Analysis of Key Radiographic Characteristics of Early Invasive Breast Cancer, Stages T₁ₐ₋bN₀M₀ and DCIS

Relevance : The systematization of radiological signs microcarcinomas will increase the frequency detection disease at an early stage and maximize effectiveness breast cancer treatment. Purpose To assess key characteristics forms (invasive tumors up to 1.0 cm ductal carcinoma in situ). Material methods were studied 110 patients with verified cancer: situ (DCIS), invasive 1 size according morphological examination surgical material absence regional distant metastasis — p T₁ₐ₋ b N₀M₀. Results main detected mammography (MG) nodular mass without microcalcifications 26 cases (23.9 %), nodule 35 (32.1 27 (24.8 %) a tumor node. In addition, 17 (15.6 there was violation architectonics or focal asymmetry, 4 (3.7 no malignant process revealed all MG. changes most (83 cases, 76.1 interpreted as BIRADS 5, which indicates extremely high probability presence neoplasm. 9 (8.3 after mammography, diagnosis 4, 16 (14.7 category 0 assigned, required additional methods, only patient (0.9 benign. Conclusions Mammography performed 92 (84.4 based on assessment signs, establish 4/5 category, served basis for performing biopsy verifying diagnosis. However, 15 % diagnostic difficulties interpreting data, confirms data world literature complexity differential microcarcinomas.
