Cancer screening is a vital preventive measure that can detect cancer early, often before symptoms appear. Different screening tests are designed to target specific types of cancer, improving the chances of successful treatment and recovery. Understanding the options available for cancer screening in Singapore can help you make informed decisions about your health.
Breast Cancer Screening
Mammograms
Mammograms are the primary screening tool for detecting breast cancer, particularly in women. This imaging test uses low-dose X-rays to identify abnormalities in breast tissue. Regular mammograms are recommended for women starting around age 40 to 50, with frequency increasing based on age and risk factors.
Breast MRI (for High-Risk Individuals)
For individuals with a higher risk of breast cancer, such as those with a family history or genetic predisposition, a breast MRI may be recommended. This test provides detailed images and is often used alongside mammograms to enhance detection. High-risk individuals should consult their doctor to determine the appropriate screening schedule.
Cervical Cancer Screening
Pap Smear
The Pap smear is a simple and effective test for detecting precancerous changes in the cervix. Women are advised to begin screening around age 21 and continue every three years if results are normal. This test is key to preventing cervical cancer through early intervention.
HPV Test
The HPV test identifies high-risk strains of the human papillomavirus that can lead to cervical cancer. Women over 30 may be co-tested with a Pap smear, and the frequency of testing depends on previous results. Combining these tests enhances the accuracy of cervical cancer detection.
Colorectal Cancer Screening
Colonoscopy
A colonoscopy is a comprehensive screening test for colorectal cancer. It involves examining the colon and rectum for polyps or cancerous growths using a flexible camera. Screening is typically recommended starting at age 45 to 50, with repeat tests every 10 years if results are normal.
Stool Tests (FIT, FOBT, and Stool DNA)
Non-invasive stool-based tests, such as FIT (Fecal Immunochemical Test), FOBT (Fecal Occult Blood Test), and stool DNA tests, can detect blood or DNA markers associated with colorectal cancer. These tests are usually recommended annually or every 1 to 3 years, depending on the type and individual risk factors.
Lung Cancer Screening
Low-Dose CT Scan
A low-dose CT scan is an effective tool for screening high-risk individuals for lung cancer. This test is recommended for adults aged 50 to 80 with a significant smoking history, including current and former heavy smokers. Early detection through screening can significantly improve survival rates.
Prostate Cancer Screening
PSA (Prostate-Specific Antigen) Test
The PSA test measures the level of prostate-specific antigen in the blood to detect potential prostate cancer. Screening is typically recommended starting at age 50, or earlier for those with a family history or other risk factors. Frequency is determined based on PSA levels and overall health.
Digital Rectal Exam (DRE)
The DRE is another screening method used to detect abnormalities in the prostate gland. Often performed alongside the PSA test, this physical exam helps identify changes that may indicate cancer.
Skin Cancer Screening
Full-Body Skin Exam
A full-body skin exam conducted by a dermatologist is a key screening method for skin cancer. This exam checks for abnormal moles or changes in the skin that could signal cancer. Annual screenings are recommended for individuals with fair skin, a history of sun exposure, or a family history of skin cancer.

Whether you’re considering a mammogram, colonoscopy, or any other cancer screening in Singapore, staying proactive about your health is the best way to ensure a healthier future.
