During treatment for breast cancer, you will have routine blood tests called complete blood counts (CBC). One important part of the count is your neutrophils. If your neutrophils are low (neutropenia), they can be boosted to help your immune system recover. Treatment for neutropenia is usually injections of Neulasta, Neupogen (filgrastim), or Leukine (sargramostim).
