Targeted Therapy for Cancer in Delhi – A Precision Approach to Treatment
Cancer is a complex, multifactorial disease that arises from a variety of genetic, environmental, and lifestyle factors. Traditionally, treatments like surgery, chemotherapy, and radiation therapy have been the mainstay, aiming to remove or destroy cancer cells. While these methods remain effective, advancements in oncology have introduced a more refined approach—Targeted Therapy for Cancer in Delhi—which focuses on the specific molecular changes that distinguish cancer cells from healthy ones.
Unlike conventional chemotherapy, which affects all rapidly dividing cells (including healthy ones), targeted therapy works like a “sniper,” aiming precisely at cancer-specific mechanisms. This reduces damage to normal cells, often resulting in fewer side effects and potentially better outcomes for eligible patients.
-
Blocking Abnormal Growth Signals – Many cancers grow because of overactive signaling pathways. For example, HER2-positive breast cancers produce excessive HER2 protein. Targeted drugs like trastuzumab can block these signals, slowing or stopping cancer progression.
-
Preventing Blood Supply to Tumours – Some targeted therapies inhibit angiogenesis, cutting off the tumour’s oxygen and nutrient supply by blocking VEGF (vascular endothelial growth factor).
-
Triggering Cancer Cell Death – Certain drugs induce apoptosis (programmed cell death) in cancer cells or block survival pathways.
-
Delivering Toxins Directly to Cancer Cells – Some monoclonal antibodies carry chemotherapy or radioactive substances directly to cancer cells, minimizing harm to healthy tissues.
Eligibility for Targeted Therapy:
Not all cancers can be treated with targeted therapy. A detailed molecular or genetic test—through a tissue biopsy or liquid biopsy—is essential to detect the presence of specific proteins, mutations, or abnormal pathways.
Examples of Successful Targeted Therapy Applications Include:
-
EGFR, ALK, or ROS1 mutations in non-small cell lung cancer
-
BRAF mutation in melanoma
-
HER2 overexpression in breast cancer
Types of Targeted Therapy Drugs:
-
Monoclonal Antibodies – Engineered immune proteins that bind to cancer cell targets (e.g., Rituximab for lymphoma).
-
Small-Molecule Inhibitors – Oral drugs that penetrate cancer cells to block abnormal proteins (e.g., Imatinib for chronic myeloid leukemia).
Advantages:
-
Precision – Targets cancer-specific pathways.
-
Fewer Side Effects – Less harm to normal cells.
-
Convenience – Many drugs are oral and don’t require hospitalization.
-
Improved Outcomes – Can significantly extend survival in eligible patients.
Limitations:
-
Drug resistance can develop over time.
-
Availability of molecular testing may be limited in certain areas.
-
Not effective for all cancer types.
-
Targeted therapy cost in Delhi can be higher than conventional treatments due to advanced technology and specialized drugs.
The targeted therapy cost in Delhi varies depending on the cancer type, drug choice, duration of treatment, and whether the medication is branded or generic. On average, the monthly cost can range from moderate to high, but many cancer centers offer financial counseling, insurance support, or access to patient assistance programs to make treatment more affordable.
The Future of Targeted Therapy:
With rapid advancements in genetic testing, artificial intelligence, and drug development, Targeted Therapy for Cancer in Delhi is expected to become even more accessible and effective. Future strategies may include combining targeted therapy with immunotherapy, chemotherapy, or radiation for better, longer-lasting results.
In conclusion, targeted therapy represents a major leap forward in cancer treatment—offering hope, precision, and improved quality of life for many patients. While not a universal solution, it is a vital component of modern oncology, particularly when delivered in specialized cancer centers with expertise in precision medicine.
