A study has been conducted to determine the mortality experience from 1950-1977 of a cohort of women treated for tuberculosis in Canadian sanatoria between 1930 and 1952. Approximately 50 percent of these women received substantial breast tissue doses of fluoroscopic irradiation in conjunction with their treatment by artificial pneumothorax. A preliminary analysis of 23572 women known alive at the beginning of 1950 has shown a highly significant breast cancer mortality risk for those women exposed to such radiation. There is evidence of decreasing effect with increasing age at first exposure, and no increase in risk is observed until ten years after first exposure.
一项研究旨在确定1930年至1952年间在加拿大疗养院接受结核病治疗的一组女性在1950年至1977年期间的死亡情况。这些女性中约有50%在通过人工气胸进行治疗的同时接受了大量的乳房组织荧光透视照射剂量。对1950年初已知存活的23572名女性进行的初步分析表明，接受此类辐射的女性患乳腺癌的死亡风险非常高。有证据表明，首次接触时年龄越大，影响越小，并且在首次接触十年后才观察到风险增加。
