Posterior cervical lymph nodes are part of the lymphatic system and located just above the base of the neck.
Lymph fluid can collect cancer cells and transport them throughout the lymphatic vessels to the lymph nodes. When posterior cervical lymph nodes are swollen without signs of infection present, it may be a sign of cancer.
The posterior cervical lymph nodes are located along the sides of neck and drain lymphatic fluid from both the head and neck.
Located in a line running vertically along the back edge of the neck, the posterior cervical lymph nodes are positioned just above the base of the neck.
When the head is suffering from an infection, the lymph nodes in the head and neck will filter out and destroy the infection-causing bacteria. The lymph fluid can also collect cancer cells and transport them throughout the lymphatic vessels to the lymph nodes. Another problem with the lymphatic system is lymphedema, where the lymph glands get backed up and can cause horrible swelling and even the loss of use of a limb if it gets too big.


I never knew much about the lymphatic system until I got in to high school and took biology and physiology. The lymphatic is a wonderful system to move things around the body, with one exception, cancer.
These lymph nodes typically fight infections of the throat, upper respiratory tract, or teeth. They are part of the lymphatic system, which is composed of lymphatic vessels and fluid, the tonsils, spleen, thymus gland, and clusters of lymph nodes located in the neck, underarm, and groin.
This burden can cause the lymph nodes in the head and neck to swell as the battle against the infection is waged. Swelling of the posterior cervical lymph nodes can sometimes be due to the spreading of head and neck cancers to these nodes. Lymphatic fluid travels all over the body collecting various components, such as proteins and bacteria, and carry it back to the lymph nodes for removal and destruction. Swollen lymph nodes are a clinical sign, in combination with other symptoms such as fever, congestion, and bodily aches, that the body is suffering from an infection.


When the posterior cervical lymph nodes are swollen without any associated signs of infection or occur in a person who has suffered from cancer in the past, a doctor should be seen immediately to determine the cause of the swelling. Without any other signs of infection, posterior cervical lymph nodes may also be enlarged due to the metastasis of cancerous cells. Enlarged posterior cervical lymph nodes typically suggest an infection of the throat, a viral infection, an infection of the upper respiratory tract, or an infection in a tooth. Most swollen lymph nodes will return to normal size following the infection, but if a lymph node remains swollen for more than two weeks and associated symptoms do not disappear, a doctor should be seen.
