title: Clinical value of mammography in diagnosis and identification of breast mass.
abstract: OBJECTIVE
  To study the effect and clinical value of mammography in the diagnosis of breast lump so as to improve the diagnosis level of breast cancer.
  
  
  METHODS
  A retrospective analysis was carried out on clinical data of 110 patients with mammary lump confirmed by pathology to study the compliance of mammography diagnosis and Pathology diagnosis in breast lump, and the detection of microcalcifications, phyllode, and observe the image performance of mammography. Taking infitrating ductal carcinoma (IDC) as an example, the correlation of image performance and clinical pathological features of different types was studied so as to predict if mammography performance was effective in the treatment and prognosis in breast cancer.
  
  
  RESULTS
  Taking Breast Imaging Reporting and Data System (BI-RADS) grade 4A as the critical point, the sensitivity, specificity and accuracy of mammography was 90.80% (109/120), 84.60% (126/149) and 87.40% (235/269); taking BI-RADS grade 4B as the critical point, the sensitivity, specificity and accuracy of mammography was 85.00% (102/120), 93.30% (139/149) and 89.60% (241/269); the correlation analysis suggested that, there was some kind of correlation between the mammography performance and clinical features of breast cancer.
  
  
  CONCLUSIONS
  Mammography is worth being promoted in clinic for its significant clinical value in diagnosing and identifying breast lump.
