Lymph nodes are small bean-shaped organs found throughout the body and linked by lymphatic channels. Lymph nodes are an important part of the immune system and act as “filters” which can trap foreign particles and cancer cells.
In their normal state, they are usually smaller than a pea in size, but in certain conditions, such as infections and cancers, they may become enlarged. When the lymph nodes in your neck are enlarged, you may be able to feel them as round to oval shaped swellings in your neck.
