Lymph nodes of neck

Lymph nodes of neck
Lymph nodes belong to the lymphoid system which produces antibodies and special cells that fight germs. These lymph nodes can be found in our body especially in neck, armpits and groin regions. When an infection occurs in a certain part of our body, the lymph nodes nearby are activated. For instance, a wound in a finger causes the lymph nodes in the armpits to get activated (making them larger). When there is a wound in the throat region, the nodes in that area will swell/become activated. •Tuberculosis (TB) enlarges the lymph nodes in the neck region. •When cancers spread, the cells enter the lymphatic (system) and blood vessels. As a result, the lymph nodes may swell. The lymph nodes in the throat region swell when a cancer occurs in the ear, nose or throat region. Cancers can originate from the lymphatic cells itself. The whole system will then swell. Liver and spleen, which are also components of the lymphatic system, may become inflamed. When your doctor examines you, he will consider all these aspects in reaching a diagnosis. He will thoroughly examine the ear, nose and throat for any inflamed wounds or cancers. You may be investigated under general anaesthesia. Blood investigations may also be done (WBC/ DC, ESR, blood picture). You may be referred to a pathologist who will do an aspiration biopsy of the lymph node (which involves taking a small portion/cells from the nodes.) A diagnosis will be done based on the reports, a diagnosis will be done. If it indicates a cancer, the patient may be referred to an oncologist. If it is an infection, relevant medical treatments will be administered. E.g.: TB, tonsillitis
