Breast lymph nodes are considered to be the phenomenon of enlarged lymph nodes in the breast. Since lymph nodes are the body’s immune organs, located in all parts of the body and connected to each other through the lymphatic network, they are not visible under normal circumstances. When inflammation or lymph node infection occurs in the breast, the lymph nodes will be enlarged, and then ultrasound examination can find the enlarged lymph nodes. The lymph nodes will shrink or even disappear when the inflammation dissipates through oral antibiotic treatment, so there is no need to worry too much. Enlarged lymph nodes may also be caused by lymphoma, which is a malignant tumor in the lymphatic system, with multiple enlarged lymph nodes as the early manifestation, you can do ultrasound examination or take lymph node biopsy after consultation. Cancer cells have metastasized and planted in the lymph nodes, resulting in enlarged lymph nodes. Try to go to the hospital to check the specific cause and then treat the symptoms.
