Targeted Therapy: Precision Medicine for Cancer Treatment
Introduction: Traditional cancer treatments like chemotherapy can be effective, but they often come with significant side effects because they attack both cancerous and healthy cells. Targeted therapy offers a more precise approach by targeting specific molecules involved in cancer growth. In this article, we’ll explore how targeted therapy works, its benefits, and its limitations.
How Targeted Therapy Works:
Targeted therapy focuses on specific genes, proteins, or the tissue environment that contributes to cancer growth and survival. By blocking these targets, the therapy can stop cancer cells from growing and spreading.
Types of Targeted Therapy:

How Targeted Therapy Works:
Targeted therapy focuses on specific genes, proteins, or the tissue environment that contributes to cancer growth and survival. By blocking these targets, the therapy can stop cancer cells from growing and spreading.
Types of Targeted Therapy:
- Monoclonal Antibodies: These are lab-made molecules that can bind to specific targets on cancer cells. Examples include Herceptin (for breast cancer) and Rituxan (for lymphoma).
- Small Molecule Drugs: These drugs can enter cells and block specific enzymes or proteins that cancer cells need to grow. Examples include Gleevec (for chronic myeloid leukemia) and Tarceva (for lung cancer).
- Angiogenesis Inhibitors: These drugs block the formation of new blood vessels that tumors need to grow. Examples include Avastin and Sutent.
- Precision: Targeted therapy specifically attacks cancer cells, sparing healthy cells and reducing side effects.
- Effectiveness: Targeted therapy can be highly effective for cancers with specific genetic mutations, such as HER2-positive breast cancer or EGFR-mutated lung cancer.
- Personalized Treatment: Targeted therapy is often tailored to the genetic profile of a patient’s tumor, making it a form of precision medicine.
- Resistance: Cancer cells can develop resistance to targeted therapy over time.
- Cost: Targeted therapy can be expensive, and not all patients have access to it.
- Limited Applicability: Targeted therapy is only effective for cancers with specific genetic mutations, which means it may not work for all patients.
