Breast Screening Programmes in Singapore

Breast cancer is the most commonly diagnosed cancers among women in Singapore. Early detection plays an important role in identifying breast cancer at an early stage, when treatment options are more effective and outcomes are better. Mammogram screening is the primary screening tool used to detect breast cancer before symptoms develop.

This page provides an overview of mammogram screening in Singapore, including the eligibility criteria, what to expect during screening, and the benefits and limitations of mammography. The aim is to support informed decision-making about breast health and screening.

What Is Mammogram Screening

A mammogram is a low-dose X-ray examination of the breast used to detect abnormal changes in breast tissue. Mammogram screening is offered to women who do not have symptoms of breast cancer, with the goal of identifying cancer at an early stage.

Mammograms can detect small abnormalities that may not be felt during breast self-examination or clinical examination. In many cases, breast cancers detected through screening are identified earlier than those found after symptoms appear.

Why Mammogram Screening Is Important

Mammogram screening is recommended because breast cancer may not cause noticeable symptoms in its early stages. Early detection through screening may:

• Allow cancer to be identified before it becomes advanced
• Support a wider range of treatment options
• Reduce the need for more extensive treatment in some cases
• Improve overall outcomes when breast cancer is detected early

Breast Screening in Singapore

Singapore's breast screening efforts are delivered through structured national programmes guided by evidence-based recommendations. These programmes aim to ensure accessibility, quality and consistency in breast cancer screening services.

Healthier SG Screening

Healthier SG Screening is a national screening programme by the Health Promotion Board that offers Singapore citizens health screening subsidies to encourage regular health screening and follow-up. It offers Singapore citizens heavily subsidized health checks for blood pressure, cholesterol, diabetes and cancers (breast, cervical and colorectal) at CHAS GP clinics.

Regular mammogram screening is the best defense against breast cancer, as detecting breast cancer early can lead to increased chances of survival.

Under the Healthier SG Screening, eligible Singapore citizens aged 50-69 years old can undergo subsidised breast cancer screening every two years. Women aged 40-49 years old can do so too, if their doctor deems it to be clinically appropriate.

Who Is Eligible for Mammogram Screening in Singapore

Eligibility criteria for breast cancer screening:

• Women aged 50 years and above
• Singapore Citizens or Permanent Residents
• Have not had a mammogram in the past two years
• Women aged 40-49 years old may be offered Healthier SG screening, if their doctor deems it to be clinically appropriate.

What Happens During a Mammogram

Understanding the mammogram process can help women feel more prepared and reduce anxiety about screening.

Before the Mammogram

Before the examination, you may be asked about previous breast imaging, medical history or hormone use. It is recommended to avoid using deodorant, talcum powder or lotions on the chest or underarms on the day of the mammogram, as these may affect image quality.

During the Mammogram

During the mammogram, each breast is positioned and gently compressed between two plates to obtain clear X-ray images. Compression may cause brief discomfort, but it lasts only a few seconds. The entire procedure usually takes around 15 to 20 minutes.

After the Mammogram

After the examination, you can return to normal activities immediately. Mammogram images are reviewed by trained radiologists. Your results will be posted to you in the form of a letter indicating whether your mammogram is normal or abnormal.

Understanding Mammogram Results

Most screening mammograms do not show signs of cancer.

• Normal results indicate that no suspicious abnormalities were detected
• Abnormal or inconclusive results may require additional imaging or assessment

An abnormal screening result does not necessarily mean cancer is present. Further tests are often recommended to clarify findings and ensure accurate diagnosis.

Benefits and Limitations of Mammogram Screening

While mammogram screening plays an important role in early detection, it is important to understand both its benefits and limitations.

Benefits

• Detects breast cancer before symptoms develop
• Identifies cancers at an earlier stage
• Supports timely referral and treatment planning

Limitations

• Mammograms do not detect all breast cancers
• False-positive results may occur, leading to additional tests
• Some detected cancers may grow slowly and not cause harm

Healthcare professionals consider these factors when making screening recommendations and advising individuals.

Mammogram Screening and Breast Density

Breast density refers to the proportion of dense tissue within the breast. Women with denser breast tissue may have mammograms that are more difficult to interpret, and dense tissue may slightly increase breast cancer risk.

In some cases, additional imaging such as ultrasound may be recommended based on individual factors and clinical assessment.

When Mammogram Screening May Not Be Appropriate

Mammogram screening is intended for women without breast symptoms. Women who experience any of the following breast changes should seek medical assessment, as diagnostic tests may be more appropriate than routine screening:

• A new lump
• Persistent breast pain
• Nipple discharge
• Skin changes over the breast

Making Informed Decisions About Mammogram Screening

Decisions about mammogram screening in Singapore should take into account:

• Age and overall health
• Personal or family history of breast cancer
• Individual preferences and concerns

Discussions with healthcare professionals can help women understand screening recommendations, potential benefits and limitations, and appropriate next steps.

Breast Screening as Part of Ongoing Breast Health

Mammogram screening is one component of a broader approach to breast health. It complements breast awareness, clinical evaluation when symptoms arise, and follow-up care when abnormalities are detected.

Regular screening supports early detection, but it does not replace the need to seek medical attention if breast changes occur between screening intervals.

Breast Screening Support at the National Cancer Centre Singapore

At the National Cancer Centre Singapore (NCCS), breast screening and follow-up care are supported through close collaboration with national screening programmes and specialist services. Women who require further assessment after mammogram screening may be referred for diagnostic evaluation, multidisciplinary review, and coordinated care when needed. NCCS provides access to specialist expertise, imaging, pathology, and supportive services to guide patients through diagnosis, treatment planning, and ongoing care.

Commonly Asked Questions

Is mammogram screening painful?

Some women experience brief discomfort during breast compression, but the procedure is generally well tolerated and short.

How often should mammogram screening be done?

Women aged 50 years and above in Singapore are recommended to undergo mammogram screening once every two years, unless advised otherwise by a healthcare professional.

Does a normal mammogram mean I will not get breast cancer?

A normal result means no abnormalities were detected at the time of screening. Regular screening remains important as changes can develop over time.

Can younger women undergo mammogram screening?

Routine screening is not generally recommended for younger women without risk factors. Assessment may be individualised based on medical advice.

What should I do if I miss a screening appointment?

Women who miss a screening interval are encouraged to arrange their next mammogram when appropriate, based on eligibility and medical guidance.
