normal size lymph node in neck
Most normal lymph nodes are about 1cm in size (0.5 to 2.0cm) but that size varies depending on the location of the node, and what activity is going on.Infections, cancer and many other conditions can cause it to expand as the immune system reacts to the problem.ymph nodes are body organs (not glands) spread throughout your body. Their function is to filter out all the dead bacteria, viruses, and other dead tissue from the lymphatic fluid and eliminate it from the body. They are also the place where the white blood cells (lymphocytes) spend much of their time.
