White Blood Cells Protect YouWatch this video of how white blood cells protect against infection by attacking germs that enter your body. Chemotherapy and White Blood CellsWhen the number of neutrophils is reduced, a condition called neutropenia occurs and your risk for getting an infection is increased. Between 7-12 days after you finish each chemotherapy dose—and possibly lasting for 5-7 days, your white blood cells are at their lowest numbers. This period of time is often called your nadir, meaning “lowest point”. This is when you are more likely to develop neutropenia. This period varies slightly depending upon the chemotherapy drug, or combination of drugs, used. Your doctor and/or nurse will let you know exactly when your white blood cell count is likely to be at its lowest. You should watch very carefully for signs and symptoms of infection during this time. During these high-risk days, you should take your temperature any time you feel warm, flushed, chilled, or not well.

If You Have a Low White Blood Cell Count (High Risk)If chemotherapy is likely to make your white blood cell count very low, you may get medicine to raise your white blood cell count and help lower your risk of infection. Remember that when your white blood cell count is low, your body isn’t as well equipped to fight off germs. For this reason, it is very important to reduce your risk of infection and familiarize yourself with the signs and symptoms of infection. Low blood cell counts can be a serious complication during cancer treatment. Know why your doctor closely tracks your blood cell counts. By Mayo Clinic StaffYour doctor may monitor your blood cell counts carefully during your cancer treatment. There's a good reason you're having your blood drawn so often — low blood cell counts put you at risk of serious complications. What's measured in a blood cell count?If you're undergoing certain cancer treatments that could cause low blood cell counts, your doctor will likely monitor your blood cell counts regularly using a test called a complete blood count with differential (CBC w/diff). Low blood cell counts are detected by examining a blood sample taken from a vein in your arm. When checking your blood cell count, your doctor is looking at the numbers and types of the following:
What causes low blood cell counts?Common cancer-related causes of low blood cell counts include:
What are the complications of low blood cell counts?Low blood cell counts may delay your next round of treatment or lead your doctor to reduce medication dosage or prescribe a new medication.

How can you tell if you have low blood cell counts?Unless your blood cell counts are very low, you probably won't experience any signs or symptoms and you won't be able to tell that your blood cell counts are down. That's why your doctor may order frequent blood tests to follow your blood cell counts. Ask your doctor whether your cancer treatment is likely to cause low blood cell counts and what signs and symptoms you should be looking for. If you notice any signs or symptoms of low blood cell counts, tell your doctor right away.
