Can biopsy needle cause tumor metastasis in fine needle biopsy operation?

At present, the development rate of breast tumors in China is gradually increasing. Many treatment methods are facing the problem of determining the nature of clinical disease. Although there are many examination methods, such as hand diagnosis, LCD, infrared breast scan and its image analysis system, FLATSE mammography and so on. However, the conclusion of such tests is still a clinical diagnosis, and their allowable error rate is still high, which is not suitable for the current advanced level of breast cancer treatment.

In order to better and faster treat the disease, it is necessary to obtain information about the nature of the disease, that is, a type of diagnosis, including cytology and pathological examination, cytology is the use of fine needle sampling in the mass, smear, analysis of cellular components, DNA content determination, cell culture analysis and other means to determine the nature of the clinical mass. Pathological biopsy is through a complete resection surgery lumps or bumps considerable part, on the one hand as a treatment role, such as mammary gland fibroma, cyst by biopsy, surgery and cure can understand mass properties on the other hand, by cells of the pathological understanding mass composition, structure and level, determine the nature of the tumor, diagnosis, treatment in a timely manner. In general, the accuracy of cytology and pathology is 93% and 99%, while the accuracy of common clinical diagnosis is less than 90%. However, in clinical practice, the author often encountered the fear of needle aspiration biopsy, surgical biopsy will cause metastasis and refuse such examination, and even some patients will lose the opportunity of treatment, resulting in uncontrollable disease. The author reviewed a large number of literatures and found no reports of tumor metastasis and disease progression caused by such examination.
