How to get the app

The Pre Check app is an interactive breast model that shows some of the breast changes associated with breast cancer. The home screen resembles a breast and by touching the interactive screen, users can learn the 9 signs of breast cancer (eg, puckering, skin like orange peel, lumps, etc). The 'ready to self-check' screen is a guide on how to check your breasts, with detailed instructions on how to do the touch, look and check method. Users have the option of setting a self-check reminder which will send a push-notification to your phone.

✔ Interactive breast model with 9 abnormal findings. The phone vibrates when you touch an abnormal area.

✔ Information available regarding common signs of breast cancer.

✘  The app doesn’t help women make an informed choice about whether to self-screen/self-examine, with no education about the risks and the evidence arguing against the practice.

✘ The guidelines have shifted to “breast-awareness” over regular breast examination. There's no mention of breast-awareness and the differences in these approaches. Breast-awareness basically signifies being sensibly alert to what is normal for you and know what changes to look for.

✘ There are several omissions in the breast self-examination instructions:

  • No instruction is given about how to examine systematically (normally in a circular or linear fashion). Instead it just says “circular motions”.
  • There is no axillary tail in the breast model in the app (sometimes breast tissue extends into the armpit. This is called the axillary tail of the breast).
  • No instruction on hand movements with palpation (normally finger pads of 3 middle fingers).
  • No instruction on how exactly to inspect visually first. It just says “look”.
  • No instruction on feeling for lymph nodes.

Date of review: September 2023
Platform: Apple
Version: 1.3.2
Comments: Pre Check app is an interactive way to learn about the symptoms and signs of breast cancer, which also offers reminders for when to complete regular self-breast-checks. However, the app does not take current guidelines from the National Screening Unit or NZ Breast Cancer Foundation or Cancer Society of NZ into account. There is no evidence that regular self-breast examination reduces deaths from breast cancer - which calls the usefulness of this app into question. Age-appropriate mammograms (45-69 years) are the only breast-cancer screening test that have been proven to reduce breast cancer deaths, so I do not think the use of this app should be promoted.
Safety concerns: None.
New Zealand relevance: Yes.

Reviewer: Jeremy Steinberg, GP, FRNZCGP
Date of review: October 2019
Comments: This app is most useful for women in their 40s and older, to learn about some of the breast changes associated with breast cancer. This app recommends a rigorous monthly self-examination with monthly email reminders. This goes counter to the evidence and guidelines which now promote breast-awareness. The app doesn’t allow women to make an informed choice about whether to self-examine. There are associated harms with self-screening and there is no education provided about this controversial topic. Many studies have shown self-examination leads to more breast biopsies without any benefit (including no benefit following intensive instruction). There is a greater chance of having a benign breast biopsy and associated anxiety.
Safety concerns: Breast self-examination can lead to a higher rate of benign breast biopsies.
New Zealand relevance: Highly relevant – this is a New Zealand app.
