Health Screening in Singapore: Why People Skip the Test They Know They Should Take
A woman in her fifties once described, quite cheerfully, where her screening reminder lived. It was on the fridge, behind a magnet (a souvenir from a Hokkaido trip), and it had been there for most of a year. She knew what it was for. She could tell us, correctly, that the test was cheap and quick and that her sister had been screened at the polyclinic without any fuss. Then she said, "I know, I know. I will go." Every other woman in the group laughed, because every one of them had a version of that envelope. That laugh is, to me, the most honest data point in health screening research.
Here's the tension. Singapore has made screening cheap, local, and well advertised, and people understand why it matters. The gap that remains is not about knowing. It sits somewhere between knowing and booking, in a space full of fear, busy weeks, and a reluctance to be seen as someone who could be ill. This post looks at what fills that space, and what brands and health agencies (and the clinics that sell screening packages) can do about it.
The numbers behind the envelope on the fridge
Start with uptake. The Ministry of Health's National Population Health Survey 2024 found that 35.2 per cent of eligible women had breast cancer screening, down from 38.7 per cent in 2019. Cervical screening stood at 44.9 per cent, down from 48.2 per cent. Colorectal screening rose a little to 44.9 per cent (from 42.0 per cent in 2019). Chronic disease screening did better, at 66.4 per cent, roughly where it was before the pandemic.
Now set that against awareness. A Singapore Community Health Study analysis of 7,125 residents found that 93.6 per cent knew about mammography, while only 35.1 per cent had been screened as recommended. The data is from 2015 and 2016 (older than I'd like), but the uptake figure sits almost exactly where the 2024 survey lands a decade later. I checked that twice. Nearly everyone knows. About a third act.
And the stakes are not small. HealthHub's principal causes of death table shows cancer accounted for 26.5 per cent of deaths in Singapore in 2024, the largest single cause (pneumonia came second). A Straits Times commentary republished by the National Cancer Centre Singapore adds that cancer diagnoses among people under 40 reached 4,995 between 2019 and 2023, a 34 per cent increase on the 3,729 recorded between 2003 and 2007.
Price and awareness are mostly solved, so what is left?
Cost is the first explanation most people reach for, and I think it is mostly out of date. HealthHub's page on Healthier SG Screening (the programme formerly called Screen for Life) lists $0 for citizens enrolled in Healthier SG and $5 for other eligible citizens (less for Merdeka Generation and CHAS Blue or Orange cardholders), covering the relevant cardiovascular, cervical, and colorectal tests in one visit plus a follow-up consultation. Private groups offer the same subsidised tests at their CHAS clinics, as Raffles Medical's subsidised screening page shows, next to the fuller packages that clinics sell to people who want more.
Actually, cost has not disappeared so much as moved. The Annals Singapore review of barriers to breast cancer screening describes women who fear that a diagnosis will lead to high out-of-pocket treatment costs. The worry is about the bill that could follow a result, and a $5 test does nothing to calm it. The same review lists fear of pain and radiation, having "no time", the belief that "I'm healthy", modesty, and fatalism. Almost none of those are information problems. You cannot fix them with another poster about how early detection saves lives.
Three kinds of not now
The literature invites a demographic cut, older versus younger, or by ethnic group, and it does show differences there. In the interviews, though, why people were waiting mattered more than who was waiting. People who postpone give one of three kinds of reason, and the same person can move between them over a few years. For want of a better name, the Not Now Typology. A fourth type will probably turn up once we spend more time with men, who talk about screening very differently (when they talk about it at all).
The Not Now Typology
The Unready
Avoid the test because they fear the answer, and what a diagnosis would do to the family budget and routine.
"If got something, then how?"The Deferrers
Fully intend to go, and keep losing the booking to work, children, and parents who need them first.
"After the school holidays"The Private
Find the procedure or the conversation exposing, and would rather not be seen as someone who could be sick.
"Don't want people to worry"The Unready are the hardest group to reach, and probably the largest in cancer screening. The commentary above describes people who treat not knowing as a kind of protection, with "ignorance is bliss" as the operating principle. In our sessions they rarely say they are afraid. They say they feel fine. Feeling fine is doing a lot of work for them, and the Healthier SG guidance on detecting health issues early points out exactly why that is a poor guide, since conditions like diabetes and high blood pressure often develop without obvious symptoms.
The Deferrers are the most frustrating for a campaign manager, because they already agree with every message. What they lack is a slot. They are often the same people we meet in caregiver research on the hidden decision-maker in Singapore families, managing a parent's appointments while their own keep slipping. The Private worry less about the result than about being watched while they get it (a colleague seeing them at the clinic, a mother-in-law asking questions). For them the discomfort is social.
What people say about screening, and what is underneath
Stated reasons are real, but they are often the most socially acceptable version of something harder to say. Here is how the explanations we hear most often translate, at least in my reading of the transcripts.
| What participants say | What sits underneath |
|---|---|
| "No time lah, very busy" | Time is scarce, and the test also loses every contest with someone else's needs |
| "I feel healthy, no need" | Feeling fine is being used as a reason not to find out otherwise |
| "Screening is expensive" | The test is cheap, the fear is the cost of treatment if something is found |
| "Mammogram very painful, my friend said" | A borrowed story gives a respectable reason to avoid an exposing procedure |
| "I will go after the festive season" | A polite deferral, and often a decision already made |
That pattern (a sincere principle, a very different habit) runs through our research on why Singapore patients don't follow medical advice. It also explains why screening surveys overstate intention. People answer as the person they plan to be. Let me correct that, since it is unfair to them. They answer as the person they genuinely are on a good week, and the survey rarely catches the other weeks, a problem I wrote about in why Singapore consumer research keeps misleading brands.
The family can move the date
One finding from outside our own work keeps coming back to me. A 2022 Singapore focus group study with 33 adult children found that sons and daughters saw a role for themselves in their mothers' mammography, encouraging, reminding, and going along, and often underestimated how much influence they had. Many were also unaware of what screening actually cost. The sons found the topic awkward to raise (no surprise to anyone who has moderated a mixed group on it). That fits what we hear. The daughter who books the slot and turns up to drive moves a Deferrer more reliably than any reminder, in the groups we have run.
Health brands could take that seriously. A screening message aimed at the daughter (and, with care, the son) is a different creative brief from one aimed at the woman on the fridge, and I'm still not sure most campaigns have tried it at scale. The same logic shows up at the other end of the market, where Singapore's wellness and longevity consumers screen enthusiastically and share results with friends. For them, testing is identity. For the Unready, it is a threat.
How to research avoidance without shaming anyone
If you ask people why they haven't been screened, you are asking them to explain a small failure in front of strangers, and they will reach for the tidy answer. So we don't ask it that way. In in-depth interviews we start with the object, the reminder, the SMS, the booking page they opened and closed, and work backwards through what happened to it. In focus groups we often talk about "people like your friends" first, which gives the Private room to speak. Where the everyday friction matters most, mobile ethnography lets participants record the week when they meant to book and didn't.
Try this instead of asking about intentions: "Where is the last health reminder you received right now, physically or on your phone? Tell me the story of what happened to it." The answer usually reveals which kind of not now you are dealing with, far more honestly than asking whether the person plans to be screened.
Recruitment matters too. People who have never screened are slow to volunteer for a health study, so screening research needs careful quotas and neutral invitations, the same discipline we apply when mapping patient journeys that healthcare brands often miss. Our Singapore research case studies show how that approach carries across sensitive categories.
Knowing was never the hard part
Awareness is close to saturated, and price is largely handled for the tests that matter most. What remains is emotional, practical, and social, and each of the three kinds of not now needs a different answer. The Unready need a reason to believe a result is survivable. The Deferrers need someone to take the booking off their hands. The Private need a setting that doesn't feel like a public declaration of worry. I'm still working out which of these changes behaviour fastest. A useful test for any campaign is whether it would get that envelope out from behind the Hokkaido magnet and into a booking.

Finding out why your audience keeps postponing the screening they agree with
Awareness campaigns can't close a gap that isn't about awareness. We run in-depth interviews, focus groups, and mobile ethnography with Singapore residents to identify which kind of not now is holding your audience back, and what would actually get the appointment booked.
