Leukemia is a cancer of blood-forming cells in the bone marrow that leads to an overproduction of abnormal white blood cells. These cells crowd out healthy blood cells, affecting the body's ability to fight infection, carry oxygen, and stop bleeding. There are several types of leukemia, classified by how quickly they develop and which blood cells they affect. Understanding what leukemia is, how it develops, and what the different types mean helps you grasp the medical information you may encounter when learning about this condition.

The articles here explain how doctors diagnose leukemia, what symptoms to recognize, and how current treatments work—from chemotherapy and targeted drugs to stem cell transplants. You'll find information about what to expect during treatment, how survival rates vary by type and age, and the physical and emotional challenges people face during and after care. These guides are meant to help you understand the condition itself and the medical landscape surrounding it.
