Lymph nodes swelling and it is not cancer but they are still swollen. what is the best course of action?

You need a good doct: You should be seeing a physician who can measure the size of the lymph nodes and follow them once every month or two and look for changes in the size. If the size does not increase, you do not need to do anything. If the size is steadily increasing a biopsy of the lymph node may be indicated to find out the cause. We can not exclude cancer of the lymph nodes without a biopsy....If the node is >2cm.

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.
