Simple Breast Cysts

Simple breast cysts are a very common benign (non-cancerous) breast condition and are one of the most frequent causes of breast lumps in women. A breast cyst is a fluid-filled sac within the breast tissue that may vary in size and can sometimes become tender or noticeable, particularly during hormonal changes.

Although discovering a breast lump can understandably cause concern, simple breast cysts are not breast cancer and, in most cases, do not increase the risk of developing breast cancer.

A/Prof Farid Meybodi provides comprehensive assessment of breast lumps and breast cysts using modern imaging and evidence-based breast care to ensure accurate diagnosis and appropriate management.

What Are Breast Cysts?

Breast cysts develop when fluid collects within the breast tissue. They may occur as a single cyst or multiple cysts and are commonly seen in women between the ages of 35 and 50, although they can occur at any age.

Cysts may:

• Feel soft or firm
• Change in size over time
• Become tender or painful
• Fluctuate with hormonal changes
• Occur in one or both breasts

Some cysts are very small and detected only on imaging, while others may be large enough to feel during self-examination.

Common Symptoms

Many simple breast cysts cause no symptoms and are found incidentally on breast imaging. Others may cause:

• A smooth, mobile breast lump
• Breast tenderness or discomfort
• Localised breast pain
• Swelling or fullness within the breast
• Fluctuation in size before menstrual periods

Symptoms can vary depending on the size and location of the cyst.

Breast Assessment & Imaging

Any new breast lump or breast change should be assessed promptly to confirm the diagnosis and exclude other breast conditions.

Assessment may include:

• Clinical breast examination
• Breast ultrasound
• Mammography where appropriate
• Additional imaging if required

Ultrasound is particularly useful for distinguishing a fluid-filled cyst from a solid breast lump and is often the preferred imaging test for younger women or palpable cysts.

A/Prof Farid Meybodi works closely with experienced breast radiologists and imaging specialists to ensure accurate and timely breast assessment.

Simple vs Complex Cysts

Most breast cysts are classified as simple cysts, meaning they contain only fluid and have benign imaging features.

Occasionally, imaging may identify:

• Complicated cysts
• Complex cysts
• Cysts with internal debris or solid components

These findings may require closer follow-up, aspiration, or biopsy depending on imaging characteristics and clinical assessment.

Aspiration of Breast Cysts

If a cyst is large, painful, or causing discomfort, aspiration may be recommended. This involves using a fine needle to drain fluid from the cyst, often under ultrasound guidance.

Aspiration may help:

• Relieve discomfort or pressure
• Confirm the diagnosis
• Reduce the size of the lump

In many cases, symptoms improve immediately following drainage.

Not all cysts require aspiration, particularly if they are small and asymptomatic.

Ongoing Monitoring & Breast Health

Simple breast cysts are very common and often do not require ongoing treatment once the diagnosis is confirmed. However, patients should continue routine breast screening and seek review if they notice:

• A new breast lump
• Rapid enlargement
• Persistent pain
• Skin or nipple changes
• Recurrent or changing symptoms

Regular breast awareness and appropriate imaging remain an important part of overall breast health.

Personalised Breast Care

A/Prof Farid Meybodi provides personalised assessment and management of benign breast conditions with a focus on reassurance, accurate diagnosis, and patient-centred care.

We understand that breast symptoms can sometimes cause anxiety, and our goal is to provide clear communication, timely assessment, and compassionate support throughout every stage of investigation and follow-up.
