Tumour Size Distribution of Invasive Breast Cancer in a One-Year Period: Case Study Herzegovina

To analyse the early stage breast cancer tumour size distribution as an important prognostic factor among the female patients within our local geographic region of Herzegovina. This cross-sectional retrospective study included 379 patients who were treated in 2017 at the Oncology Clinic, University Clinical Hospital Mostar. The patients were divided into two groups based on their primary tumour size: early (≤2 cm) and late (>2 cm) stage groups. The number of patients tested for advanced stage tumours surpassing 2 cm was statistically higher (χ =106,325; p2 cm but ≤5 cm in greatest dimension (T2). The patients' knowledge about breast cancer, availability and adherence of mammography did not show any statistically significant difference with regard to tumour size, while the number of patients with smaller tumours who indicated that they underwent regular mammography was statistically significantly higher (χ =13,629; p
