MICROANATOMY

Detailed explanation-1: -Cancer that forms in the blood-forming stem cells of the bone marrow (soft sponge-like tissue in the center of most bones). Bone marrow cancer includes leukemias and multiple myeloma.

Detailed explanation-2: -Osteosarcoma (also called osteogenic sarcoma) is the most common primary bone cancer.

Detailed explanation-3: -Most blood cancers, also called hematologic cancers, start in the bone marrow, which is where blood is produced. Blood cancers occur when abnormal blood cells start growing out of control, interrupting the function of normal blood cells, which fight off infection and produce new blood cells.

Detailed explanation-4: -Myeloma, also called multiple myeloma, is a cancer of the plasma cells. Plasma cells are white blood cells that make antibodies that protect us from infection. In myeloma, the cells grow too much, crowding out normal cells in the bone marrow that make red blood cells, platelets, and other white blood cells.
