Last August, Caiden Steinhoff was diagnosed with medulla blastoma, the most common brain tumor in children. Following brain surgery, the Thunder Bay boy has undergone four chemotherapies, each of which wipes out his immune system.
After treatment, Caiden receives a stem cell transplant and remains in isolation to help his immune system recover. These photos were taken after his third round of chemotherapy last month.
