"At the ceremony, people cry or they look at their loved ones and they smile, because they're not going to come every day anymore. And they're proud of themselves, because it's something to be proud of, to finish chemo," said Maureen Brinkman, a social worker at the Proton Center. "The treatments are not easy, and no one wants to be here. The ceremony is a moment that's really significant, too, because it reflects our belief that tomorrow is going to be better."
