🔍 When Do Doctors Recommend Targeted Therapy?
-
Based on Biomarker Testing
-
Before prescribing targeted therapy, doctors usually order biomarker or genetic testing on a biopsy or blood sample.
-
If the cancer shows certain mutations (for example, HER2 in breast cancer, EGFR in lung cancer, or BRAF in melanoma), targeted therapy may be the best option.
-
-
When Standard Chemotherapy Isn’t Effective
-
If chemotherapy alone does not control the disease, doctors may shift to or add targeted therapy.
-
-
In Combination with Other Treatments
-
Targeted therapy is often combined with chemotherapy, radiation, or immunotherapy to increase overall effectiveness.
-
-
For Advanced or Metastatic Cancer
-
When cancer has spread to other parts of the body, targeted therapy can slow down progression and improve quality of life.
-
-
As Maintenance Therapy
-
After initial treatment, doctors may recommend targeted therapy to reduce the risk of recurrence.
-
✅ Benefits of Targeted Therapy
-
Attacks cancer cells more precisely.
-
Often fewer side effects compared to chemotherapy.
-
Can improve survival rates and quality of life.
-
Personalized treatment tailored to each patient.
⚠️ Things to Keep in Mind
-
Not every patient is eligible – the cancer must have specific genetic changes.
-
Treatment can be costly.
-
Over time, some cancers may develop resistance, which may require a change in therapy or combination approaches.
Conclusion
Targeted therapy is a powerful and advanced treatment option in modern cancer care. However, it works best for patients whose tumors show particular genetic markers. If you or a loved one has been diagnosed with cancer, speak with your oncologist about biomarker testing to find out whether targeted therapy could be part of the treatment plan.
