Symptoms of acute lymphoblastic leukaemia
The main symptoms of ALL are caused by the increased number of immature cells (blast cells) in the blood, which reduces the number of normal blood cells.
These are the main symptoms of ALL
Looking pale - which may be due to anaemia caused by a lack of red blood cells.
Feeling very tired - even breathless, at the slightest effort.
Feeling generally unwell and run-down - perhaps with a sore throat or mouth.
Aching joints and bones - as the bones can be affected by leukaemia cells.
Having various infections one after the other - caused by a lack of healthy white blood cells.
Unusual bleeding - caused by a reduction in the number of platelets. This may include bruising (bruises may appear without any apparent injury), heavy periods in women, bleeding gums and frequent nosebleeds.
Occasionally, a person will not have any of these symptoms and the leukaemia is discovered during a routine blood test.
Symptoms may appear very quickly over a few weeks, and treatment needs to be given as soon as possible. If you have any of these symptoms you should have them checked by your doctor, but remember they are common to many illnesses other than leukaemia.
