Understanding Mammograms (Breast Screening)
A mammogram is an X-ray examination of the breast used to detect early signs of cancer or other abnormalities. It’s a preventive health service that helps identify breast changes that may be too small to feel during a self-exam.
What Is a Mammogram?
A mammogram involves compressing the breast between two plates to take detailed X-ray images from different angles. This allows radiologists to detect:
Tiny calcium deposits (microcalcifications)
Tumours or lumps not yet felt manually
Changes in breast tissue density
There are two main types:
Screening Mammogram – for women without symptoms
Diagnostic Mammogram – for women with symptoms like lumps or pain
Early detection significantly increases the chance of successful treatment.
What to Expect from This Service
When you attend a mammogram appointment, you can typically expect:
A short consultation or pre-screening questionnaire
The procedure lasts about 15–30 minutes
Gentle compression of the breast during imaging (may feel uncomfortable but not painful)
Results usually within a few days
A follow-up if abnormalities are found
You’ll be asked to avoid deodorants or creams on the day to ensure image clarity.
Who Conducts This Service
Mammograms are conducted by:
Certified radiographers trained in breast imaging
Radiologists who interpret the scans
Private diagnostic clinics or NHS breast screening centres
All professionals follow strict safety and diagnostic guidelines.
Who Might Need This Service
Mammogram screening is recommended for:
Women aged 50–70 as part of the NHS breast screening programme (some start from age 47)
Women over 40 with a family history of breast cancer
Individuals experiencing breast symptoms such as lumps, discharge, or skin changes
Trans women over 50 who have been on hormones for 5+ years (case dependent)
Women under 50 with symptoms may be referred for earlier screening or ultrasound.
Types of Mammograms (If Applicable)
2D Mammography – standard imaging used in most routine screenings
3D Mammography (Tomosynthesis) – provides a more detailed, layered view of breast tissue
Digital Mammography – allows for enhanced clarity and easier image storage and sharing
Diagnostic Mammogram – for investigating specific concerns or symptoms
Your radiographer will recommend the most appropriate method based on your needs.
Risks Associated with Mammograms
Mammograms are safe, but some risks and considerations include:
Exposure to a small amount of radiation (minimised with modern machines)
Mild discomfort or breast tenderness
False positives or false negatives, which may require further testing
Overdiagnosis of conditions that may not need treatment
All screenings follow strict safety protocols to ensure minimal risk and maximum benefit.
How to Choose the Right Health Professional
When selecting a breast screening provider:
Choose NHS-approved centres or CQC-registered private clinics
Ensure radiographers are properly qualified in mammography
Check whether 3D or digital options are available
Look for short wait times and clear result turnaround policies
