Enlarged lymph nodes on both sides of the neck in women may be caused by microbial infections, tuberculosis and tumor diseases. 1. Bacterial or viral microbial infections, such as oral infections, respiratory infections, skin infections, etc., will stimulate the proliferation of lymphocytes, thus strengthening the body’s ability to resist infections, which can be manifested as enlarged lymph nodes in the neck. Bacterial culture and drug sensitivity test should be carried out in time, and appropriate antibiotics and antiviral drugs should be used for treatment. 2. Tuberculosis caused by Mycobacterium tuberculosis infection will lead to enlarged lymph nodes in the neck, which should be treated with anti-tuberculosis drugs such as isoniazid and rifampicin. The principles of early, combined, moderate, regular, and complete medication should be observed. 3. Tumor diseases, such as breast cancer in women, may have metastasis in the neck, infiltrate lymphocytes and divide and proliferate in them, resulting in enlarged lymph nodes in the neck. Pathological biopsy should be performed in time to clarify the nature of the disease, and surgical resection with radiotherapy should be performed. It should be noted that when the swelling of the lymph nodes in the neck is found, it is necessary to go to the hospital in time for examination and treatment under the guidance of the doctor.
