ANATOMY

Detailed explanation-1: -Leukemia usually involves the white blood cells. Your white blood cells are potent infection fighters-they normally grow and divide in an orderly way, as your body needs them. But in people with leukemia, the bone marrow produces an excessive amount of abnormal white blood cells, which don’t function properly.

Detailed explanation-2: -Leukemia, a type of cancer found in your blood and bone marrow, is caused by the rapid production of abnormal white blood cells. The high number of abnormal white blood cells are not able to fight infection, and they impair the ability of the bone marrow to produce red blood cells and platelets.

Detailed explanation-3: -Bone marrow cancer includes leukemias and multiple myeloma.

Detailed explanation-4: -Lymphocytic leukemia (also known as lymphoid or lymphoblastic leukemia) develops in the white blood cells called lymphocytes in the bone marrow. Myeloid leukemia (also known as myelogenous leukemia) may also start in white blood cells other than lymphocytes, as well as red blood cells and platelets.

Detailed explanation-5: -Most often, leukemia is a cancer of the white blood cells, but some leukemias start in other blood cell types. There are several types of leukemia, which are divided based mainly on whether the leukemia is acute (fast growing) or chronic (slower growing), and whether it starts in myeloid cells or lymphoid cells.
