

  • are a woman aged 45– 69
  • have no symptoms of breast cancer
  • have not had a mammogram in the last 12 months
  • are not pregnant or breastfeeding
  • are entitled to public health services in New Zealand1
  • have been free of breast cancer for five years.

If you are eligible, please talk with your doctor or hauora provider about your personal risk of breast cancer. Also look for any signs of breast cancer and talk with your healthcare provider as soon as possible if you notice changes to your breasts.

Joining BreastScreen Aotearoa and booking your mammograms

Benefits of breast screening

Screening saves lives

Mammograms help find cancer as early as possible by showing changes inside the breast before anything can be felt. You are more likely to survive breast cancer when cancers are found early and are small.

In New Zealand, people found to have breast cancer following screening are less likely to die from it than those who find breast cancer and are not in the screening programme. Screening has reduced deaths from breast cancer by one third2.

The majority of people who develop breast cancer have no family history of it. This is why it's important to be aware of any changes to your breasts and to have regular mammograms regardless of your family history. If you do have a family history, you may have a slightly higher risk.

Less treatment

Finding breast cancers early can also mean less treatment than if cancer is found later and is more advanced.

A proven method of finding cancer

In women aged 45 to 69, mammograms can find eight or nine out of ten cancers.

It is still important to look for any changes to your breasts between mammograms and talk to your doctor about these immediately.

Risks and harms of breast screening

Some cancers may not harm you

Mammograms can find small breast cancers that would not be found if you were not screened. Some of these cancers might never grow big enough to become life-threatening. This is true for 10% of cancers found by breast screening and is called overdiagnosis.

Because it is not possible to tell which cancers will become harmful, treatment will be offered for every cancer found. Treatment options can be discussed with your specialist.

Mammograms do not find all cancers

A mammogram may look normal even if cancer somewhere in a breast. In women 45 to 69 years old, about one or two out of ten cancers are not found by mammograms. Finding breast cancers in breasts has improved since digital mammograms were introduced. These show more detail than the old photograph (film) mammograms. Because mammograms can miss some cancers, it is important to be aware of any changes to your breasts between mammograms.

If you notice any changes to your breasts that are not normal for you, see your doctor as soon as possible. Do not wait for your mammogram. These changes may not be cancer, but you need to have them checked by your doctor.

Radiation

Mammograms expose you to a small amount of radiation, but this is unlikely to cause harm. The dose of radiation is smaller with the new digital mammography.

Pain and worry

Breast screening can be uncomfortable or painful for some women as well as worrying. You may bring a support person or member of your family with you if you would like someone with you before and after your mammogram.

Talk with your doctor, nurse or hauora provider about breast screening, and find more information at TimeToBreastScreen.nz
