Mammography
What is mammography?
Mammography is a specialised low-dose X-ray examination used to produce detailed images of breast tissue. It can reveal changes that may be difficult to feel during a physical examination.
A screening mammogram is performed to look for possible changes when there may be no symptoms, while diagnostic mammography investigates a specific concern or follows up an earlier finding.
The radiologist may recommend additional mammographic views or breast ultrasound when more information is needed. The appropriate approach depends on symptoms, age, clinical history and the referral.
What to expect
- Tell the team about breast symptoms, implants, previous surgery, prior mammograms and possible pregnancy.
- Avoid deodorant, talcum powder or lotion on the breasts and underarms on the day if advised, as these may affect image interpretation.
- Wear clothing that makes it easy to undress from the waist up.
- If previous mammograms were performed elsewhere, ask whether copies are needed for comparison.
- A radiographer will position one breast at a time on the mammography unit.
- The breast is briefly compressed to spread the tissue and obtain clear images using an appropriate radiation dose.
- You may feel pressure or discomfort during compression; tell the radiographer if it is difficult to tolerate.
- More than one view may be taken of each breast, and additional views may be needed for a particular concern.
- You can usually return to normal activities immediately after mammography.
- Temporary tenderness can occur, particularly if the breast was already sensitive.
- Additional images or ultrasound may be recommended to assess a finding more closely; this does not by itself mean that cancer is present.
- Your healthcare professional will explain the results and any recommended follow-up.
Safety and results
- Mammography uses a low dose of ionising radiation; the examination is recommended when its expected clinical value justifies it.
- Tell the team if you are pregnant or think you might be pregnant so the imaging approach can be assessed.
- Breast implants and previous surgery may require additional positioning or views.
- Compression is important for image quality, but inform the radiographer if you experience significant discomfort.
Please contact our team if you have questions about your examination or preparation instructions.
A radiologist evaluates the mammogram and documents the findings in a report. The report may recommend routine follow-up, additional mammographic views, ultrasound or another assessment depending on what is seen. Results are communicated through the referring clinician or agreed screening pathway. If further tests are recommended, your healthcare professional will explain their purpose and timing.
For questions about your findings or treatment, please speak to your referring healthcare professional.
