Lymphocytosis

Lymphocytosis is a medical term referring to an increase in lymphocytes, a type of white blood cell that plays a key role in the immune system. This condition can occur due to various factors, including infections, stress, autoimmune disorders, or certain cancers. When the body fights off infections, it may produce more lymphocytes to help in the defense. While lymphocytosis itself isn’t a disease, it can indicate an underlying health issue. A healthcare professional typically investigates these levels to determine the cause and appropriate treatment, if necessary.
