Targeted Therapy
Targeted therapy is a type of cancer treatment that uses drugs designed to specifically identify and attack cancer cells while doing minimal damage to normal, healthy cells.
Unlike chemotherapy, which affects all rapidly dividing cells, targeted therapy focuses on specific molecular targets—such as proteins or genes—that contribute to cancer growth and progression. Examples include small molecule inhibitors (which can enter cancer cells to block signals that tell them to grow) and monoclonal antibodies (which target specific proteins on the surface of cancer cells).
Before treatment, patients may undergo biomarker testing to determine if their cancer has specific targets that make them eligible for these therapies.
