By supporting Strong Against Cancer, you’ve raised awareness for pediatric cancer immunotherapy and played an integral role in achieving incredible accomplishments for kids battling cancer. At the end of this month, Strong Against Cancer will sunset with gratitude and pride. Going forward we will grow Seattle Children’s pediatric cancer program locally, regionally and nationally under one brand, as one team. You are a part of the Strong Against Cancer team and the Seattle Children’s family. Celebrate with us. Continue to fight with us. As we move into the future, we look forward to working together to launch more trials, treat more kids with cancer and make breakthroughs possible.


Immunotherapy is the next great advancement in cancer treatment. Through cellular engineering, we enable the body’s own immune system to heal itself—without the harsh and often lifelong side effects of chemotherapy and radiation.

How Immunotherapy Works
