Dense Breast Tissue
Dense breast tissue has more glandular and fibrous tissue and less fat. It is common, particularly in younger women, and is entirely normal. However, dense tissue appears white on a mammogram — the same colour as many abnormalities — which can make mammograms harder to interpret. It is also linked to a modestly higher breast cancer risk.
What is dense breast tissue?
Breast density describes the make-up of the breast on a mammogram. Radiologists grade it in categories from mostly fatty to extremely dense. It is not something you can feel, and it is not a disease — but it is useful information for planning your screening.
Screening with dense breasts
If you have dense breasts, 3D tomosynthesis improves detection compared with standard mammography, and adding ultrasound can find cancers that mammography may miss. Mr Ghosh will recommend a screening plan suited to your density and risk. Discuss this at the one-stop clinic.
When to seek medical advice
See a doctor promptly — or call 999 if you feel acutely unwell — if you notice any of the following:
- A new lump, even with normal recent mammogram
- Skin or nipple changes
- Blood-stained nipple discharge
- Any persistent change you can feel
Most breast changes are not cancer. But any new or persistent change should be assessed. Our one-stop breast clinic offers same-day specialist assessment.
Frequently asked questions
What does it mean to have dense breasts?
Dense breasts have a higher proportion of glandular and fibrous tissue to fat. It is common and normal, but it can make mammograms harder to read and is associated with a modestly higher breast cancer risk.
How do I know if I have dense breasts?
Breast density is assessed on a mammogram, not by how breasts feel. Your report may describe the density category.
Should I have extra screening?
For women with dense breasts, adding ultrasound — and sometimes MRI — to mammography can improve detection. Mr Ghosh can advise on a screening plan suited to you.
