Currently, cancer registries cover only about 13% of the world’s children, leaving millions uncounted and unnoticed. Improving childhood cancer registration is especially urgent in poorer countries. The World Health Organization’s Global Initiative for Childhood Cancer is working to close this gap. In these countries, only 3 out of 10 children with cancer survive, compared with 8 out of 10 in richer countries. This stark difference stems from insufficient healthcare resources, leading to late or missed diagnoses, barriers to treatment, treatment interruptions, deaths from treatment side effects, and more relapses. To change this, we need policies based on reliable, consistent data.1 This is why creating strong, nationwide childhood cancer registries in places like Bangladesh is not just important but urgent. These registries are key tools for planning, tracking, and saving children’s lives.
