The status of axillary lymph node (ALN) is an important reference indicator for breast cancer surgery and systemic treatment, which is also an important prognostic indicator for breast cancer. Therefore, it is extremely important for surgeons to accurately determine whether axillary lymph nodes have metastasis and the number of metastatic lymph nodes. The value of ultrasound diagnosing the status of axillary lymph nodes was controversial in recent publications. Therefore, there is a high need to prove the accuracy and precision of ultrasound for axillary lymph node metastasis in breast cancer patients. The aim of this study is to assess the usefulness of ultrasound in the diagnosis of axillary lymph node status in breast cancer patients by gathering in vivo and vitro ultrasonographic parameters to build a clinical useful categorization system
