  4. What is the only difinitive means of diagnosing cancer
    Biopsy
  5. What is the name of a cancer that begins in the cells of the immune system?
    lymphoma or myloma
  6. cancer that starts in blood-forming tissue such as the bone marrow and causes large numbers of abnormal blood cells to be produced and enter the blood.
    Leukemia
  7. What are the 3 main factors that cancers are staged on
    • The size of the primary tumor
    • Whether the tumor has spread to the lymph nodes
    • Whether the tumor has spread to distnant areas
  8. Cachexia
    extreme body wasting and malnutrition
  9. What is Prophylactic surgery
    the removal of “at-risk” tissue to prevent cancer development.
  10. What is diagnostic surgery
    • removal of all or part of a suspected lesion for examination and testing. It provides proof of the presence of cancer.
    • Biopsy
  11. Curative Surgery
    focused on removal of all cancer tissue.
  12. What is cancer control or cytoreductive surgery?
