- Lymph node biopsy (lymph gland biopsy)Taking out a lymph node to look at it under the microscope. This is to see if it contains any cancer cells. It is a very small operation. It is normally done under a general anaesthetic, but you should be able to go home the same day.
- Lymph node dissectionRemoving lymph nodes from a particular area of the body. You may have this to see if the cancer has spread (find out the 'stage' of the cancer), or to remove cancer that is already in the lymph nodes.
- LymphadenectomyAn operation to remove lymph nodes.

- LymphokinesA collective name for the interleukin growth factors. The interleukins are produced mainly by T cells. They stimulate other cells of the immune system to grow and mature.
- LymphomaLymphoma is a cancer of the lymphatic system. There are two main types of lymphoma: Hodgkin's disease and non-Hodgkin's lymphoma.
