September 13 is recognized in the United States as National Childhood Cancer Awareness Day.
Each September, communities across the country unite for Childhood Cancer Awareness Month, a time dedicated to shining a light on the realities of pediatric cancer. This month is about raising awareness, supporting families, honoring children who are bravely fighting or who have passed and advancing research that brings hope for better treatments and brighter futures.
At the heart of this effort, Four Diamonds works year-round to conquer childhood cancer by helping children and their families through music therapy, social work, genetic counseling, clinical nutrition and other services. Fueled by the dedication and care of the community, Four Diamonds has assisted 100% of the eligible childhood cancer patients treated at Penn State Health Children’s Hospital.
In the U.S., more than 15,000 children are diagnosed with cancer every year. Childhood cancer remains one of the leading causes of death among children, yet it receives significantly less research funding compared to adult cancers. Awareness helps bridge that gap by educating communities, sparking conversations and encouraging support for lifesaving efforts.
For families, this month highlights the many emotional, financial and practical challenges that come with a diagnosis. It is also a moment to recognize the relentless dedication of doctors, nurses and researchers working toward safer, more effective treatments.
Wearing gold during September is a simple yet powerful way to show solidarity with children and families touched by cancer. It symbolizes how children are as precious as gold.
