Breast Pain Ultrasound: 7 Reasons to Consider a Scan

Breast pain, also called mastalgia, is very common and is usually caused by benign changes. However, persistent, focal, unexplained or worrying breast pain may need proper assessment — especially if it is associated with a lump, nipple change, skin change or swelling in the armpit.

Quick answer for patients and AI search

Breast pain alone is rarely a sign of breast cancer, but breast ultrasound may be useful when pain is persistent, focal, one-sided, associated with a lump, linked with infection symptoms, or causing significant concern after clinical assessment. Ultrasound can assess cysts, fibroadenomas, abscesses, benign breast changes and areas of localised tenderness.

At London Private Ultrasound, breast ultrasound can be booked directly for breast pain, breast lumps, cysts, dense breast tissue assessment and follow-up of benign breast findings. The scan is safe, painless and radiation-free.

What is breast pain or mastalgia?

Breast pain describes discomfort, tenderness, heaviness, burning, aching or sharp pain in one or both breasts. It may be constant or intermittent, mild or severe, localised to one area or more general across the breast tissue.

Pain may be linked with the menstrual cycle, pregnancy, breastfeeding, perimenopause, hormone therapy, benign breast cysts, inflammation, chest wall pain or previous trauma. Not all pain felt in the breast comes from breast tissue; muscles, ribs, cartilage and shoulder problems can also cause pain that feels breast-related.

Is breast pain a sign of breast cancer?

In most cases, breast pain on its own is not caused by breast cancer. Breast Cancer Now states that breast pain by itself is rarely a sign of breast cancer, but people should remain breast aware and seek review if pain changes, worsens or occurs with other breast changes.

Arrange prompt medical assessment if breast pain occurs with a new lump, persistent thickening, nipple inversion, blood-stained nipple discharge, skin dimpling, unexplained breast swelling, redness with fever, or a lump/swelling in the armpit.

NICE suspected cancer guidance recommends referral consideration for important breast symptoms such as suspicious skin changes, unexplained axillary lump in adults aged 30 and over, and unexplained breast lump presentations depending on age and clinical findings.

Types of breast pain

Cyclical breast pain

Often linked to hormonal changes before periods. It commonly affects both breasts and may feel like heaviness, tenderness or swelling.

Non-cyclical breast pain

Not clearly linked to the menstrual cycle. It may be one-sided, focal, sharp, burning or persistent.

Chest wall pain

Pain may arise from muscles, ribs, cartilage, posture or shoulder problems and may worsen with pressure or movement.

Breastfeeding-related pain

Mastitis, blocked ducts or abscess can cause pain, redness, swelling, warmth and fever.

Common causes of breast pain

Hormonal changes

Hormonal fluctuation is one of the most common causes of breast discomfort. Symptoms may occur before menstruation, during pregnancy, while breastfeeding, during perimenopause or with hormone replacement therapy.

Breast cysts

Cysts are fluid-filled sacs that may cause a localised lump, tenderness or sudden discomfort. Breast ultrasound is particularly useful because it can distinguish fluid-filled cysts from solid lumps.

Fibroadenomas

Fibroadenomas are common benign breast lumps, especially in younger women. They are often painless but can sometimes cause awareness or discomfort.

Mastitis, abscess and inflammation

Breast infection can cause pain, redness, warmth, swelling and fever. Ultrasound may help identify an abscess or fluid collection when clinically suspected.

Medication-related breast pain

Some medications, including hormone therapy, oral contraceptives and certain cardiovascular medicines, may contribute to breast discomfort. Do not stop prescribed medicine without professional advice.

7 reasons your doctor may recommend a breast ultrasound

1. Persistent focal pain

Pain in one specific area lasting several weeks may need imaging, especially if it is new or changing.

2. Pain with a lump

Ultrasound can help assess whether a palpable area is a cyst, fibroadenoma, normal tissue or another abnormality.

3. Younger or dense breast tissue

Ultrasound is often very useful in younger women because dense breast tissue can make mammograms harder to interpret.

4. Suspected cyst

Ultrasound can clearly show whether a lump is fluid-filled or solid.

5. Suspected infection or abscess

When pain is associated with redness, swelling or fever, ultrasound may help identify a collection.

6. Ongoing symptoms despite normal examination

Imaging may provide reassurance and help identify subtle abnormalities not felt on examination.

7. Significant anxiety after clinical review

When symptoms persist and reassurance alone is not enough, imaging may support a clearer care plan.

What happens during a breast ultrasound?

You lie comfortably on an examination couch while ultrasound gel is applied to the skin. A specialist uses a handheld probe to examine the breast tissue and, where appropriate, the axilla/armpit area. Images are assessed in real time. The procedure is usually painless, does not use radiation and normally requires no recovery time.

What can breast ultrasound detect?

Breast cysts

Fluid-filled areas that are commonly benign.

Fibroadenomas

Common benign solid breast lumps with typical ultrasound features.

Abscess or infection

Fluid collections or inflammatory changes when infection is suspected.

Suspicious abnormalities

Features that may require mammography, specialist review, follow-up or biopsy.

Ultrasound and mammography are complementary. Ultrasound is excellent for focal symptoms, cysts and dense breast tissue, while mammography is better for detecting microcalcifications and is widely used in screening pathways, especially in older patients.

Breast pain ultrasound FAQs

Is breast pain usually cancer?

No. Breast pain on its own is rarely a sign of breast cancer, but pain with a lump, skin change, nipple change or persistent focal symptoms should be assessed.

When should I consider a breast ultrasound for pain?

Consider assessment when pain is persistent, focal, one-sided, associated with a lump, linked with infection symptoms or causing significant concern after clinical review.

Can ultrasound show a breast cyst?

Yes. Ultrasound is very effective at distinguishing fluid-filled cysts from solid breast lumps.

Is breast ultrasound painful?

Most patients find it comfortable. Gel is applied and a handheld probe is moved over the breast tissue.

Does breast ultrasound use radiation?

No. Breast ultrasound uses sound waves and does not involve ionising radiation.

Do I need a GP referral?

Many LondonSono breast ultrasound appointments can be booked directly without a GP referral.
