Breast ultrasound

Overview

A breast ultrasound is a safe, painless imaging test that uses sound waves to create pictures of the inside of your breast. It helps doctors see whether a lump or area of concern is a fluid-filled cyst (usually harmless) or a solid mass that may need further testing.

Breast ultrasound is a common test used worldwide for women (and some men) with breast symptoms or abnormal mammogram results.

It is most often used for women, especially those under 40 with dense breast tissue. It may also be used for pregnant or breastfeeding women, or for men with breast symptoms.

Symptoms

Common symptoms

• A lump or thickening in the breast
• Breast pain or tenderness
• Nipple discharge (especially if it is bloody or clear)
• Changes in breast size or shape
• Skin changes on the breast, such as dimpling or redness
• An area that looks suspicious on a mammogram

Symptoms in children

• Breast lumps in children are usually not cancer, but a breast ultrasound may be done to check a lump or unusual breast development.

Symptoms in older adults

• As people age, breast tissue becomes less dense, but breast ultrasound may still be used to follow up on mammogram findings or evaluate a new lump.

Causes

Main causes

• Breast cysts (fluid-filled sacs that are usually harmless)
• Fibroadenomas (solid, non-cancerous lumps)
• Breast infections (mastitis)
• Normal dense breast tissue that feels lumpy
• Breast cancer (rarely, but ultrasound can help detect it)

Risk factors

• Having a family history of breast cancer
• Being over 50
• Having dense breast tissue
• Previous breast biopsies or breast cancer
• Hormone replacement therapy
• Obesity

When to see a doctor

See a doctor urgently if:

• If you notice a new lump that feels hard and does not move easily
• If you have persistent breast pain that does not go away
• If you see any discharge from your nipple that is bloody or clear
• If the skin on your breast becomes red, warm, or swollen

Book a routine appointment if:

• If you are due for your regular screening mammogram
• If you have a family history of breast cancer and want to discuss screening
• If you have a breast concern that is not urgent but bothers you

Diagnosis

A breast ultrasound is usually performed by a sonographer (a specially trained technician) or a doctor. You will lie on your back with your arm raised above your head. A clear gel is spread on your breast, and a small handheld device called a transducer is moved over the skin. It sends sound waves into the breast and creates images on a computer screen. The test takes about 15 to 30 minutes.

Tests that may be done

• Mammogram (X-ray of the breast)
• Breast MRI (magnetic resonance imaging)
• Breast biopsy (taking a small sample of tissue for testing)

What to expect at your appointment

You will feel some pressure from the transducer, but it should not be painful. The test is safe for pregnant women and people with implants. Afterwards, the gel is wiped off, and you can go about your day normally. Results usually come back within a few days to a week.

Treatment

If the breast ultrasound finds a harmless cyst or normal tissue, no treatment is needed. If it finds a solid lump or something suspicious, your doctor may recommend further tests, such as a biopsy. Most breast lumps are not cancer, but if cancer is found, treatment will be discussed with you in detail.

Self-care at home

• Perform regular breast self-exams to become familiar with your normal breast tissue
• Wear a well-fitted bra that provides support
• Apply a warm compress if you have breast pain from a cyst
• Keep a healthy weight and exercise regularly

Medical treatments

If a breast ultrasound reveals a condition that needs treatment, options may include medication for infections, aspiration (draining a cyst with a thin needle), or monitoring with regular imaging. For suspicious or cancerous lumps, a biopsy will be done first. Depending on the results, treatment may involve surgery, radiation, hormone therapy, or chemotherapy. Your healthcare team will tailor the plan to your specific situation.

When is surgery considered?

Surgery may be needed if a biopsy confirms cancer or if a large cyst needs to be removed. The type of surgery depends on the size and location of the lump.

Living with this condition

After a breast ultrasound, you can return to normal activities right away. If you are awaiting results, it is normal to feel anxious. Try to stay busy and talk to loved ones about your feelings.

Lifestyle tips

• Maintain a balanced diet rich in fruits, vegetables, and whole grains
• Stay physically active – aim for at least 150 minutes of moderate exercise per week
• Limit alcohol consumption and avoid smoking
• Manage stress through relaxation techniques like deep breathing or yoga

Diet and exercise

Eating well and staying active can help your overall health. While they cannot prevent all breast problems, they may lower your risk of some conditions.

Mental health and emotional wellbeing

Waiting for test results can cause stress and worry. It is important to take care of your mental health. Talk to friends, family, or a counsellor. If you feel overwhelmed, reach out to a mental health professional.

Prevention

Not all breast conditions can be prevented, but a healthy lifestyle may lower your risk. Eating well, staying active, limiting alcohol, and not smoking are good steps. Regular breast awareness – knowing what is normal for you – can help you notice changes early.

Screening programmes

Regular screening mammograms are recommended for women starting at age 50 (or earlier if you have risk factors). Breast ultrasound is not a routine screening tool for all women, but it may be used for dense breasts or follow-up.

Complications

If left untreated

• A breast infection (mastitis) could spread and require more intensive treatment
• A benign lump (like a cyst) may grow larger and become uncomfortable
• Breast cancer, if present and not treated, can spread to other parts of the body

Long-term outlook

The outlook for most breast conditions is very good, especially when caught early. Breast ultrasound is a helpful tool that can guide next steps. If cancer is found, modern treatments offer good chances for recovery. Always seek professional medical advice for any concerns.
