Targeted Therapy For Cancer
Cancer therapy has significantly undergone a major transformation over recent years, and one of the most recent treatments used in treating cancer is known as targeted therapy. This treatment is currently the leading model in modern oncology practices. Though traditional ways of treating cancer such as chemotherapy and radiation therapy are still effective, targeted therapy has provided patients with an opportunity of getting treated differently. In India, where cancer treatment costs can vary significantly, targeted therapy is becoming increasingly accessible, with costs ranging from 1100 USD to 3600 USD per month, making it a viable option for many patients when compared to overall cancer treatment costs in India.
Unlike normal chemotherapy, which harms both normal and cancerous cells, targeted therapy works like a missile, home in the cancerous cells without affecting normal cells. This has helped turn the tide on cancer treatment since it has given prognosis to patients who were not likely to benefit from conventional treatment strategies.
Why is Targeted Therapy Used in Cancer Treatment?
Targeted therapy for cancer is used as for several compelling reasons:
- Precision Treatment: The drugs are designed to interact with specific molecules involved in cancer growth and survival.
- Customized Approach: Treatment can be tailored to the unique characteristics of each patient’s cancer.
- Enhanced Effectiveness: When combined with other treatments, it often improves overall outcomes.
- Reduced Collateral Damage: By targeting specific cancer-related molecules, healthy cells are less affected.
How Targeted Therapy Work?
Targeted therapies are designed to identify and attack specific components or areas within cancer cells, or to detect and inhibit particular signals that prompt a cancer cell to proliferate. The elements within cancer cells that serve as “targets” for these therapies include:
- An excess of a specific protein present on a cancer cell
- A protein found on a cancer cell that is absent in normal cells
- A mutated protein that has undergone changes in a cancer cell
- Alterations in genes (DNA) that are not present in normal cells.
The mechanisms of action for targeted drugs can include:
- Inhibiting or deactivating chemical signals that instruct the cancer cell to grow and replicate
- Altering proteins within cancer cells to induce cell death
- Inhibiting the development of new blood vessels that provide essential nutrients to cancer cells.
- Enhancing the immune response to target and destroy cancer cells.
- Administering toxins directly to cancer cells while protecting healthy cells.
The effectiveness and side effects of these drugs can vary based on their mechanisms of action and the specific targets they address.
It is noteworthy that certain targeted therapy agents, such as monoclonal antibodies, may function through multiple pathways to manage cancer cells and can also be classified as immunotherapy due to their ability to enhance the immune response.

Targeted Therapy For Cancer Why is it Necessary?
Your oncologist might recommend targeted therapy in several situations:
- Specific Cancer Types: Particularly effective for certain breast, lung, colorectal, and blood cancers
- Genetic Markers: When cancer cells have specific genetic mutations that can be targeted
- Advanced Stages: Often used when cancer has spread or returned
- Combination Treatment: Can be used alongside surgery, chemotherapy, or radiation
Risks and Side Effects
While targeted therapy generally has fewer side effects than traditional chemotherapy, patients should be aware of potential complications:
Common Side Effects:
- Skin problems (rash, dry skin)
- High blood pressure
- Blood clotting issues
- Wound healing problems
- Fatigue
- Diarrhea.
Serious Risks (Less Common):
- Liver problems
- Heart problems
- Vision changes
- Risk of infection.
The Future of Targeted Therapy
Research in targeted therapy continues to advance, promising:
- More effective treatments
- Broader availability of options
- A better understanding of the patient selection
- Improved side effect management
- More affordable treatment options
Conclusion
Targeted therapy for cancer marks a notable progression in the treatment of cancer; however, it is essential to explore all available options with your healthcare team. They can assist in evaluating whether this treatment is suitable for you, taking into account both medical and financial considerations. It is crucial to recognize that each cancer experience is distinct, and what may be the most effective approach for one individual might not necessarily be the best option for another.
