For many parents whose children have faced cancer, there are sounds you’ll never forget: The sound of the doctor’s voice when you get the diagnosis; and, after a long, difficult journey of chemotherapy, the joyful sound of an end-of-treatment bell.

The Aflac Cancer Center of Children's Healthcare of Atlanta released a video showing young cancer survivors ringing the end-of-treatment bell to celebrate completing chemotherapy treatments.

Chemotherapy can last for weeks, months, and, sometimes, years. For kids enduring treatment, chemo means things like needle pricks, nausea, vomiting, a loss of strength and hair that falls out. To mark the closing of a difficult chapter in their lives, young cancer warriors have the opportunity to ring the bell and celebrate.
