| Abstract:: |
| Objective To estimate the frequency and the collective dose to female population from mammography in Jiangsu province and evaluate the risk of breast cancer induced by mammography. Methods Mammography frequency was estimated by using stratified random sampling based on 30 mammography devices. The collective dose to female population and the lifetime attributable risk (LAR) were calculated by using an excess attributable risk (EAR) model given in the BEIR Ⅶ report. Results The mammography frequency in Jiangsu province is 3.77 per 1 000 population. The per caput dose to female from mammography in Jiangsu was 0.02 mGy. The LAR to 0-15, 16-40 and above 40-year age groups was 138, 14.7 and 1.0 per 100 000 population, respectively. Conclusions The risk of breast cancer from mammography is relatively low. However, there is still relative high risk in low age group, to which attention should be paid with respect to mammography. |
