Lymph is the largest immune organ in the human body. If there is any problem with the lymph, it will pose a great threat to the health of the body. This is something everyone should know. If you don’t know what to do if you have lymph nodes on your neck, you should go to a regular hospital for timely treatment.

Lymph (Latin: lympha), also called lymph fluid, is a colorless and transparent liquid in the human and animal bodies. It contains lymphocytes and is formed when tissue fluid infiltrates into the lymphatic vessels. Lymphatic vessels are tubes similar in structure to veins and are distributed throughout the body. Lymph circulates in the lymphatic vessels and finally flows into the veins, serving as the medium for tissue fluid to flow into the blood. Lymph exists in various parts of the human body and plays a vital role in the human immune system.

The upper cervical lymph nodes are mostly local lymph nodes of the head lymphatic vessels, arranged along the junction of the head and neck, located superficially, and divided into 5 groups. One is the occipital lymph node, one is the mastoid lymph node, one is the parotid lymph node, and one is the submandibular lymph node, which is located near the submandibular gland and collects lymph from the eyes, nose, lips, teeth, tongue and floor of mouth, and injects into the upper and lower deep lymph nodes on the outside of the neck. One is the submental lymph node, which is located in the submental triangle and collects lymph from the chin, floor of mouth and tip of tongue, and injects into the submandibular lymph node and the digastric lymph node of the internal jugular vein.

Common causes include:

(1) Inflammation Acute cases are characterized by redness, pain, and heat, with rapid onset and local tenderness. The swelling will subside after anti-inflammatory treatment. Chronic cases have a long course of disease, are active, non-tender, and are often located in the submandibular area.

(2) Tuberculosis. It can be primary or secondary to tuberculosis lesions in the abdominal cavity. The course of the disease is long. The enlarged lymph nodes are in the form of strings, with medium texture, movable, and no tenderness. They can adhere to each other into clumps. If caseous necrosis occurs, fistulas will form if they rupture.

(3) Metastatic malignant tumors. It is one of the causes of cervical lymphadenopathy. The primary lesions are mostly located in the head and neck. The lumps gradually increase in size, become hard, have poor mobility, and are not tender. They are often unilateral but may also affect both sides. Nasopharyngeal cancer, tonsil cancer, and laryngeal cancer often metastasize to the supraclavicular lymph nodes. Cancers of the nose, paranasal sinuses, mouth, and face often invade the submandibular lymph nodes, and esophageal cancer metastasizes to the supraclavicular lymph nodes.

(4) Malignant lymphoma. It is a malignant tumor that occurs in the lymphoreticular tissue. The tumors of non-Hodgkin's lymphoma are painless, progressively enlarged, hard, and have poor mobility. Hodgkin's lymphoma is often bilateral, with symptoms such as fever, hepatosplenomegaly, weight loss and fatigue.

(5) AIDS. It is caused by invasion of human immunodeficiency virus. The disease has a long course, with gradual enlargement of lymph nodes, often with enlarged inguinal lymph nodes, fever, weight loss, fatigue and leukopenia.

The above introduces some reasons why lymph nodes grow on the neck. I hope that after reading the above reasons, you will know how to prevent such a situation. If there is a problem with the lymph nodes, it must be treated in time, otherwise it will lead to a series of problems and diseases in the body. Everyone should take good care of their bodies and develop good living habits.
