  1. Angiogenesis
    Formation of new blood vessels; one mechanism by which cancer spreads
  2. Apoptosis
    Programmed cell death involving a cascade of specific cellular events leading to death and destruction of the cell
  3. Benign
    Form of a tumor not capable of spreading throughout the body
  4. Bone Marrow Transplant
    A cancer patient's stem cells are harvested and stored before chemotherapy beings. Then, the stored cells are returned to the patient by injection
  5. Cancer
    Malignant tumor whore nondifferentiated cells exhibit loss of contact inhibition, uncontrolled growth, and the ability to invade tissue and metastasize
  6. Carcinogen
    Environmental agent that causes mutations leading to the development of cancer
  7. Carcinogenesis
    Development of cancer
  8. Carcinoma
    Cancer arising in epithelial tissue
  9. Cyclin
    Protein that regularly increases and decreases in concentration during the cell cycle
  10. Growth Factor
    Chemical signal that regulates mitosis and differentiation of cells that have receptors for it; important in such processes as fetal development, tissue maintenance and repair, and hematopoiesis; sometimes a contributing factor in cancer
  11. Initiation
    Mutation of a single cell that may lead to cancer development
  12. Leukemia
    Cancer of the blood-forming tissues leading to the overproduction of abnormal white blood cells.
  13. Lymphoma
    Cancer of lymphatic tissue (reticular connective tissue).
  14. Malignant
    Form of tumor capable of spreading throughout the body
  15. Metastasis
    Spread of cancer from the place of origin throughout the body; caused by the ability of cancer cells to migrate and invade tissues
  16. Mutagen
    Agent, such as radiation or a chemical, that brings about a mutation
  17. Oncogene
    Cancer-causing gene
  18. Oncologist
    Physician who specializes in one or more types of cancers
  19. Oncology
    The study of cancer
  20. Progression
    In cancer, a second mutation that allows cells to invade surrounding tissues
  21. Promotion
    In cancer, develoment of a group of cells from a single mutated cell.
  22. Proto-oncogene
    Normal gene that can become an oncogene through mutation
  23. Sarcoma
    Cancer that arises in muscles and connective tissues
  24. Telomere
    Tip of the end of a chromosome
  25. Tumor
    Cells derived from a single mutated cell that has repeatedly undergone cell division; benign tumors remain at the site of origin, and malignant tumors metastasize
  26. Tumor Marker Test
    Blood test for a substance, such as a tumor antigen, that indicates a patient has acancer
  27. Tumor-Supressor Gene
    Gene that codes for a protein that ordinarily suppresses cell division; inactivity can lead to a tumor
