Computer Tomography (CT) scan: This is an X- ray procedure enhanced by computer. The results are three dimensioned scan through a body part showing bone and body tissue.
DNA: The abbreviation for "deoxyribonucleic acid," the primary carrier of genetic information found in the chromosomes of almost all organisms.

Stem Cell Transplantation: A method of replacing immature blood-forming cells that were destroyed by cancer treatment. The stem cells are given to the person after treatment to help the bone marrow recover and continue producing healthy blood cells.
