|  | The symptoms of blood cancers are very general. It is always important to remember that nearly all of these symptoms have much more common causes like infections or iron deficiency. Also, a person with a blood cancer can have any combination of the following symptoms, or very few.
 | Fever |  | Drenching night sweats |  | Weight loss (>10% body weight in 6 months) |  | Itching |  | Fatigue |  | Breathlessness |  | Bleeding from gums/nosebleeds/heavier periods |  | Bruising |  | Recurrent infections |  | Bone pain |  | Enlarged lymph nodes |  | Pain in the abdomen (due to enlarged liver/spleen) |  | Pain in enlarged nodes immediately after drinking alcohol (Hodgkin’s lymphoma only) |

|  | Leukaemia and Lymphoma can only be diagnosed using laboratory tests. Blood cancer can never be diagnosed by symptoms alone.
Leukaemia cells crowd the bone marrow meaning too few of the other types of blood cell can be produced. A lack of red blood cells is called anaemia and causes symptoms such as fatigue and breathlessness.
