The anguish of childhood cancer has been mitigated in recent years by advances in treatment that make many cancers completely curable. However, a study published tomorrow in the Journal of the American Medical Association suggests that all the news is not good when it comes to long-term prognosis for victims of childhood cancers. Forty-four percent of adult survivors cite moderate to severe problems with anxiety, pain, and mental health. The nationwide study of more than 20,000 individuals is the largest study of long-term survivors of childhood cancer ever undertaken. Les Robison is a professor of pediatrics at the Cancer Center at the University of Minnesota. He was the lead investigator for the study. He says it's important for cancer survivors to be aware of the long-term consequences of successful cancer treatment.
