Bone marrow damage refers to injury or dysfunction of the soft tissue inside bones that produces blood cells including white blood cells, red blood cells, and platelets. It is caused by chemotherapy, radiation therapy, autoimmune disorders, infections, toxins, or certain medications that destroy bone marrow stem cells. The White Blood Cell Count (WBC) is the most important test for monitoring bone marrow damage because it directly measures the bone marrow's ability to produce essential infection-fighting cells.

Bone marrow damage is caused by chemotherapy drugs, radiation therapy, autoimmune disorders like aplastic anemia, viral infections such as Epstein-Barr virus or hepatitis, exposure to toxins like benzene, and certain medications including antibiotics and anticonvulsants. Cancer treatments are the most common cause, as chemotherapy and radiation deliberately target rapidly dividing cells, which unfortunately includes the stem cells in bone marrow that produce your blood cells. Other causes include bone marrow diseases like myelodysplastic syndromes, vitamin deficiencies, and inherited genetic conditions that affect blood cell production.
The White Blood Cell Count (WBC) is the most important blood test for monitoring bone marrow damage because it directly measures the bone marrow's ability to produce white blood cells that fight infections. When your bone marrow is damaged by chemotherapy, radiation, or disease, your WBC count typically drops first and most dramatically, putting you at serious risk for life-threatening infections. A complete blood count (CBC) that includes WBC, red blood cell count, and platelet count provides a comprehensive view of all three cell types produced by bone marrow, helping your doctor assess the full extent of bone marrow function and recovery. Regular WBC monitoring is essential during cancer treatment to determine when your immune system is too compromised and treatment adjustments are needed.
You should get tested if you are undergoing chemotherapy or radiation therapy, experiencing unexplained fatigue and weakness, having frequent or severe infections, noticing unusual bruising or bleeding that does not stop easily, or have been exposed to toxic chemicals or high doses of certain medications. Testing is particularly important if you develop fever during cancer treatment, as this may indicate a dangerously low white blood cell count requiring immediate medical attention. Anyone with autoimmune disorders affecting blood cells or a family history of bone marrow diseases should also consider regular monitoring to catch problems early when treatment is most effective.
