Axillary lymph nodes can be distinguished from benign and malignant by the size and shape of the lymph nodes, whether the edges are clear, and whether there is nodal calcification.
1. Benign lymph nodes: under color ultrasound, benign axillary lymph nodes have uniform size and morphology, obvious and clear borders, uniform internal echoes, clear structure, no calcification inside the lymph nodes, and no abnormal blood flow around the lymph nodes. There is no obvious pain, the lymph nodes are not fused and can be moved by touch.
2. Malignant lymph nodes: ultrasound can observe that the size of malignant axillary lymph nodes increases, the internal echogenicity is not uniform, may be accompanied by calcification, the cortex and medulla are not clearly demarcated, the lymphatic portal structure disappears, and there are abnormal blood flow signals around the lymph nodes. It may be accompanied by pain, fusion of lymph nodes, adhesion with surrounding tissues, and difficult to move by touch.
If you find axillary lymph node enlargement should be taken seriously, it is recommended to go to the hospital in time to clarify the cause to avoid adverse consequences.
