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.
The next Radiation Epidemiology & Dosimetry Course will be held September 9-12, 2019, at NCI Shady Grove, Rockville, Maryland. Register for the Radiation Epidemiology & Dosimetry Course.

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
A study of site-specific cancer mortality among tuberculosis (TB) patients exposed to chest fluoroscopy
Tonsil Irradiation and Risk of Thyroid and Other Cancers
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
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
Childhood Cancer Survivor Study (CCSS)
A study of genetic susceptibility to radiotherapy among survivors of childhood cancer
Multiple Primary Cancers 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
Second primary gastrointestinal (GI) cancers
A multi-center study of second primary gastrointestinal (GI) cancers among survivors of Hodgkin lymphoma and cancers of the testis, breast, and cervix. This study comprehensively investigates the dose-response following fractionated, higher dose radiation treatment and risk of secondary, non-hematologic malignancies associated with chemotherapy.
