Flash Test (Mexico)


Cell Phone Photos Become Lifesavers in Fight Against Childhood Eye Cancer

Flash Test is a campaign to raise awareness about the most common eye cancer among children under five and to promote early detection by encouraging parents to take a simple photograph with a cell phone using the flash.


Retinoblastoma is the most common cancer in children under five years old. If detected in early stages, there is a 95% recovery rate. Symptoms are not obvious until it’s too late, so they are teaching Mexican Mothers to detect the illness themselves by taking a simple flash photo which reveals a “white pupil” – a sign of the disease.


By empowering Mexican mothers with a readily available tool – their cell phone flash – the campaign cuts through traditional barriers to early detection. A simple photograph can reveal a potentially life-threatening illness. This innovative approach empowers mothers to become active participants in their children’s health.
