| 目的 调查估算江苏省乳腺X射线摄影的频度，进而估算乳腺摄影对江苏省女性人口的剂量负担，并评估乳腺摄影对江苏省各年龄组女性人口诱发乳腺癌的风险。方法 采用分层随机抽样调查的方法，通过调查30台乳腺摄影设备年检查人数和受检者年龄分布，估算全省乳腺摄影的频度，并计算乳腺摄影对女性人口的剂量负担。使用美国科学院电离辐射生物效应报告BEIR-Ⅶ中的超额归因风险（EAR）模型估算乳腺摄影检查对3个年龄组诱发乳腺癌的风险。结果 江苏省乳腺摄影检查的频度为3.77次/千人口；乳腺摄影对江苏省女性人口剂量负担为0.02 mGy/人。每次乳腺摄影检查对0~15岁组、16~40岁和>40岁3个年龄组的乳腺癌终生归因风险（LAR）分别为138/10万人、14.7/10万人和1.0/10万人。结论 乳腺摄影对人群乳腺癌诱发风险较小，但低年龄组的风险较大，提示针对低年龄乳腺摄影检查仍应慎重。 |

| 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. |
