Blood Count

Some types of cancer treatment may affect a patient's blood counts.

  • White blood cells help to fight infections.
  • Platelets prevent bleeding and bruising.
  • Red blood cells carry oxygen throughout a patient's body.

Low blood counts can be treated, but treatment options may be different for each patient based on severity and health history. Patients should discuss treatment options with their doctors if they experience any of the following symptoms:
