"Even if you're in a room full of people, if you're not with another teenager losing their hair, going through what you're going through, you feel alone. We bring those kids together. We give them a common experience, and within two days, the wigs come off and they don't have to worry about their scars, their missing limbs. It just doesn't matter anymore."
