Breast Cancer Study

It looks like Lubin has taken time away from his recent paper 

discediting Cohen's work to examine other radiation related health 

effects.

We evaluated breast cancer mortality through 1997 among 69 525 female 

radiologic technologists who were certified in the United States from 

1926 through 1982 and who responded to our questionnaire. Risk of 

breast cancer mortality was examined according to work history and 

practices and was adjusted for known risk factors. Breast cancer 

mortality risk was highest among women who were first employed as 

radiologic technologists prior to 1940 (relative risk [RR] = 2.92, 

95% confidence interval [CI] = 1.22 to 7.00) compared with risk of 

those first employed in 1960 or later and declined with more recent 

calendar year of first employment (P for trend =.002). Breast cancer 

mortality risk increased with increasing number of years of 

employment as a technologist prior to 1950 (P for trend =.018). 

However, risk was not associated with the total number of years a 

woman worked as a technologist. Technologists who first performed 

fluoroscopy (RR = 1.69, 95% CI = 1.02 to 3.11) and multifilm 

procedures (RR = 1.87, 95% CI = 1.04 to 3.34) before 1950 had 

statistically significantly elevated risks compared with 

technologists who first performed these procedures in 1960 or later. 

The high risks of breast cancer mortality for women exposed to 

occupational radiation prior to 1950 and the subsequent decline in 

risk are consistent with the dramatic reduction in recommended 

radiation exposure limits over time.
