Introduction

Causes of lymphadenopathy include benign enlargement, malignant enlargement, and conditions intermediate between benign and malignant. Major causes include angiofollicular lymph node hyperplasia and angioimmunoblastic lymph node lesions. After detecting lymph node swelling, it is important to determine the underlying cause and nature. Localized swelling with significant pain is often due to infection. If lymph node enlargement is found, prompt medical evaluation and treatment are necessary.

Causes of lymphadenopathy include benign enlargement, malignant enlargement, and conditions intermediate between benign and malignant.

1. Benign enlargement

This includes various infections, connective tissue diseases, and allergic disorders. These are generally benign, and full recovery can usually be achieved within a period of time once the underlying cause is eliminated.

2. Malignant enlargement

Primary malignant tumors of lymph nodes include lymphoma, lymphocytic leukemia, and malignant histiocytosis, as well as metastatic cancers such as lung cancer, gastric cancer, and breast cancer. These present clinically as malignant conditions, with progressive lymph node involvement requiring prompt treatment.

3. Enlargement intermediate between benign and malignant

Mainly includes angiofollicular lymph node hyperplasia (Castleman disease) and angioimmunoblastic lymphadenopathy. After detecting lymph node enlargement, it's essential to determine the cause and nature. Localized swelling with obvious pain is often due to infection, whereas progressive painless enlargement typically indicates a malignant process. Diagnosis can be established through comprehensive evaluation including physical examination, color Doppler ultrasound, imaging, fine-needle aspiration, biopsy, clinical symptoms, and laboratory tests.

In addition, lymphoid hyperplastic disorders should also be considered. If lymphadenopathy is detected, timely medical evaluation and treatment are necessary.

Causes of enlarged axillary lymph nodes in women

Enlarged axillary lymph nodes in women are associated with breast-related diseases, such as mastitis or breast tumors, and may also be caused by lymphoma. Patients with mastitis often present obvious systemic symptoms, such as chills, high fever, and increased pulse rate, which can lead to reactive hyperplasia and enlargement of the axillary lymph nodes. In addition, tuberculous lymphadenitis can also cause enlarged axillary lymph nodes in women.

Are multiple lymph nodes in the neck serious?

The severity of multiple cervical lymph nodes is generally related to the underlying cause, such as chronic lymphadenopathy, inflammation, or tumors.
