What is neutropenia?

Neutropenia is a condition in which there is a low number of neutrophils—a type of white blood cell that helps your body fight infection.

During chemotherapy, there are times in your treatment cycle when your neutrophil count is particularly low, and you are at increased risk of infection. You will have blood tests to check for neutropenia, and medicine may sometimes be given to help prevent infection or to increase your white blood cells.

When your infection-fighting cells are low, everyday germs can be more dangerous, so steps like frequent handwashing and avoiding sick people matter. Your care team will explain how to protect yourself during these times.
