        • Relieve obstruction
        • Improve the sense of well-being
  • Effect on cells
    • Effective against dividing cells, so cancer cells escape death by staying in G0 phase (resting phase)
    • Problem: Presence of drug-resistant resting and non-cycling cells
    • As tumors get bigger, more cells become inactive and convert to G0
    • Chemotherapy agents cannot distinguish between normal and
      cancer cells
    • Side effects are result of destruction of normal cells
