Leukopenia

Leukopenia is a medical condition that is characterized by a decrease in the number of white blood cells (leukocytes) in a person’s blood. White blood cells are a key component of the immune system, and a decrease in leukocytes can impair the body’s ability to fight off pathogens. Leukopenia can be caused by various illnesses, including infections, cancer, and autoimmune disorders, as well as by medication or radiation therapy. It is also a common side effect of chemotherapy. As such, it is closely monitored in patients receiving treatment for cancer. Severe leukopenia can lead to increased risk of serious infections, which can often be fatal. To prevent and treat leukopenia, a doctor may prescribe medications to increase the number of white blood cells in the blood, or recommend lifestyle changes that boost the immune system.
