A leukaemia which develops following previous chemotherapy or radiotherapy or a pre-existing condition, such as myelodysplasia or polycythaemia rubra vera.
A general term to describe serious bacterial infection of the blood stream often associated with high fever.
The liquid part of the blood which remains after cells have been removed and the blood has been allowed to clot. The only difference between plasma and serum is that serum cannot form a clot. There are some blood tests which are normally done on serum and some on plasma.
Shingles, also known as herpes zoster, is an infection of a nerve and the skin around it. It is caused by the varicella-zoster virus, which also causes chickenpox. Anyone who has had Chickenpox can suffer from shingles. All CLL patients have a damaged immune system. This means that you can get shingles more often, it can spread through your body faster, and you could be in pain for some time.

The spleen is a body organ on the left of the body, just under the diaphragm. It is part of the lymphatic system and filters the blood of old red blood cells and bacteria and other foreign bodies. The spleen also acts as a store for platelets and contains lymph node tissue and many lymphocytes. The spleen is often enlarged in leukaemia and may be removed as part of treatment for some cancers.
Surgery to take out the spleen. This is sometimes done in leukaemia or lymphoma as part of a patient’s treatment.

The most primitive cells in the bone marrow from which all the various types of blood cell which develop into
Myeloid stem cells – become white blood cells called monocytes and neutrophils (a type of granulocyte)
Lymphoid stem cells – become white blood cells called lymphocytes
Erythroblasts – become red blood cells
Megakaryocytes – become platelets
Stem cell transplant
A procedure used to treat a variety of blood disorders including leukaemia, lymphoma and sometimes myeloma. The patient receives very high doses of chemotherapy and/or radiotherapy to treat the disease and suppress the immune system. This damages the bone marrow and makes the blood count fall. Replacement stem cells are taken from a matched donor – allogeneic stem cell transplant or from the patient themselves -autologous stem cell transplant under a general anaesthetic and returned to the patient through a vein (or central venous line) in a similar way to a blood transfusion. Peripheral blood stem cells are now used more commonly than bone marrow. Cord blood stem cells also may be used.
An injection into tissue immediately under the skin.
