Background: Scoliosis is a curving of the spine. It usually happens in girls when they are children and teens. Doctors often use x-rays to diagnose it. The x-rays give low radiation. This may increase the risk that those young women get cancer later in life. Researchers want to learn more about this risk. They will look data that has already been collected. Objectives: To study cancer risks of repeated low radiation from x-rays for scoliosis. Also, to study death risks related to certain scoliosis patient characteristics. These include causes, kinds of curvature, and kinds of treatment. Eligibility: Medical records of women from past scoliosis studies. Design: This U.S. Scoliosis Cohort includes more than 5,000 women who were diagnosed between 1912 and 1965. Data were collected on these women in the 1980s and 1990s. These came from medical records, radiology log books, and x-ray films. Researchers found out where participants were, including if they were dead. Some women were given a follow-up questionnaire. Researchers want to find out where participants are today. They want to identify new deaths of participants. They want to find out their causes of death. This data will be added to other databases.
