<s>[INST] thamk you; my 46 yo wife is in round 7 of chemo today as a result of colon cancer and was told her white cell count was 2.9 the oncologist maintained though to push on with treament . what point is it necessary to delay treatment on ythe scale he refrs to where she is 2.9? [/INST] Her WBC count is 2900 due to myelosuppression caused by the chemotherapy medications. Chemotherapy can only be administered if the absolute neutrophil count is more than 1500.ANC is the no of WBC multiplied by % of neutrophils in blood. To find out ANC u have to do a blood test called CBC/differential count. I would suggest u wait for sometime for your counts to improve or use granulocyte colony stimulating factors to increase the count and then administer chemotherapy. Regards Chat Doctor.  </s>
