The appearance of lymph nodes like broad beans is generally only about 3mm, and general inflammation and tumor metastasis can stimulate lymph node enlargement. If painless progressive enlargement is dangerous, we should consider the possibility of tumor, go to the hospital for surgery, find out the reason and prevent the delay of the disease.

When the human body has inflammation, disease and infection, the lymph nodes will swell. Usually these swollen lymph nodes have tenderness. I'll be fine when I get better. But if the lymph nodes are swollen for a long time, it is best to check them.

Extended data:

Lymph nodes are mainly composed of lymphoid tissues and lymphoid sinuses, and the outer bread is covered by dense connective tissue, which extends into the lymph nodes to form many gaps or trabeculae, forming a reticular lymph node scaffold and dividing the lymph nodes into many parts. The part near the periphery of lymph nodes is called cortex, which contains some lumps of lymphocytes, called lymph nodes.

Cell division and proliferation often occur in the center of nodules, so it is called germinal center. The central part of lymph nodes is called medulla, which is mainly composed of cord medulla composed of lymphoid tissue. In lymph nodes, all the channels through which lymph passes are called lymphatic sinuses.
