Men with low-stage testicular cancer frequently undergo intensive monitoring with serial computerized tomographic (CT) scans of the abdomen and pelvis. Data from atomic bomb survivors and workers from atomic energy sector show a significantly increased risk of cancer after radiation exposure. Serial abdominal-pelvic CT scans generate radiation doses comparable to those experienced by these people. This study will use population-based administrative data to determine the risk of secondary tumors of the abdomen and pelvis in men with testicular cancer after their initial therapy. It will also determine whether this risk is significantly associated with the amount of radiation exposure they incurred from abdominal-pelvic CT scans conducted during surveillance for recurrent disease.
