A bone marrow is the material that fills the center of most bones which is where blood cells are made. Leukemia is basically a blood cancer where the cells do not form properly.

Blood cells form in the bone marrow and when too many blood cells form in the human body then Leukemia cancer is developed. There are three different types of blood cells that increase out of control and are produced in the bone marrow which are White blood cells [leukocytes], Red blood cells [erythrocytes] and Platelets. White blood cells are part of the immune system and help fight off infections. They too aid in the curing of sores, wounds and cuts. Red blood cells hold haemoglobin which carries oxygen and takes out carbon dioxide to and from the cells throughout different organs of the body. Platelets help poke holes in the blood vessels and form clots just as blood vessels are corrupted or damaged (What is Leukemia? par. 4 & 5).

When these cells in the bone marrow divide uncontrollably, they form more white blood cells than required and thus, lead to leukemia cancer.
