If your level of red blood cells is low (anaemia), you may feel tired and need a blood transfusion to boost your red blood cell count. If you can't have blood transfusions your doctor may suggest that you have erythropoietin injections. Erythropoietin is a hormone that encourages the body to make red blood cells.
If your white blood cell count falls very low (which is rare), you may be more at risk of getting infections. You may need a short rest from treatment so that your blood count can go back to normal.
People having total body irradiation before bone marrow transplant or stem cell transplant will have low red cells as well as white cells and platelets. Platelets are cells that help the blood to clot and if they are low you may be more at risk of bruising or bleeding.
If your bone marrow is likely to be affected, you will have regular blood tests during your treatment to check the number of red blood cells in your blood.
