What causes swollen lymph nodes under the armpit before menstruation?

Lymph nodes are an important part of the body's immune system. When a person's body is infected with bacteria or has inflammation, abnormalities may occur in the person's lymph nodes. If you get a sore throat after eating chili peppers, your lymph nodes will swell and feel painful when pressed. This can happen at any age, so we must pay attention to swollen lymph nodes and not take it lightly. Some women experience swollen axillary lymph nodes before menstruation. What is going on?

The phenomenon of lymph nodes increasing in size due to internal cell proliferation or tumor cell infiltration. Common clinical signs. It can be found by touching the submandibular, neck, supraclavicular fossa, axilla and groin areas, but enlarged lymph nodes in the body such as the hilum of the lung, mediastinum, retroperitoneum and mesentery can only be found by X-ray, CT and B-ultrasound.

There are three common situations in which lymph nodes are swollen:

① Benign swelling. Includes swelling caused by various infections, connective tissue diseases and allergic reactions. The clinical course is usually benign and can be fully recovered within a certain period of time as the cause is eliminated.

② Malignant swelling. It includes malignant tumors originating in the lymph nodes, such as lymphoma, lymphocytic leukemia and malignant histiocytosis, as well as lymph node metastasis of other malignant tumors, such as lung cancer, gastric cancer and breast cancer. The clinical course is malignant, with persistent and progressive enlargement of lymph nodes. If not treated actively, the disease will often progressively worsen and lead to death.

③Swelling between benign and malignant. Such as angioprimitive immunocytic lymphadenopathy and angiofollicular lymphadenopathy. It often starts out benign but can become malignant and fatal. Therefore, after confirming that the lymph nodes are swollen, the key is to determine their cause and nature. Local swelling accompanied by obvious pain often indicates infection, while progressive painless swelling often indicates malignant tumor disease. Bone marrow aspiration and especially lymph node biopsy can help confirm the diagnosis. The treatment of swollen lymph nodes depends on the cause. For example, streptomycin and remifentanil can be used for lymph node tuberculosis. If it is malignant lymphoma, combined chemotherapy should be the main treatment. If it is late-stage cancer metastasis, the prognosis is extremely poor.
