When Daniel Zhang was just nine years old, his beloved grandmother was diagnosed with stage 3 pancreatic cancer. Sharing a deep bond built over playing games together, Daniel accompanied his parents to hospital appointments, watching as she bravely underwent chemotherapy. He struggled to comprehend why medical treatments designed to heal could also appear to cause such visible weakness. Years later, when his grandfather received a similar diagnosis, Daniel noticed the same look of confusion and worry on his younger sister's face.
Determined to bridge this gap in understanding, Daniel dove into medical reports and translated complex oncology concepts into language a seven-year-old could grasp. This profound act of empathy sparked an extraordinary creative journey: the invention of Tumor Tactics, an engaging educational card game designed to help children comprehend cancer biology, treatments, and scientific resilience.
Designing Tumor Tactics: Making Cancer Education Accessible
Teaming up with his classmate Zachary Tou—who also navigated a great-aunt's cancer journey—Daniel set out to channel the engaging mechanics of classic trading card games into a meaningful real-world application. Now 17 years old, the duo spent countless hours balancing fun gameplay with strict scientific accuracy.
- Core Gameplay: Players act as doctors treating lung, colon, and skin cancer tumors, racing to cure all three.
- Realistic Mechanics: Strategy involves weighing the pros and cons of treatments like chemotherapy, which requires rolling a die to determine effectiveness while managing potential side effects and missed turns.
- Scientific Depth: The game introduces critical medical concepts, including radiation therapy, immunotherapy, surgery, tumor progression, and potential recurrence.
To ensure absolute factual reliability, the young creators consulted extensive resources from renowned health organizations and sought rigorous reviews from medical professionals, including physicians, immunologists, and their own AP Biology teacher. Through nearly 20 iterations, they fine-tuned the mechanics to ensure the game remains both empowering and educational.
Empowering Communities Through Interactive Workshops
What began as a creative project has blossomed into a vibrant, student-led nonprofit organization. Daniel and Zachary now lead interactive workshops in public schools across San Diego, engaging students ranging from kindergarten through eighth grade. No prior biology background is necessary, and students frequently surprise the founders with their insightful strategies, thoughtful questions, and eagerness to share their own family stories.
- Fostering Connection: Workshops consistently conclude with open discussions, giving children a supportive space to share personal experiences with family illnesses.
- Peer-to-Peer Learning: Older students naturally grasp the game mechanics and step up to guide younger participants.
- Continuous Improvement: The creators actively collaborate with healthcare professionals at major medical institutions to refine the game's sensitivity and impact.
By transforming a painful personal challenge into an uplifting tool for community education, these inspiring teenagers are changing the conversation around health and healing, proving that empathy and creativity can light the way forward for the next generation.
