Detecting cancer early can make the difference. That’s why, in the 2025 edition of La Marató de 3Cat (a TV fundraiser marathon up to 15 hours long which raises funds for research into different medical fields every year), we decided to draw a parallel between green pixels appearing on a screen and cancer cells. As the disease worsens, the number of pixels increases. Once treated, the pixels gradually fade away until they disappear. "Detect it, fix it."
