LOCAL DATA CONSIDERED IN RECOMMENDING STARTING AGE FOR COLORECTAL CANCER SCREENING

We thank Dr Desmond Wai Chun Tao for his feedback on lowering the recommended age for colorectal cancer screening (Time to consider starting colorectal cancer screening at 45, Sept 10).

When determining the national screening strategy for colorectal cancer, the Ministry of Health (MOH) considered the expert advice of the Screening Test Review Committee (STRC) on screening in Singapore.

In its latest report in February 2026, the STRC studied local epidemiological data from the Singapore Cancer Registry and noted the significantly higher incidence of colorectal cancer in those above the age of 50, compared with those in the lower age brackets. It affirmed that the starting age for colorectal cancer screening should remain at 50 for average-risk individuals.

Individuals at higher risk for developing colorectal cancer, such as those with a personal history of polyps or a family history of colorectal cancer, may benefit from more targeted screening interventions. These individuals should speak to their doctor about whether to start screening earlier.

Regardless of age, those with symptoms of colorectal cancer such as unexplained weight loss, blood in the stools, changes in bowel habits or persistent abdominal discomfort should seek medical attention promptly.

MOH will continue to monitor local epidemiological trends and review the recommendation as the evidence evolves.

As screening saves lives, we strongly encourage eligible Singaporeans to enrol in Healthier SG and go for their recommended screening regularly.
