I was diagnosed 10 month ago, and WBC was 21000 when diagnosed (stage A). I was checked blood every 3 months, and found increasing WBC 1000 for a month. Three month ago, my WBC was 27000, Hb and platelets number was normal, and presumably 30000 next blood test. In my case, WBC can be expected to increase 3000 in every blood test, so the blood test seems to be OK every 6 months or 1 year. Do people with stage A check blood every 3 months, or 6 months?
