May is Brain Tumor Awareness Month
We invite you to join us and the broader cancer community to “Go Gray in May” to raise awareness about brain tumors. Brain tumors are among the most common cancers in pediatrics, accounting for approximately one out of four childhood cancers.
Brain tumor survivors are one of the highest at-risk groups for suffering serious late effects from treatment, which can include second cancers, hearing loss, and significant developmental delays.
The cause of most childhood brain and spinal cord tumors is unknown, although we are learning more every year. A new 2025 study found that aggressive medulloblastomas begin to develop very early from genetic changes in highly specialized nerve cells between the first trimester of pregnancy and the end of the first year of life.
Signs and symptoms of brain tumors are not the same in every child, but may include: morning headaches or headaches that go away after vomiting; frequent nausea; vision, hearing, and speech problems; loss of balance; unusual sleepiness or change in activity level; unusual changes in personality or behavior; or seizures. In infants, an increase in the size of the head may be a warning sign. “Some children are unable to reach certain growth and development milestones, such as sitting up, walking, and talking in sentences,” according to the NIH. You should check with your child’s pediatrician if you notice these symptoms and have concerns.
Pediatric Brain Tumor Facts
Brain tumors are the second most common type of childhood cancer (after leukemia) and the leading cause of cancer deaths among children and adolescents. Over 4,000 children and teens under age 20 are diagnosed with central nervous system (CNS) tumors each year in the U.S., accounting for 25% of total cancer diagnoses in this age group.
Despite significant research progress over the last several decades, brain cancers are the leading cause of cancer deaths among children and adolescents. The survival rates for certain brain cancers remain perilously low. Today, three out of every ten childhood cancer deaths are caused by brain cancer.
Every year, approximately 300 children in the U.S. will be diagnosed with diffuse intrinsic pontine glioma (DIPG) - a brain cancer with a five-year survival rate of approximately two percent. Most children will live less than a year after a diagnosis of DIPG. DIPG primarily affects children between the ages of 5 and 10 years but can occur in younger children and teens. DIPG Awareness Day is May 17th.

How You Can Help
Follow along on social media all month with hashtags #BrainTumorTips, #GoGrayinMay, and #BTAM.
If you’re a brain tumor survivor, you can help us increase awareness by sharing your story with us. Your voice could be the one to encourage a family who is facing a new diagnosis, motivate a policymaker to take action, or inspire a generous benefactor with time or money who is looking for a cause to support.
Make a Gift: We simply can't do our important work without you. Your support makes a real and lasting impact in the lives of children with cancer and their families.
