HI all, I have had a number of blood tests in quick succession - the last two less than six weeks apart. My wbc have gone from 13.4 to 17.5. Is this significant? I am very early stage and not being monitored for anything else I have booked another blood test for October as this sounds a big rise in a short time and if it keeps on going...... I know in terms of many of you would not sound serious but I am a little scared. What questions should I ask?
