Two tests, two different jobs
Screening means looking for colorectal cancer, or the polyps that can lead to it, in people who have no symptoms. A stool test — the faecal occult blood test (FOBT) or the faecal immunochemical test (FIT) — looks for tiny amounts of blood that cannot be seen with the naked eye, and a colonoscopy looks directly at the bowel lining and can remove many polyps at the same time.
In Malaysia, immunochemical faecal occult blood test (iFOBT) screening is offered to asymptomatic people at average risk aged 50 to 75. The repeat-test interval follows the screening programme guidance and your doctor’s assessment. A positive result requires a colonoscopy for further investigation. People at higher risk or with symptoms need a different assessment and investigation plan.
Does a positive FIT or FOBT mean cancer?
No. A positive stool blood test does not diagnose cancer. It means blood has been detected and needs follow-up. Colonoscopy is usually recommended to investigate the cause, taking your health and circumstances into account.
Can polyps be removed during colonoscopy?
Many small polyps can be removed during the procedure, depending on their size and characteristics.
If your symptoms persist or you are unsure of the cause, arrange an assessment.
