Targeted therapy is a type of cancer treatment that targets proteins that control how cancer cells grow, divide, and spread. It is the foundation of precision medicine. As researchers learn more about the DNA changes and proteins that drive cancer, they are better able to design treatments that target these proteins.

 Targeted therapies are classified as either small or large molecule drugs.

• Small molecule drugs are tiny enough to enter a cancer cell once they find it. They work by targeting a specific substance inside the cell and blocking it.
• Large molecule drugs usually can’t fit into a cell. They work by attacking then weakening or destroying proteins or enzymes on the surface of the cell. They are often described as a “lock and key” because the molecule is like a key that opens the enzyme or protein on the surface of the cell like a lock. The key fits into the lock, allowing the drug to work.
