Included in nearly every executive health package in Singapore, and one of the clearest examples of a test that survives because it is traditional rather than because it works. For an adult with no symptoms the only question that matters is whether the film finds anything early enough to change the outcome — and for lung cancer that has been tested directly, in a very large randomised trial.
Oken MM, Hocking WG, et al. “Screening by chest radiograph and lung cancer mortality: the Prostate, Lung, Colorectal, and Ovarian (PLCO) randomized trial.” JAMA 2011;306:1865–1873 randomised 154,901 adults to annual chest radiography or usual care and found no reduction in lung cancer mortality after 13 years of follow-up. Low-dose CT — a different test entirely — does reduce lung cancer mortality in people with a heavy smoking history, which is why guidelines recommend LDCT for that group and a screening chest X-ray for nobody.

Singapore guidance
Not recommended for screening
Singapore’s national screening committee lists screening chest X-ray as not recommended for lung cancer. For heavy smokers aged 50 to 80 it recommends low-dose CT instead.

What it costs when it is wrong
- Basis
- Ionising radiation
- Severity
- Not confirmed
Uses ionising radiation. The committee lists it as not recommended for lung cancer screening but does not state a reason in the table.

Screening harm is not only a laboratory question: the committee’s own criteria advise against a test when “the screening test, or follow-up tests arising from a positive screen, are associated with significant medical risks”. Sources on overdiagnosis → · How this is graded.
FAQ
Is the Screening Chest X-ray worth doing in Singapore?
Screening Chest X-ray carries a weak evidence grade for screening adults without symptoms. It is most appropriate for not asymptomatic adults. Adults 50–80 with a heavy smoking history should ask about low-dose CT instead. It typically costs S$40–90 in Singapore. It is not recommended as a screen.
