Breast Ultrasound

Breast ultrasound uses sound waves to examine breast tissue and clarify many lumps or other findings.

Breast ultrasound, sometimes called a breast scan, uses a handheld transducer and sound waves to produce images. A clinician applies gel to the skin and moves the transducer over the area being assessed. Ultrasound can show whether a finding is fluid-filled, solid, or mixed and can guide a needle during sampling. It does not use ionising radiation.

You usually lie on your back or slightly turned, with one arm raised. The sonographer applies warm gel and scans the breast and nearby tissue, sometimes taking extra images of a specific lump or tender area. Gentle pressure may be used. The examination is external, and you can tell the sonographer if the area is sore. A radiologist reviews the images and may discuss whether more assessment is needed.

Ultrasound does not use ionising radiation and is generally suitable when radiation should be avoided. It is useful for focused assessment, especially when a lump can be felt, but it cannot answer every breast-imaging question. Results depend on the finding, its depth, the surrounding tissue, and the operator’s technique. A normal scan does not cancel a clinical review when a persistent change remains.

An abnormal result describes an imaging appearance; it is not automatically a diagnosis of cancer. A fluid-filled area may fit a Breast Cyst, while a solid appearance may lead to closer imaging or sampling. Depending on the finding, the clinician may recommend a Breast Biopsy or Core Needle Biopsy. A breast abscess, duct change, fibroadenoma, or fibrocystic pattern can each require a different plan.

Ultrasound is often used to investigate a focused symptom or to add detail after another examination. It can assess nearby lymph nodes and guide procedures, but it is not a universal replacement for mammography. Bring information about prior breast surgery, implants, pregnancy, and earlier imaging.

A clinician may request ultrasound for a palpable lump, focal pain, nipple or skin change, or an unclear mammogram finding. It can help assess conditions such as Breast Abscess, Duct Ectasia, Fibroadenoma, or Fibrocystic Breast Changes. The appropriate test depends on age, symptoms, examination, and any earlier images.

The usual sequence is: review the referral and symptoms; expose only the area needed; apply gel; scan the breast and relevant lymph-node regions; capture targeted images; and clean off the gel. If a biopsy is planned, the clinician explains that separate procedure and its aftercare.

There is usually no recovery period after a diagnostic ultrasound, and you can resume normal activities straight away. You may have mild tenderness from pressure if the area was already sore. If a needle procedure was performed, follow the separate dressing and activity instructions provided by the team.

Diagnostic ultrasound has no radiation exposure. Pressure from the transducer may be uncomfortable over a tender area. Some findings remain indeterminate, and dense or deep tissue can limit the view. An ultrasound may therefore lead to another imaging test, monitoring, or tissue sampling rather than an immediate answer.

A Mammogram can provide a different view of breast tissue, while biopsy removes cells or tissue for laboratory assessment. A Core Needle Biopsy may be guided by ultrasound when a solid area needs sampling. Your clinician chooses the combination based on the question the examination must answer.

Look for a breast-imaging service with clinicians who can perform targeted ultrasound and arrange biopsy when appropriate. Ask how you will receive the report, whether previous images should be brought, and who will explain an unclear result. Seek review for a persistent lump or new breast change even if an earlier scan was reassuring.
