Medical Radiation Exposures

Exposure to medical diagnostic tools involving radiation has increased dramatically among the U.S. population. DCEG researchers are assessing cancer risks associated with CT scan exposure in childhood. In addition, they are examining cancer risk associated with newer diagnostic radiologic examinations, such as high-dose nuclear medicine tests and fluoroscopically-guided interventional procedures. Researchers are studying radiation exposure from cancer treatment with the aim to quantify second cancers occurring among cancer survivors.

Diagnostic Radiation Exposures

Pediatric CT Scans and Cancer
A retrospective cohort study to evaluate the relationship between radiation exposure from CT scans conducted during childhood and adolescence and the subsequent development of cancer

Risk Assessment: Computer Tomography (CT) Scans and Screening Examinations
DCEG and colleagues have developed a state-of-the-art risk projection model for radiation-related lung cancer that takes into account the interaction with smoking

Breast and Other Cancers Following X-rays for Scoliosis
A study of cancer mortality and incidence risk in a cohort of female scoliosis patients

Tuberculosis Fluoroscopy
A study of site-specific cancer mortality among tuberculosis (TB) patients exposed to chest fluoroscopy

Radiation Treatment for Benign Diseases

Enlarged Tonsils
A study of individuals irradiated during childhood for benign head and neck conditions and monitored for the risk of thyroid and other cancers

Hyperthyroidism I-131 Treatment
A study that compares cancer risks in patients treated for hyperthyroidism with Iodine-131 vs. antithyroid drugs or surgery

Peptic Ulcer Study
A study of cancer risk and cardiovascular disease in patients receiving radiotherapy treatment for peptic ulcer disease

Benign Gynecological Disease and Cancer Mortality
A study to understand the risks associated with pelvic radiation

Late Effects of Radiotherapy, Chemotherapy and Other Cancer Treatment

Second Primary Cancers
DCEG investigators are actively engaged in research to address risks associated with treatment-related second cancers, lifestyle, environmental, and medical history factors, and genetic susceptibility

Multiple Primary Cancer Monograph
To identify groups of cancer survivors that are at increased risk for multiple primary cancers, investigators led an effort to provide the first comprehensive population-based analysis of the risk of subsequent cancer in the U.S., resulting in a monograph
