Breast Fillers and Screening: What Radiologists and Patients Should Know

Breast screening is an important health check. Injected material can complicate it. This page is part of our guide to breast fillers.

How fillers can appear

• Mammography: some materials look like dense areas, calcifications or masses
• Ultrasound: collections of gel can look like cysts, with variable appearances
• MRI: may show collections and inflammation

Appearances depend on the product, how long ago it was injected and the tissue reaction.

The risk of misinterpretation

Injected material may be mistaken for a lump or other abnormality, leading to extra tests or biopsies. It could also obscure a genuine abnormality.

What to do

• Tell the clinic and the radiologist exactly what was injected, when and where, before imaging
• Bring any documents
• Ask whether the imaging team has experience with injected breasts
• Keep up with screening recommended for your age and risk

Biopsy

If a biopsy is needed, say that you have had injections. Sampling through injected material needs careful planning.

If you do not know what was injected

Say so. Imaging and, if needed, tissue sampling can help characterise it.

For clinics

A provider should discuss screening implications before any breast injection and record the details for future reference. See breast enlargement safety for wider pre-treatment checks.
