Review Identifies Factors Associated with Childhood Brain Tumors
Hadley, MO - Older parents, birth defects, maternal nutrition and childhood exposure to CT scans and pesticides are increasingly being associated with brain tumors in children, according to new research from the Brown School at Washington University in St. Louis.
Brain and central nervous system tumors are the second leading cause of cancer death in children.
A team of researchers, led by Kimberly Johnson, PhD, assistant professor of social work at the Brown School, a member of the Institute for Public Health and a research member of Siteman Cancer Center at Barnes-Jewish Hospital and Washington University School of Medicine, examined studies published since 2004 that analyzed the incidence of childhood brain tumors and survival in different parts of the world.
The study was published in September in Cancer Epidemiology, Biomarkers & Prevention.
The team reviewed studies that examined potential genetic, immune system, developmental and birth characteristics, as well as environmental risk factors.
Although established risk factors for childhood brain tumors remain limited to ionizing radiation exposure and certain cancer syndromes, “accumulating evidence suggests relatively consistent support for positive associations” between tumors and other factors. Continue>
