    U.S.:
    New Cases: 222,520
    Deaths: 157,300
  • 3. Lung Cancer Biology
    Carcinoma
    Cancer that begins in the skin or in the tissues of the organ (this case the lung)
    Genetic alteration
    Lack of equilibrium between oncogenes and proto-oncogenes
  • 4. Lung Cancer
    Small Cell
    Non-Small Cell
    Small Cell Carcinoma
    (Oat cell Cancer)
    Combined Small Cell Carcinoma
    Squamous Cell Carcinomas
    Adenocarcinomas
    Mixed Small Cell/Large Cell Carcinoma
    Large Cell Carcinomas
  • 5. Small Cell Lung Cancer (SCLC)
    15% is SCLC
    Most aggressive
    Due to smoking
    Metastasizes quickly
    Has most likely spread by the time diagnosed
  • 6. SCLC Treatment
    Chemotherapy
    Radiation Therapy
    Both used to relieve symptoms, not cure it
    Very deadly
    Only 6% live after five years of diagnosis
    Treatment often prolongs life for 6-12 months
    Prevention:
    Stop smoking
    Don’t start smoking
  • 7. Non-Small Cell Lung Cancer (NSCLC)
    Most common form of lung cancer
    Caused by environmental factors
    Smoking, secondhand smoke, air pollution, poor drinking water, etc.
    Treatment:
    Depends on the stage
    Surgery often first line of treatment
    Chemotherapy, laser therapy or photodynamic therapy
  • 8. NSCLC (cont.)
    Expectations:
    NSCLC grows slowly
    Stage I:
    Cured with surgery
    50% cured
    Stage II
    Can be cured in some cases
    Stage IV:
    Almost never cured
    Helped to extend and improve quality of their lives
