Leukemia is a type of cancer that starts in blood-forming tissue, usually the bone marrow, and leads to the overproduction of abnormal white blood cells. These cells crowd out normal blood cells, impairing the body's ability to fight infections, transport oxygen, and control bleeding. Leukemia can affect people of all ages, but certain types are more common in children, while others are more prevalent in adults. Advances in treatment have significantly improved outcomes, offering various options for managing the disease effectively. Understanding leukemia, its risk factors, and the latest treatment options can empower patients and their loved ones to make informed decisions. Support networks, medical advancements, and personalized treatment plans provide hope and improved quality of life for those diagnosed with leukemia.
