Normal lymph nodes are 0.2cm to 0.5cm in diameter, and when the diameter exceeds 1cm, the lymph nodes are slightly enlarged. Common causes include lymphadenitis, lymph node tuberculosis and malignant tumor.
1. Lymphadenitis: including acute lymphadenitis and chronic lymphadenitis, usually caused by bacteria or viruses and other pathogenic microorganisms, manifested as slightly enlarged lymph nodes in the neck and clavicular region, pain, good mobility, no adhesion with the surrounding tissues, and lymph nodes can be shrunk through anti-inflammatory and antiviral treatments.
2. Lymph node tuberculosis: tuberculosis can spread to lymph nodes and lead to multiple slightly enlarged lymph nodes all over the body, which is characterized by hard texture and mutual adhesion, often accompanied by systemic symptoms such as low-grade fever, night sweating, malaise, and decreased appetite, etc., and requires early, combined, standardized, appropriate amount, and whole course of anti-tuberculosis treatment.
3. Due to malignant tumors: malignant tumors in lungs, stomach, liver, etc. metastasized to lymph nodes or malignant tumors in lymph nodes, such as lymphoma, etc. can lead to slightly enlarged lymph nodes, which are characterized by hardness, absence of pressure and pain, adherence to the surrounding tissues, and not easy to be pushed, etc., and anti-tumor treatments are often needed.
When you find slightly enlarged lymph nodes, you should consult a doctor in time to clarify the cause of enlarged lymph nodes, so as to treat the cause of the disease.
