Acute lymphoblastic leukaemia (ALL)
We have a few different types of white cell which help us fight infection and disease. ALL is a cancer of one of these white cells, the lymphoid cells.
The most common symptoms are feeling tired, bruising and being prone to infection some people may also experience pain in their bones. The cause is unknown.
Blood tests, bone marrow samples and lumbar punctures are the tests that are used to diagnose ALL. Treatment includes chemotherapy, steroids and radiotherapy.
