Waldenstrom's macroglobulinaemia (WM) is sometimes called lymphoplasmacytic lymphoma and is one of the family of cancers of the lymphatic system known as Non-Hodgkins lymphoma (NHL). Doctors may use any of these terms when discussing your WM with you.
It is a slow-growing cancer with its own distinct characteristics that require specialised treatment and care.
Jan Waldenström was the Swedish doctor who first described the disease in 1944 and lent it his name; “macroglobulinaemia” refers to the high levels of immunoglobulin M (IgM) seen in the blood stream of 95% of WM patients.
IgM is natural, it is produced by B cells in the bone marrow to fight infection. However, in WM, defective ‘B’ cells produce large quantities of non-functional IgM paraproteins which are not useful to the body and can cause damage.
