  • Introduction: Introduction: Breast Cancer is a type of cancer that arises in the breast organ. Cancer happens when breast tissue cells continue to grow abnormally. Breast cancer rates are rising in developing Asian countries, especially Iran. Diagnosis of breast cancer in the early stages is one of the most essential issues in preventing the development of breast cancer.
  • Methods: Material and Method: Information on height, weight, stage of breast cancer, and body mass index at the time of diagnosis is available for 109 women undergoing early-stage breast cancer treatment in Nemazee hospital between the years 2017 to 2019. We examine the relationship of BMI to stage at diagnosis with t-tests.
  • Results: Results: Patients with a body mass index of 27kg/m2 or more have stages 3 and 4 of breast cancer, while patients with BMI below 27kg/m2 have stages 1 and 2 of breast cancer. Our result showed that a high body mass index is associated with stages 3 and 4 of breast cancer at diagnosis(P≥0.05).
  • Conclusion: Conclusion: High BMI and obesity are prognostic factors for the breast cancer and death of the patient. Early diagnosis of breast cancer is essential for the prevention and breast cancer treatment management.
