What kind of cancer is leukemia classified as?

Leukemia is classified as blood cancer because it originates in the bone marrow and disrupts the production of blood cells. Specifically, it primarily affects the white blood cells, which are crucial for the body's immune response. In leukemia, the bone marrow produces abnormal white blood cells that do not function properly, leading to various health complications. This classification as blood cancer distinguishes it from other types of cancer, such as skin cancer, lung cancer, or soft tissue cancer, which originate in different types of tissues within the body. Understanding leukemia's classification helps in recognizing its symptoms, treatment options, and the overall impact it has on the body's blood-forming systems.
