Breast abnormalities are not always easy to detect during a physical examination, particularly when they are small or located within denser breast tissue. In these situations, a breast ultrasound can serve as a secondary test that provides additional imaging detail to help assess breast lumps, areas of discomfort and suspicious findings more clearly.
At Maven Surgery, Dr Chong Chee Keong provides breast ultrasound assessment as part of a comprehensive approach to breast screening and breast health evaluation. As a breast, colorectal and general surgeon experienced in the management of breast conditions, he focuses on accurate assessment, early detection and personalised care to help patients better understand their breast health concerns and next steps.
A breast ultrasound is an imaging test that uses high-frequency sound waves, also known as sonography, to create images of the internal structures of the breast. Unlike mammograms, breast ultrasound does not use radiation. Instead, it produces real-time moving images that allow breast tissue to be assessed dynamically during the examination.
Breast ultrasound is commonly used as a secondary imaging test alongside mammograms rather than a replacement for routine mammogram screening. It is often recommended when a mammogram identifies an area requiring closer evaluation or when patients have denser breast tissue that may make mammogram interpretation more challenging.
Although both breast ultrasound and mammogram are used to assess breast health and detect abnormalities, they work differently and are suited for different purposes.
Mammogram | Breast Ultrasound |
Uses low-dose X-rays | Uses high-frequency sound waves |
Good at identifying small calcifications and subtle tissue abnormalities | Useful for distinguishing between solid masses and fluid-filled cysts |
Has difficulty differentiating between materials of a different density | Is able to differentiate between dense breast tissue and abnormalities |
Used as the primary assessment method | Typically used as a secondary or complementary method to mammograms |
Involves temporary breast compression to obtain clear images | Performed using a handheld probe moved gently over the skin |
Unsure whether a breast ultrasound or mammogram is right for you? Our experienced specialist is able to help you determine the ideal screening approach for your unique circumstances.
Contact UsDense breast tissue refers to breasts that contain a higher proportion of glandular and fibrous tissue compared to fatty tissue. This is a common finding among Asian women and is not considered abnormal. However, dense breast tissue can make breast cancer screening more challenging, particularly on mammograms.
On a mammogram, dense breast tissue appears white on the X-ray image. Breast tumours and other suspicious abnormalities can also appear white, making it harder to distinguish abnormal areas from the surrounding dense tissue. As a result, smaller abnormalities may sometimes be less visible on mammogram images alone.
Breast ultrasound helps address this limitation by using sound waves instead of X-rays to assess breast tissue differently. Unlike mammograms, ultrasound is able to better differentiate dense breast tissue from solid masses or fluid-filled cysts, allowing certain abnormalities to be seen more clearly during evaluation.

If you are seeking greater clarity about your breast health, a breast ultrasound may help provide further evaluation and reassurance.
Book a Consultation TodayBreast ultrasound is generally considered a comfortable, painless and non-invasive imaging procedure. Unlike mammograms, breast ultrasound does not involve breast compression or painful squeezing of the breast tissue during the examination.
During the procedure, patients may feel light pressure as the handheld ultrasound probe is moved gently across the skin. A conductive gel is also applied to help the ultrasound waves travel clearly through the breast tissue. The procedure is stress-free for the body and does not involve radiation exposure. Most patients are able to remain relaxed throughout the examination and return to their usual daily activities immediately afterwards.
Preparing for a breast ultrasound is generally straightforward, with no fasting or preliminary medication required. Following these few simple steps can help improve image quality and make the screening process more comfortable.
Breast ultrasound screening is performed in a comfortable outpatient setting and is designed to provide detailed real-time imaging of the breast tissue. The procedure is non-invasive and does not involve radiation exposure.
Upon arrival, patients will be guided through registration and preparation before the breast ultrasound begins. Relevant breast symptoms, previous breast imaging history and areas of concern may be reviewed to help guide the examination. Patients will then be positioned comfortably while the breast area is prepared for imaging with the application of a warm conductive gel to support clear ultrasound imaging.
A handheld device known as a transducer is moved gently across the breast and surrounding areas during the examination. The transducer emits high-frequency sound waves that create live images of the internal breast tissue on a monitor. In many cases, patients are able to view these images during the scan while the breast tissue is being assessed in real time.
The breast ultrasound is usually completed within a short period of time, with most examinations taking approximately 15–30 minutes, depending on the areas being assessed. Once the scan is completed, patients are generally able to resume their normal daily activities immediately afterwards.
After your breast ultrasound, the findings will be reviewed carefully to determine whether any further assessment or follow-up is required. In some cases, the ultrasound may confirm that a breast lump or abnormality is benign, while other findings may require additional imaging or investigation for greater clarity.
Where treatment is required, patients will also be guided through the appropriate breast care and breast cancer treatment options available at the clinic.
At Maven Surgery, your breast ultrasound results and next steps will be discussed clearly with Dr Chong Chee Keong, who provides personalised guidance based on your symptoms, imaging findings and individual breast health concerns. Patients are supported throughout the evaluation process to help them better understand their results and available care options.
When used alongside mammograms and clinical breast assessment, ultrasound imaging is able to support more detailed evaluation and fulfil certain requirements that other forms of screening cannot accomplish. This helps guide earlier investigation of potential abnormalities and allows for treatment to be pursued earlier.
At Maven Surgery, our breast care clinic in Singapore, breast ultrasound assessment and breast care are led by Dr Chong Chee Keong, a breast, colorectal and general surgeon experienced in the evaluation and management of breast conditions. Dr Chong adopts a careful and personalised approach to breast assessment, focusing on accurate imaging evaluation, clear patient communication and timely investigation of suspicious findings to support early detection and informed decision-making.
If you have noticed breast changes, require follow-up imaging or would like further assessment of your breast health concerns, book an appointment with us to discuss whether a breast ultrasound may be appropriate for you.
