OBJECTIVE: To verify the relationship between the body mass index and the development of lymphedema in the postoperative period of breast cancer, its relationship with the type of treatment received and the time elapsed from the surgery. MATERIALS AND METHODS: Medical records of 59 women were collected from May 2008 to February 2009 using data from anamnesis, physical exam; perimetry, estimated volume; reports, symptoms, and notes in medical records. The analysis was performed using means and standard deviations for the quantitative and qualitative variables (absolute and relative) and to verify the risk factors used, the Student's t-test and Pearson's chi-square test with a 5% significance level (0.05). RESULTS: The frequency of lymphedema was 47.5%, with 40.7% being obese. There was a significant difference between the groups of lymphedema and BMI (p=0.002). There is also a significant difference between lymphedema in the group without axillary radiotherapy (p=0.003) and an association between post-surgical time and lymphedema (p=0.006), being greater after six months of surgery. CONCLUSION: There is a correlation between obesity and the development of lymphedema. The types of treatment do not seem to have influenced their development, and the longer the surgery has elapsed, the greater the risk of their appearance.
