In the past, most patient of breast cancer suffered side effects due to the useless removement of Axillary Lymph Node, but there is no need to remove it because of the result in this study. The purpose of this study is to save surgery time and side effects after surgical operation for patients with breast cancer by making decisions of operation range for metastasis in first Stenosis Lymph Node using the $^{99m}Tc-Tincolloid$ Scintigraphy and the Micro Probe for radioisotope. As a result of this study, 15 among 20 patients became objects of this study could reduced side effects for operation because there were no axillary lymph node operations. However there is no standard for method of this treatment. It should be standardize where inject point is, how much $^{99m}Tc-Tincolloid$ should be injected(radioactivity value), and the need of massage and Lymph Scintigraphy. Nevertheless I think that this result of study is useful to reduce suffering and side effects from breast cancer and also we should try to do that continuously. The objects for this study were 20 patients diagnosed as breast cancer by Ultrasonography, Mammography & Biopsy. The average of patient age was 45.4 years and its range was between 31 and 71 years. In case of clinical period there were 9 patients of Period I and II patients of Period III. The equipment for this study were $^{99m}Tc-Tincolloid$ describing the Stenosis Lymph Node as a tracer, Micro Probe : Neoprobe 2000(the rest is Gamma Probe) tracing the location, and MS-II Gamma Camera : SIEMENS(the rest is MS-II Gamma Camera) describing the images. There were 3 methods for this study, after selecting one of those methods all 20 patients were performed Stenosis Lymph Node diagnosis & Gamma Probe in operation room. The result was that I imaged all the 20 patients, and seek the Stenosis Lymph Node by using Gamma Probe. Metastasis in Stenosis Lymph Node was 5 and Metastasis in Axillary Lymph Node was 3 between Metastasis in Stenosis Lymph Node cases. Finally 15 patients were also proved that Axillary Lymph Node was Positive and that means there was no Metastasis in Axillary Lymph Node.
