Breast cancer--the diagnostic and therapeutic problem.

The progress made in recent years in the diagnostics of breast cancer, the universal character of mammographic and ultrasonographic screening examinations and the growth of social awareness with respect to this disease have caused a great deal of diagnostic problems. Cases of big, ulcerating cancer tumours, which infiltrate skin have now become history, and are reported sporadically. However, physicians are now facing the problem, which is the diagnosis of 1-5 mm changes detected in examinations. The necessity to diagnose small tumours in combination with 80-90% mammographic sensitivity reported compelled clinical physicists to verify these changes with histopathological examination. In the cases when the clinical examination, the result of a mammographic examination and that of fine needle aspiration biopsy do not provide a coherent picture, a surgeon has to qualify a patient for tumorectomy with an intra-operative study. In the years 1997-2000, 173 breast tumorectomies were made. Patients with benign neoplasm (e.g. adenofibroma, papilloma mammae) or patients with arousing suspicion of oncological anxiety breast tumour were qualified for surgical procedures. Operations were performed in one-day surgery conditions and intra-operative examination was performed in every case. In cases of non-palpable tumours, which were visible in ultrasonography or mammography the changes were marked by an "anchor" in order to be removed and examined histopathologically. The operated patients were 17-89 years old. In the obtained 173 tissue fragments dysplasia benign was recognized in 47.98% of cases, in 42.2% adenofibroma, in 2.31% papilloma mammae, in 1.73% mastitis chronica, in 4.62% ca ductale invasivum and in 1.16% ca ductale in situ has been observed.
