Are leukemia and pernicious anemia the same thing?
Different. Pernicious anaemia is low red blood cells (anaemia) due to inability to absorb vitamin B12 (needed for blood cells) because of autoantibodies (molecules normally designed to stick to nasties like viruses, but instead made to attack normal parts of the body). Antibodies can be made against stomach cells (parietal cells) or the protein that is made by them and binds the B12 (intrinsic factor). Leukaemia is a cancer of white blood cells.
