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 (FOBT/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, screening is advised for adults aged 50 to 75 with a stool test every one to two years, and a positive result is followed by a colonoscopy.
Does a positive FOBT mean cancer? Not necessarily. It means blood has been detected in the stool and the result should be interpreted together with the person’s clinical situation and risk factors. 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.
