Breast cancer among radiologic technologists.
- To evaluate the risk of breast cancer among women occupationally exposed to ionizing radiation.
- Case-control study.
- A health survey of 105 385 women radiologic technologists certified by the American Registry of Radiologic Technologists since 1926.
Among 79 016 respondents, 600 breast cancer cases were identified.
Each of 528 eligible subjects with breast cancer was matched to five control subjects based on age, year of certification, and follow-up time.
Main Outcome Measures
- Relative risk (RR) estimated as the relative odds ratio for breast cancer over categories of years worked as a radiologic technologist and according to personal and occupational exposure characteristics.
- Study subjects had been certified for a mean of 29 years ; 63.8% of cases and 62.6% of controls worked as radiologic technologists for 10 years or more.
- More than 50% of the reported breast cancers could be explained by established risk factors.
Employment as a radiologic technologist, however, was not found to increase the risk of breast cancer.
The contribution of prolonged exposure to relatively low doses of ionizing radiation to breast cancer risk was too small to be detectable at this time.
