Commonly asked questions regarding targeted therapy treatment

 

If you or a loved one has been recommended targeted therapy, it’s normal to have questions. The term itself can sound a bit technical, but the idea is actually quite simple: instead of attacking all fast-growing cells (like traditional chemotherapy), targeted therapy focuses only on the cancer cells — like a sniper instead of a shotgun.

Here, Dr. Joydeep Ghosh, a leading precision oncology doctor in Kolkata, answers some of the most common questions patients ask about this treatment.

What is Targeted Therapy Treatment?

Targeted therapy treatment, also known as precision therapy, is a cancer treatment that targets specific abnormalities in the cancer cells, disrupting their growth and preventing rapid spread, while causing minimal damage to healthy cells. These treatments are designed to attack the specific genetic changes or proteins that drive the growth of cancer cells in any particular type of cancer.

How is it Different from Chemotherapy?

Chemotherapy affects all fast-growing cells, good or bad. That’s why people often lose hair or feel tired. However, targeted therapy focuses only on cancer cells with specific changes or faults. This means fewer side effects and a more focused approach.

A precision oncology doctor in Kolkata will typically recommend targeted therapy after conducting specific tests to identify the mutations present in the cancer cells. This personalized approach ensures that the treatment is tailored to your unique cancer profile.

Who Can Get Targeted Therapy?

Not all cancers can be treated with targeted therapy. It depends on the type of cancer and whether the cancer cells have specific markers. For instance, lung cancer, breast cancer, and certain types of leukemia are among the cancers that can be treated this way. Your doctor may ask for a biopsy or genetic test. If the tumour has those markers, you could be a good fit.

How Does Targeted Therapy Work?

Targeted therapy works in a few innovative ways. Some block the signals that tell cancer cells to grow. Others stop new blood vessels from forming, which cuts off the cancer’s supply line. Some treatments starve the tumour by blocking the nutrients or hormones it needs. A few even help your immune system find and fight the cancer more effectively.

Types of Targeted Therapies

There are mainly two types. Small-molecule drugs are tiny and can slip into cancer cells to block harmful proteins. Monoclonal antibodies are larger and attach to proteins on the outside of cancer cells to stop them from growing.

Side Effects of Targeted Therapy

  • Skin: Rash, itching, dryness
  • Digestion: Nausea, vomiting, diarrhoea, constipation, mouth sores
  • Blood: Fatigue, infection risk, poor clotting
  • Nails & Hair: Nail sores, hair colour loss
  • Breathing: Cough, shortness of breath
  • Swelling: Face, limbs
  • Organs: Possible thyroid, liver, and kidney damage
  • Others: High BP, allergic IV reactions

Conclusion

Targeted therapy represents a significant advancement in cancer care, offering precision treatment with fewer side effects. If you’re considering this option, consulting a precision oncology doctor in Kolkata is crucial. This will allow you to explore personalized treatment options based on your cancer’s unique profile, helping you to make informed decisions about your care.
