What is the cause of frontal lymph node enlargement

Lymph node enlargement is a common clinical problem. Many reasons may cause lymph node enlargement, and lymph node enlargement can easily occur in various parts of the body. The symptoms and causes of swollen lymph nodes in different parts of the body are different. Swollen frontal lymph nodes are more common and should be taken seriously in treatment. At the same time, the causes of the swelling should also be considered. So what are the causes of swollen frontal lymph nodes?

1. Inflammatory response

Such as acute and chronic lymphadenitis, lymphadenitis tuberculosis. When bacteria enter the body, the lymph nodes will respond by producing more lymphocytes and tissue cells, secreting lymphokines and antibodies to effectively kill the bacteria, which will manifest as swollen lymph nodes. Although lymphadenitis is a minor illness, necrotizing lymphadenitis can sometimes be very serious, with clinical manifestations such as acute onset, high fever, and swollen and painful lymph nodes.

2. Reactive lymph node hyperplasia

Some chronic diseases of the body, such as breast hyperplasia, thyroid nodules, immune system diseases, etc., can stimulate lymphocyte proliferation and cause lymph node enlargement. Other factors that can cause reactive lymph node hyperplasia include viruses, certain chemicals, toxic metabolic products, denatured tissue components, and foreign matter. This situation is often more complicated, and doctors cannot provide more evidence to explain the cause. Even if the lymph nodes are taken for pathological examination, the only conclusion is reactive hyperplasia.

3. Tumor cell lymph node metastasis or lymphoma

The most worrying thing about swollen lymph nodes is a tumor. When malignant tumors occur in various parts of the body, tumor cells often metastasize along the lymphatic vessels and stay in the lymph nodes to divide and proliferate, causing the lymph nodes to swell. The lymphatic system itself can also develop neoplastic changes, such as lymphoma.

4. Note

After lymph node enlargement occurs, it is most important to distinguish the different natures of lymph node enlargement. Professional doctors can roughly judge whether it is benign or malignant based on several aspects, such as the duration of the appearance of the lump, the hardness of the lump, whether there is pain, whether the lump becomes larger and more, and whether there are other discomforts in the whole body. We can also do self-examination. For example, if the lymph nodes are swollen for a short time, feel soft, and are painful or tender, it is generally benign and may be caused by acute or chronic inflammation or other chronic diseases. If swollen lymph nodes do not go away for a long time, are as hard as stone, and are painless or tender, and the number of lymph nodes increases and increases in size over time, you should be alert to the possibility of a tumor.
