MedicalResearch.com: What is the background for this study?
Response: While cancer risk in children with certain chromosomal defects like Down syndrome is well established, much less is known for children with birth defects where there is no known genetic cause, sometimes called non-chromosomal defects. Non-chromosomal defects, as a group, affect more children, but one of the primary challenges of understanding risk among these children is that limited sample sizes make studying specific defects, like spina bifida, more difficult.
Because of that, we gathered data from birth, birth defect, and cancer registries across Texas, Arkansas, Michigan, and North Carolina to generate a birth cohort of more than 10 million children born between 1992 and 2013. We looked at diagnoses of cancer until 18 years of age to determine differences in cancer risk between those with and without birth defects.
