When you come for treatment at Missouri Cancer Associates, your care team will often draw a blood sample to monitor your health. This blood work includes a comprehensive metabolic panel (CMP) and a complete blood count (CBC).
Red Blood Cells (RBCs)
Red blood cells carry oxygen throughout the body. A decrease in red blood cells can occur due to cancer, treatment, kidney issues, poor nutrition, or other health problems. Symptoms of a low red blood cell count include shortness of breath, weakness, excessive fatigue, dizziness, or lightheadedness. If you experience any of these symptoms or a racing heartbeat, contact your provider. Persistently low red blood cell counts may require a blood transfusion.
Platelets
Platelets help your blood to clot. A low platelet count increases the risk of bruising and bleeding. Platelets can decrease due to cancer, treatment, or certain medications. If your platelet count is low, your provider may recommend special precautions:
- Use a soft toothbrush.
- Use an electric razor to avoid cuts.
- Blow your nose gently.
- Keep your nails short and use care when cutting them.
- Avoid constipation.
- Avoid situations where injury may occur.
Contact your provider if you notice unusual bleeding or bruising, frequent nosebleeds, bleeding gums, or blood in your urine or stool. Persistently low platelet counts may necessitate platelet transfusions.
White Blood Cells (WBCs)
White blood cells fight infections. Some cancer treatments, such as chemotherapy, can lower your white blood cell count, typically decreasing 8 to 12 days following treatment and then rebounding. A low white blood cell count compromises your immune system, making you more susceptible to infections and fevers. Prevent infections by:
- Practicing good hand hygiene (wash hands with soap and warm water before eating or preparing food).
- Avoiding people who are ill.
- Staying up-to-date on vaccinations (ask your provider if there are any you should avoid).
- Following food safety precautions (wash fruits and vegetables well and cook all meat, poultry, and fish thoroughly).
Contact your provider if you have any of the following symptoms:
- Fever greater than 100.4°F.
- Cold or flu-like symptoms.
- Chills or sweats.
- Productive cough.
- Red or draining wound.
- White coating in your mouth.
- Burning, difficulty, or frequency with urination.
