title: [Associated factors of lymphedema in breast cancer patients].
abstract: OBJECTIVE
  to determine the prevalence of lymphedema and its associated factors in breast cancer patients.
  
  
  METHODS
  Two hundred and fifty women that had undergone more than six months of breast cancer treatment and were being treated at an oncology reference hospital in Juiz de Fora, Minas Gerais, Brazil. They were interviewed and submitted to physical evaluation. Data from the patients' medical records regarding the treatment of breast cancer, the extent of axillary intervention and the tumor were analyzed. Lymphedema was diagnosed when the difference between both upper limbs was 2 cm or more by perimetry. The groups of women with and without lymphedema were compared regarding the possible risk factors, and central tendency, dispersion, and prevalence were measured, with a significance level of 95%.
  
  
  RESULTS
  One hundred and twelve women (44.8%) presented lymphedema. A significant difference was found between the groups of women with and without lymphedema regarding the median numbers of removed lymph nodes (p=0.02); presentation of superficial lymphatic thrombosis in the arm ipsilateral to the surgery (p<0.01); local application of radiotherapy, use of chemotherapy (p<0.01 for both); removal of the cuticles of the ipsilateral hand with pliers, and weightlifting after the treatment (p<0.01 and p=0.05, respectively).
  
  
  CONCLUSIONS
  the association between lymphedema and the mentioned factors requires an interdisciplinary approach to this condition. It is of paramount importance that health teams and patients become aware of the prevention and treatment of lymphedema, a condition often undervalued.
