Introduction: Breast cancer is the most common cancer in women and the first cause of cancer death in women. This tumor often has hormonal receptors. The absence of these hormonal receptors leads to inability to treat the normal hormonal methods correctly.
Objectives: In the present study, frequency of triple negative breast cancer in referrals patients to all patients with breast cancer involvement was investigated.
Patients and Methods: This cross-sectional study was performed on patients with breast cancer. Accordingly, all patients with breast cancer involvement who referred to Firoozgar hospital from 2016 Until 2019 were evaluated sensually. The extracted parameters included the age, the status of the hormonal receptors in terms of positive or negative, and the degree of tumor based on the pathology in the case.
Results: In this study, 1840 patients were diagnosed with malignancies, of which 266 (14.5%) were infected with a variety of breast malignancies negative triple breast was 48 patients (20.6%). Mean and standard deviation of patients with triple negative malignancy were 47.63 ± 13.34 years. We also observed the stage of breast cancer, the second most common stage (23 patients and 47.9%), and the first stage with the lowest incidence (4 patients and 8.3%) among patients.
Conclusion: Considering the increased use of chemotherapy in treating this type of malignancy and the high cost of treatment in these patients, this malignancy should be considered in order to identify the disease early in order to plan for proper health and reduce the cost of the treatment.
