Ollie was diagnosed with Acute Lymphoblastic Leukemia at age 5 in 2017. Just 2 weeks after we found out we were expecting our 3rd child. It was a rough road. He was High Risk, he had anaphylactic reactions to his chemo, he became septic. There were days when I wanted to curl up and cry watching my sweet boy endure all this pain. He is so strong and I am so proud of him. It’s so frustrating to go through all of this and not know what caused his cancer. We hope this study can help other families like ours get some answers.
