Transactions of the breast biopsy
Imaging guided percutaneous needle biopsies:
1. Fine-needle aspiration biopsy (FNAB): FNAB cheap, practical, less complications, a method of high specificity and sensitivity. Diagnostic accuracy and evaluating the quality of the sampling rate varies between 50-95% according to experience. Pregnant and nursing women also reported to be successful.
2. Cyst aspiration for diagnosis and treatment.
3. Core biopsy: small pieces of breast tissue lesions and their histological examination of tissue samples taken. Mammography and U.S. guidance can be made. Failure rate was lower than histological diagnosis. Large-scale automated core breast biopsies have been reported successful applications. However, core biopsies applications has been noticed that some of the limitations. Done a lot of sampling, repeated blood samples decreased by increase in breast tissue specimens is not eliminated. In addition, calcified lesions, the diagnostic failure in cases of atypical ductal hyperplasia and DCIS can be seen.
4. Vacuum-assisted biopsies (BDD): increasing frequency in the diagnosis of suspicious breast lesions, biopsy is a new system. Larger than other systems with BDD percutaneous biopsy tissue samples are obtained and the lesions sometimes can be removed completely. Tri-cut biopsy technique through a single login to take more than the parts, histological diagnosis, the rate of failure is low, without causing a cosmetic defect, such as features of benign lesions can be removed completely or nearly completely, given BDD can be argued that excisional biopsy may be a good alternative. Percutaneous biopsy has some advantages over surgical biopsies: A cheaper and easier implementation, less than the complications of a biopsy, removal, and scar tissue that may interfere with routine follow-up evaluation include mamography. Percutaneous biopsies of patients benefiting the most to maximize the delay in diagnosis or follow-up patient compliance is very important to avoid the passage of malignancies. Although the reliability of diagnostic follow-up biopsies to determine the false negative results is also important to overkill extends
