| 中文摘要: |
| Objectives To research whether prolonged or repeated low level ionizing radiation can induce female breast cancer or not and to investigate other risk factors related to breast cancer risk,a nested case control study was done.Methods 30 cases of breast cancers were enrolled in the study,4 normal persons were selected from X-ray workers as controls to match each case.Logistic regression model was used for risk analysis.Results ①Accumulative breast dose is a significant risk factor,odds ratio(OR) between two dose levels (10c Gy) is 1.73(95%CI=1.05—2.84).②ORs of other two factors,obesity and family history of breast cancer,are 4.07(P = 0.01) and 26.67(P =0.024) respectively.③Interaction may exist between occupational X-ray exposure and obesity or non lactation.Conclusions Long time and low level occupational X-ray exposure may relate to excess risk of female breast cancer among medical diagnostic X-ray workers.Family history of breast cancer and obesity are also the significant risk factors of the cancer.The existence of obesity and non lactation may enhance the effect of radiation induced breast cancer. |
