Precision in Cancer Screening: The Right Test for the Right Diagnosis

Cancer screening is aimed at detecting cancer early, often before symptoms appear. Early detection is crucial because it can significantly improve treatment outcomes. However, not all screening methods are the same—different types of cancer require different tests. Getting the right test for each cancer type helps avoid missed or false diagnoses, giving you the best chance of prevention and early treatment if detected. Here’s a guide to some common cancer screening methods and what they detect.
Colorectal Cancer
Colorectal cancer (CRC) is the most common cancer in Singapore, but fortunately it is also one of the most preventable forms of cancer. The Faecal Immunochemical Test (FIT) is a simple, non-invasive test that detects hidden blood in the stool, a potential early indicator of CRC and polyps. If the FIT results are abnormal, a Colonoscopy is recommended to examine the colon for any polyps or suspicious growths. This safe yet precise procedure is essential for removing polyps, which may help prevent cancer, or for detecting early-stage cancers before they spread. This allows for timely intervention and better treatment outcomes.
Breast Cancer
Breast cancer screening typically includes mammography and ultrasound, which help detect lumps or changes in your breast tissue that might not be felt during a self-exam. If these tests show something unusual, a biopsy may be required to confirm the findings. Breast self-examination is also of paramount importance, allowing for women to detect subtle changes, which should then prompt a visit to the doctor.
Cervical Cancer
For cervical cancer, the Pap smear is the standard screening method. During a routine pelvic exam, a doctor collects cells from the cervix to check for abnormalities that could potentially lead to cancer. Regular Pap smears are a critical step in preventing cervical cancer and ensuring optimal health outcomes.

Prostate Cancer
The Prostate-Specific Antigen (PSA) test measures the level of PSA in the blood, which can be elevated not only in prostate cancer but also in other prostate conditions, such as benign prostatic hyperplasia (BPH). A routine digital rectal examination and PSA testing are beneficial for males above 50 years, particularly if you have a family history of prostate cancer or other risk factors.
