Lumps in the armpits are usually enlarged lymph nodes. If they are caused by local inflammation and infection, such as mastitis or inflammation of the upper limbs on the affected side, anti-inflammatory treatment should be carried out actively, and broad-spectrum antibiotics can be applied or intravenous antibiotics can be used to treat the lymph node enlargement, and the lymph node enlargement will disappear on its own after the inflammation has subsided. If it is caused by systemic lesions, such as breast cancer, lymphoma, etc., according to the specific conditions of the patient, surgery and chemotherapy should be used for treatment. In addition, armpit lumps may also be skin diseases, such as lipoma, sebaceous cysts, etc. If the patient has no conscious symptoms, and the size of the lumps is small, and has no impact on life and work, it can be temporarily observed without treatment, if the size of the lumps grows faster, it can be removed through surgery.
