Why might it be that only one lymph node be swollen?
2 doctors weighed in across 2 answers
Infection or tumor: The usual cause is some infection in the area drained by that node. Less commonly tumors may present as a swollen node.

Monitoring Centers: Lymphatic system absorbs/carries things too big to go into the arteries/veins like bacteria eaten by white cells and digested food. Lymph nodes "taste" the lymph for anything bad like bacteria/viruses/cancers, etc. When it detects a problem, it alerts the immune system and your body reacts. They enlarge in response to the inflammation they create when they react. They shrink when all is well.
