Multi-Cancer Early Screening Explained Singapore
What Is Multi-Cancer Early Screening and Who Should Consider It?
Multi-Cancer Early Screening also known as Multi-Cancer Early Detection (MCED) refers to a specialised blood test designed to look for signals of multiple cancers at the same time, often before any physical symptoms appear.
It is commonly considered by individuals who want additional cancer screening, beyond conventional tests, or those wanting a deeper and broader look at preventive health assessments.
The test works by finding tiny pieces of genetic materials that tumors release into the bloodstream, aiming to spot cancer early and pinpoint where it started in the body.
Understanding how this test works and what its limitations are can help you make better decisions about your personalised health screening journey with us.
Definition: Multi-Cancer Early Detection (MCED) is an advanced blood-based screening test designed to detect circulating tumor DNA (ctDNA), circulating tumor RNA (ctRNA) and cancer associated viral DNA in the blood to spot signs of cancer across different organs. MCED tests are intended to work alongside and not to replace established cancer screening programmes.
What Is Included in Multi-Cancer Early Screening or Multi-Cancer Early Detection (MCED)?
MCED testing typically involves several components:
- Medical consultation: A doctor reviews personal medical history, family history, and suitability for the test, followed by a written consent
- Blood sample collection: A standard blood draw blood sample is taken for laboratory analysis
- Genomic or biomarker analysis: Laboratory and computer analysis evaluates specific patterns of circulating tumour-associated signals
- Report and follow up consultation: A follow-up consultation with a doctor to explain the results
Who Should Consider Multi-Cancer Early Detection (MCED)?
- Adults aged 40 and older
- Individuals with a strong family history of cancer
- Individuals with multiple personal cancer risk factors such as smoking or long-term environmental exposure
- Individuals who want additional screening beyond routine tests
- Suitability should be determined during consultation with a doctor
Who May Not Need Multi-Cancer Early Detection (MCED)?
- Children or younger adults with low cancer risk
- Individuals who are already under investigation for cancer, or currently undergoing treatment for cancer
- Individuals with serious active infections or illnesses that might affect the results
- Individuals who prefer to follow national screening guidelines for cancer screening only
- Individuals unwilling to proceed with follow-up diagnostics tests in the event of an abnormal result
Screening decisions should be individualised after medical consultation
Benefits of Multi-Cancer Early Detection (MCED)
- Broader screening scope: Especially to help detect cancers that currently do not have standard screening tests (like pancreatic or ovarian cancer)
- Early detection: Offers the chance to catch cancer early before symptoms show up
- Risk clarification: Provides a clearer picture of your overall cancer risk
- Convenience: Testing involves a standard blood draw, compared to multiple organ specific investigations
Limitations and Risks of Multi-Cancer Early Detection (MCED)
- False alarms (false positives): The test might indicate a cancer signal when cancer is not present. This can cause unnecessary worry and lead to extra, invasive medical tests.
- Missed cancers (false negatives): The test might miss a cancer that is actually present, as many cancers may not produce detectable signals in extremely early stages.
- Additional testing required: Positive results require imaging or diagnostic procedures to confirm findings.
- Not a replacement for standard screenings: Gold standard cancer screening tests like mammograms, colonoscopies, and pap smears remain necessary.
- Not all cancer types may be detected
What Happens During the Appointment?
- Registration: The clinic will verify your identity.
- Consultation: A doctor will talk to you about your health risks, take a detailed medical and family history, and complete consent forms to make sure this test is right for you.
- Procedure: A nurse or phlebotomist will draw 1-3 tubes of blood from your arm, and you can usually leave right after the blood draw.
- Results timeline: Your report will typically be ready in two to three weeks, and your doctor will schedule a follow-up visit to discuss it with you.
How Much Does It Cost in Singapore?
Multi Cancer Early Detection tests in Singapore generally cost from $600 to $4,000. The price can vary depending on:
- Platform and extent of tests included.
- Consultation fees and follow up tests may be separate charges
- Whether it is part of a comprehensive health screening package
How Does Multi-Cancer Early Detection (MCED) Compare to Standard Cancer Screening?
fEATURE | Multi-Cancer Early Detection (MCED) | standard cancer screening |
|---|---|---|
How it is done | Single blood test | Imaging or procedure-based Eg: Ultrasound breast, Mammogram, vaginal pap test, procedure for colonoscopy |
What it covers | Checks for many cancer types at once | Focuses on one specific organ or type of cancer at a time |
Its role | An add-on to existing health checks; no national guideline. May screen for cancers not covered by national screening programmes. Typically higher sensitivity and specificity compared to traditional tumour markers. | Serves as gold standard cancer screening tests offered within the established national screening guideline, according to specific age and risk groups. |
Where to get it | Available mostly in private specialist clinics | Available in both public and private clinics |
Frequently Asked Questions
Is the Multi Cancer Early Detection test safe?
The test is very safe, as it is just a standard blood draw. You might experience mild side effects like a small bruise or soreness.
Do I need fasting for this test?
Preparation requirements depend on the specific brand of test your clinic uses. For most MCED blood tests, fasting is not strictly required. If it is done as part of a fasting health screening package, fasting is required typically for 6 to 8 hours.
Is MCED screening accurate?
MCED tests are designed to detect cancer-associated signals, but accuracy varies by cancer type and stage. They may have higher sensitivity for certain cancers and lower for others. They are not diagnostic tests and require follow-up confirmation.
What happens if my result is positive?
A positive result does not confirm cancer. Further diagnostic imaging and specialist referralare required to determine the cause of the detected signal.
Can MCED replace mammograms or colonoscopies?
No. MCED is intended to complement established screening tests. Standard screening remains the recommended method for breast, cervical, and colorectal cancer detection.
