What could cause a lymph node to enlarge?

Lots of things: Swollen lymph nodes may be swollen due to inflammation, infection, lymphoma, cancer, sarcoid or castlemann's disease. I am sure there are other possibilities but off the top of my head these seem to be the most common.

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.
