Neutropenia (say "noo-truh-PEE-nee-uh") means that your blood has too few white blood cells called neutrophils. White blood cells are an important part of your body's immune system. Neutrophils help protect your body from infection by killing bacteria.
Neutropenia is often caused by cancer treatments such as chemotherapy and radiation. These treatments destroy cancer cells. But they can also decrease your body's ability to make white blood cells.
Other causes include:

Even a mild infection can quickly become serious. So it's important to take extra measures to avoid infections and to be alert for signs of infection. Your doctor can tell you how long to keep up these precautions.

When you have neutropenia, it's important to take extra care to avoid infections, because you can get infections easily.
Your doctor can tell you the best ways to handle and prepare foods to help avoid infections. You may also need to avoid certain foods. For example, your doctor may tell you to:
