What is Targeted Therapy?
• A type of cancer treatment that works by focusing 
on specific targets in cancer cells.
• Unlike chemotherapy, it does not damage most 
normal cells.
• Works at the molecular and genetic level.
• Often called personalized medicine.

How Does It Work?
• Identifies abnormal genes or proteins in cancer 
cells.
• Blocks signals that make cancer cells grow and 
spread.
Types of targeted therapy:
     1. Monoclonal antibodies (lab-made proteins that 
attack   
      cancer cells).
     2. Small molecule drugs (block signals inside 
cells).

How is It Used in Cancer 
Treatment?
• As primary treatment – to shrink tumors.
• Before surgery/chemo (neoadjuvant) – to make 
tumors smaller.
• After treatment (adjuvant) – to prevent 
recurrence.
• For advanced cancers – to control spread and 
symptoms.
• Often combined with - chemo, radiation, or
