| infectious agents | Bacterial/viral infections (such as strep throat, Epstein-Barr virus) | high | Local redness, swelling, heat and pain |
| immune diseases | Systemic lupus erythematosus, rheumatoid arthritis | in | Swelling in multiple locations with joint symptoms |

| reactive hyperplasia | Post-vaccination, drug reactions | low | temporary mild swelling |
2. Analysis of recent hot-related events
According to data monitoring across the entire network, discussions about lymph nodes in the past 10 days have mainly focused on the following aspects:

3. Danger signs to be alert to
Based on the recent popular science content of medical experts, the following characteristics of lymph node enlargement require prompt medical treatment:
| Hazard characteristics | possible prompt | Recommended to check |
|---|---|---|
| Diameter＞2cm | Pathological changes | Ultrasound examination |
| Hard texture | Tumor may | needle biopsy |
| progressive increase | malignant lesions | CT/MRI |
| Night sweats accompanied by fever | systemic disease | blood test |
4. Scientific response suggestions
1.Observation period management:For mildly enlarged lymph nodes (<1cm), it is recommended to observe them for 2-4 weeks and record the size changes.

4.Psychological adjustment:Recently, psychological experts pointed out that about 60% of lymph node enlargement is a benign reaction, so there is no need to be overly anxious.
5. Recent related research progress
According to the latest literature report (November 2023):
| research institute | Discover content | clinical significance |
|---|---|---|
| Johns Hopkins University | Discover markers of changes in lymph node microenvironment | Early identification of benign and malignant |
| Peking Union Medical College Hospital | Establishing reference values for lymph node size in Chinese people | More accurate diagnostic criteria |
Conclusion:Swollen lymph nodes are an important signal from the body that can be a defense response to a common infection or a sign of a serious illness. Recent online discussions reflect increased public health awareness, but there is also information confusion.
