title: [Does renal transplantation increase the risk of breast diseases?].
abstract: OBJECTIVE
  To evaluate the risk of breast pathology occurrence in a group of kidney transplanted patients.
  
  
  METHODS
  and methods. In the last five years, 30 kidney-transplanted women underwent systematic breast evaluation in our institution and were included in this retrospective study (exposed-group). To compare with this exposed-group, 90 non transplanted women undergoing breast evaluation in the same period at our institution (non-exposed group), were retrospectively randomized. In both groups, results of breast evaluation were classified in two categories (normal and abnormal) and distribution of benign and malignant breast pathologies were evaluated. The mean exposition-time was determined in months in the exposed-group. Comparative analysis of both groups included a comparison of mean patients age and evaluation of the relative risk (RR) of breast pathology occurrence.
  
  
  RESULTS
  Mean exposition time was 72.7+/-66.6 months. The percentages of benign breast pathology were 93.7% in the exposed-group and 83.3% in the non-exposed group. Percentages of cancer were respectively 6.3 and 16.7%. Mean patient age was quite similar in the exposed-group (50.7+/-10 years) and in the non-exposed group (50.6+/-10.5 years). The relative risk of breast pathology occurrence was 1.70 (0.99<RR<2.91) and was not significant.
  
  
  CONCLUSIONS
  In this retrospective series, no risk of breast pathology occurrence was demonstrated in a population of kidney-transplanted patients.
