چکیده
The problem domain Breast cancer is the commonest cancer (excluding skin cancer) which affects women in North America, Europe and the Antipodes.(1) The prognosis for breast cancer is primarily dependent on how far the tumour has spread before treatment is instituted and this is a relatively direct function of time. If the diagnosis of breast cancer can be made earlier then the prognosis is improved since more cases will have disease localised to the breast, without spread to lymph nodes in the axilla or more distant sites. A number of countries, including the UK and USA, have instigated screening programmes for breast cancer which use radiographs of the breast (mammograms) as the screening modality. Mammographic abnormalities which raise the suspicion of malignancy include microcalcification and parenchymal deformity but these are not entirely specific and a confirmatory method of diagnosis is required before definitive therapy can be instituted.(2) The most common confirmatory method is fine needle aspiration of the breast lesion (FNAB) and cytological examination.(3) In this method cells from the breast lesions are sucked into a syringe through a fine bore needle (similar to that used for taking blood samples) and are then transferred to a transport solution and sent to a pathology laboratory. In the laboratory the fluid is spun down in a cytocentrifuge to produce a deposit of cells on a glass slide.(4) This slide is stained, usually using the Papanicolaou or Giemsa methods, and is then viewed down the microscope by a trained cytopathologist.

Concordance Rate between Fine Needle Aspiration Biopsy and Core Needle Biopsy in Breast Lesions
Background and Objectives:Breast cancer is the most common cancer among women worldwide. Fine needle aspiration biopsy (FNAB) is one of the methods of breast biopsy which is fast, easy and cost effective. The aim of this study was to evaluate the concordance rate between pathologic results of sonography or stereotaxy guided FNAB and guided core needle biopsy (CNB) in the evaluation of breast le...

HSP27 diagnostic utility in the fine needle aspirate of breast. Correlation with progesterone and estrogen receptors.
Fine needle aspiration (FNA) is routine diagnostic tool in breast tumors assessment. In some cases, however, limitations of this method do not permit an unequivocal diagnosis. In these, suspected, cases immunocytochemical evaluation of selected biological markers may be of help. The aim of the study was assessment of HSP27 value in diagnosis and discrimination of benign and malignant breast les...
متن کاملThree years of experience with routine use of telepathology in assessment of excisional and aspirate biopsies of breast lesions.
AIM To examine the applicability of routine telepathology to accurately diagnose breast lesions. METHODS During a 36 month period, a dynamic telepathology system was used to assess 315 excisional biopsies and 209 fine needle aspirates of breast lesions submitted by surgeons located 20 km from the hospital. The results of the gross and microscopic telepathology diagnoses were compared with fin...
متن کاملFine Needle Aspiration Cytology of the Breast: The Nonmalignant Categories
Currently, accurate diagnosis of breast lesions depends on a triple assessment approach comprising clinical, imaging and pathologic examinations. Fine needle aspiration cytology (FNAC) is widely adopted for the pathologic assessment because of its accurracy and ease of use. While much has been written about the atypical and maliganant categories of FNAC diagnosis, little covers the non-malignan...
