title: [Comparing two diagnostic methods used for breast neoplasm in a cancer centre in Colima, Mexico].
abstract: OBJECTIVE
  Determining the relationship between mammography neoplasm reports and histopathological diagnosis of neoplasms.
  
  
  METHODS
  A descriptive cross-sectional study was carried out. Patients were included who were attending the state cancerology centre (Centro Estatal de Cancerología) in Colima, Mexico. Inclusion parameters were: females having mammography and BIRADS score of 1 or over; females having biopsy and histopathology diagnosis; females of all ages, all clinic stages having a complete clinic record. Frequency, percentages, means and standard deviations were applied for descriptive statistics. Student's t-test, the Chi square test, OR and 95 %CI were applied for inferential statistics. Differences were considered to be significant when p<0.05.
  
  
  RESULTS
  No relationship between a BIRADS score classified as being benign (BIRADS I-II-III) or malign (BIRADS IV-V) was found with histopathological results (benign or malign) (p=0.0666). Significant relationships by category were found in a separate analysis: category IV (OR=0.024, 95 %CI=0.005-0.11, p=0.0007) and category V (OR=40.5, 95 %CI=9.03-181.3, p=0.0002).
  
  
  CONCLUSIONS
  I, III and V BIRADS scores had a relationship with histopathological diagnosis, while category II and IV BIRADS scores had no relationship. However, only categories 4 and5 were statistically significant.
