What causes Waldenstrom’s macroglobulinaemia?
WM is caused when a certain type of white blood cell – called B-cells – develops incorrectly. Even though these abnormal cells aren’t of any use to the body, they keep on multiplying and can crowd out the other useful blood cells. This build-up of abnormal B-cells creates some of the common symptoms felt by people with WM, such as fatigue, increased infections and unexplained bruising.
