  2. anemia
    a condition in which thier is a reducton in the number of red blood cells, the amount of hemoglobin, or the volume of packed red cells in the blood, resulting in a diminished ability of the red blood cells to transport oxygen to the tissues
  3. aplastic anemia

  4. iron deficiency anemia
    a microytic-hypochromic type of anemia charactrerized by lack of iron, affecting production of hemoglobin and characterized by small red blood cells containing low amounts of hemoglobin
  5. pernicious anemia

  6. autoimmune diease

    any neoplastic disorder of lymph tissue, usually malignant, as in Hodgkin disease
  16. metastasis
    the process by which cancer cells are spread by blood or lymph circulation to distant organs

  18. polycythemia
    an increase in the number of erythrocytes and hemoglobin in the blood
  19. septicemia
    a systemic disease caused by the infection of microorganisms and their toxins in the circulating blood
  20. thrombocytopenia
    a bleeding disorder characterized by an abnormal decrease in the number of platelets in the blood, which impairs the clotting process
