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. Crystal Mackall (USA), Professor of Pediatrics and Medicine at Stanford University, the Founding Director of the Stanford Center for Cancer Cell Therapy, and Director of the Parker Institute for Cancer Immunotherapy at Stanford.

Read her story here:

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

“I encourage each individual to ‘own your own personal narrative’. It is easy to look around and get the impression that you are somehow less prepared, less talented or have less opportunities than your colleagues but no matter where you came from or what experiences you have, I find that everyone brings attributes that can be turned into strengths given the right attitude… Be open to the twists and turns that life provides and greet them with openness, because none of us know the road we are destined to travel.”
