Overweight is considered a risk factor for breast cancer. The effects of increased body mass index (BMI) and breast diseases among postmenopausal women have been explored in a limited amount of studies.

The objective of the current research is to investigate the association of over the average BMI with breast cancer in a multiethnic minority cohort.

This study is based on 60 individual breast cancer cases and 120 controls from the Department of Thoracic Surgery in Military Medical Academy – Sofia (MMA), aged 50-70 years in 2012-2013. Data regarding BMI and clinical factors were obtained by medical records. Data were assessed using Fisher Exact Probability Test with the Freeman –Halton 2x3 extension and the result is p=0,3105.

Women with breast cancer happen to be more likely overweight with an average BMI over 25, while women without breast cancer have BMI that equals 25 or is less. There was not a significant relationship between increased BMI and breast cancer among postmenopausal women (p>0.005), but it has its importance considering the small sample size.

The patients that have been used in the research have been broke into 4 groups:

  1. Underweight with BMI < 18,5 kg/m2.
  2. Average with BMI from 18,5 to 24,9 kg/m2.
  3. Overweight with BMI from 25 to 29,9 kg/m2.
  4. Obese with BMI > 30 kg/m2

The study comes to the conclusion that overweight is a risk factor
