Results For the first primary lesions,most of them were stage IIa, including 12 invasive ductal caicinoma, 5DCIS, 2 invasive lobular caicinoma, a invasive carcinoma with cribriform pattern and 1 case mixed-cell carcinoma. On FFDM, 5 had microcalcification,13 were mass, 1 showed focal high attenuation and 2 were not detected. For the second primary lesions, most of them were stage 0, including 7 invasive ductal carcinoma, 12 DCIS ,1 invasive lobular carcinoma, 1 mixed-cell carcinoma.
