ABSTRACT
Objective To explore the mammographic characteristics and technique in mammary tumor.Methods The mammographic materials of 200 cases with breast tumors which were confirmed by surgery, ultrasonography, biopsy or clinic follow-up were collected and analyzed retrospectively.Results Benign mammary tumors were found in 138 cases. They were the masses with round or ellipse in shape mammographically and soft clinically. In 62 cases of breast cancer, the mammogram showed irregular masses in 37 cases (59.7%), oval in 25 (40.3%), clustered tiny calcification in 32 (51.6%) and local infiltration in 4 (6.5%). The masses were hard on palpation, and their sizes were smaller on mammogram than that on palpation. Conclusion mammography is the initial modality for breast tumor, which can demonstrate main direct and indirect signs of the breast cancer, and shares high value in early diagnosis and differential diagnosis of the disease.
