Dear Members of the SIOP Women Leaders Network,

The field of Paediatric Oncology has been transformed by unstinted efforts of many exceptional women. These women have broken through the proverbial ‘glass ceilings’ and achieved great success in advancing our understanding of childhood cancer. The 2024 SIOP Almanac of Women Leaders profiles many such women leaders and seeks to celebrate and honour their contributions.


Today’s profile is of Dr. Milena Villarroel (Chile), a Paediatric Hemato-Oncologist with the Faculty of Medicine, University of Chile, and Founding Member and Chair of the Latin American Group for Pediatric Oncology GALOP.


Read her story here:


And here is Dr. Milena Villarroel’s advice to those who follow in her footsteps:

“Seize the myriad opportunities that come your way, recognizing that success is often the culmination of consistent effort over time. Change may not manifest immediately; it demands dedication and perseverance, even during moments when progress seems remote.”
