Objectives: To provide demographical and pathological characteristics of breast cancer patients diagnosed in a tertiary clinic with opportunistic screening and diagnostic workup and compare the results with the available national and global breast cancer statistics. Methods: Clinical and pathological data of breast cancer patients diagnosed in our tertiary breast clinic between March 14, 2017 and February 28, 2020 have been entered into a database and analyzed retrospectively. Results were analyzed and compared with the national and global statistics. Results: The total number of patients included in this study were 137 and the number of tumors was 145. Sixty-four (46.7%) patients were detected in screening. All of the patients were female. The mean age was 51.8 years. Eighteen (13.1%) patients were young females (< 40 years), 55 (40.1%) were in 40-49 years, 26 (18.9%) in 50-59 years, 24 (17.5%) in > 60-69 years, 14 (10.2%) in > 70 years. Of the invasive cancers, 100 (79.4%) were invasive ductal, 15 (11.9%) invasive lobular, 6 (4.8%) pleomorphic lobular, 4 (3.2%) papillary, and 1 (0.8%) tubular cancer. Distribution of stages were: 13.1% stage 0, 38.6% stage I, 29.6% stage II, 10.3% stage III, and 8.2% stage IV. The mean tumor diameter was 26.6 mm. Estrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor-2 (HER-2) were positive in 82.5%, 61.9% and 15.8% of the tumors respectively. Conclusions: Results of this study are in accordance with the latest results of the National Breast cancer database, a project governed by the Turkish Federation of Breast Disease Societies (TMHDF), considering the tumor size, age distribution, histologic subtype analysis, receptor status. However, the percentage of earlystage tumors was higher in this study.
