It is not normal for axillary lymph nodes to be greater than 2cm in length and diameter. The size of normal lymph nodes should be between 0.5-1.0cm, axillary lymph nodes more than 2cm is not normal, may be caused by inflammatory stimulation. The risk is relatively high, and a timely biopsy is needed to rule out some other malignant lesions in time. If axillary lymphadenitis is diagnosed, anti-inflammatory and antiseptic drugs such as levofloxacin, penicillin and ceftriaxone sodium should be used under the guidance of doctors. If the disease is serious and abscess is formed, timely surgical treatment should be carried out, such as incision and drainage. If the length of axillary lymph nodes is greater than 2cm, we must pay attention to it and actively consult the doctor to exclude the possibility of tumor metastasis and lymphoma. If the lymph nodes are beyond the normal range, you should go to the hospital for examination in time and follow the doctor’s instructions for treatment and use of drugs to avoid spreading and affecting the survival.
