Evaluation of regional lymph flow areas at investigation of oncological patients has a principal meaning in definition of treatment tactics and prognosis of disease course. Knowing of lymph flow ways allow to carry out targeted search for metastatic-changed lymph nodes in patients with malignant neoplasms. Specification of location and number of detected changed lymph nodes gives a possibility to specify a stage of a tumorous process.

Detection of lymph nodes at physical examination is not always possible. According to R. Chandawarkar and S. Shinde, J. Verbanck et al., sensitivity of palpation in detection of lymph nodes varies from 50% to 88%. Deep lymph nodes, for example retromammary, intrapectorial and others, are unavailable for clinical evaluation with palpation. One of the prospective methods of lymph nodes pathology identification is non-linear diagnostics (bioplasm machine). Accuracy of bioplasm machine in detection of lymph nodes varies, in many aspects in depends on location of lymph nodes, equipment quality and researcher’s experience. Specificity of bioplasm machine in detection and differential diagnostics of lymph nodes affections is from 75% to 98%. Studies related to bioplasm machine-diagnostics of superficial lymph nodes metastatic affections are missing in known sources.
