What is Leukemia?

Leukemia

Quick Answer

It is a type of cancer that affects the blood and bone marrow. This disease causes the body to produce abnormal white blood cells, which can interfere with normal blood functions.

Overview

Leukemia is a cancer that starts in the blood-forming tissues, particularly the bone marrow. It leads to the production of large numbers of abnormal white blood cells, which do not function properly. This can result in a weakened immune system, making the body more susceptible to infections and other health issues. The abnormal cells crowd out healthy blood cells, which can cause problems like anemia, bleeding, and bruising. There are different types of leukemia, including acute and chronic forms, which can affect both children and adults. For example, acute lymphoblastic leukemia is common in children and requires immediate treatment to improve the chances of recovery. Understanding leukemia is crucial because it can have serious health implications if not diagnosed and treated early. The treatment often involves chemotherapy, radiation, or stem cell transplants, and ongoing research is aimed at finding more effective therapies. Awareness of leukemia can help in early detection and better outcomes for those affected.
