Summary
Breast cancer is the most common cancer among women in Singapore, yet only 30-40% attend regular mammograms. This trial enrolls 12,000 women aged 50-69 who haven't had a mammogram in two years. It compares five approaches: a simple reminder, a $10 voucher, a chance to win $5,000, a video from an influential person, and a personal concierge to schedule the appointment. The goal is to find which strategy works best to increase screening and, ultimately, save lives.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- What this could lead to
- If successful, this study could identify simple, scalable ways to double or triple mammography participation, potentially reducing breast cancer deaths in Singapore and across Asia.
- What could go wrong
- The trial tests behavioral nudges, not a medical treatment, so even if uptake rises, it may not translate into lower mortality. Results depend on cultural context and may not generalize outside Singapore.
