Targeted Cancer Therapy in India (2026): The Complete Guide to Precision Cancer Treatment, Testing, Cost and Hospitals — for International Patients
If a report has told you your cancer carries a specific mutation — EGFR, HER2, ALK, BCR-ABL, BRAF — you've almost certainly heard the words "targeted therapy." And you've probably also been told it's hard to arrange, or hard to afford, where you live.
That's the gap this page closes. India is one of the few countries where advanced targeted cancer treatment is both widely available and genuinely affordable — the same drug classes, the same molecular testing, the same accreditation standards, without a long wait.
This is a long guide because the honest version of this topic is not short.
It covers what targeted therapy is, what it can realistically achieve, the test you cannot skip, how the drugs are actually taken, what happens when they stop working, what it costs here, and how to begin.

What Targeted Therapy Actually Is
Targeted therapy is a cancer treatment that attacks a specific fault inside or on the surface of the cancer cell — a mutated gene, an overactive protein, or a signal the tumour uses to grow — while largely sparing healthy cells.
Because it needs a defined target, it almost always begins with molecular testing of the tumour. Doctors also call it precision medicine or personalised medicine.
Standard chemotherapy, developed in the 1940s, is a blunt tool. It attacks anything in the body that divides quickly — cancer, but also hair follicles, gut lining and bone marrow. That is why chemo is so hard on people.
Targeted therapy, developed over roughly the last two decades, works the other way round. If chemotherapy is a bomb, targeted therapy is closer to a rifle with a scope. But a precise shot needs something to aim at — which is the whole reason the testing comes first.
Individual targeted drugs do different jobs.
Depending on the drug, they may block the growth signals a cancer cell depends on, stop it dividing, cut off the blood supply feeding the tumour, flag the cancer for the immune system, or carry a chemotherapy payload directly to the cancer cell.
This is what makes it personalised. Two patients with cancer in the same organ, at the same stage, can need completely different drugs — because the fault driving each tumour is different. We explain the fundamentals in plain terms here: What is targeted therapy? →

Send My Reports on WhatsApp →What Targeted Therapy Can Realistically Achieve
There are three reasons an oncologist gives targeted therapy: to cure the cancer, to control it for as long as possible, or to relieve symptoms and improve quality of life.
Which goal applies depends on the cancer type, its stage, its biomarkers and how far it has spread — and knowing which one your doctor intends is one of the most important questions you can ask.
Most websites skip this. We think it matters more than almost anything else on this page, because it shapes every decision that follows — including whether travelling for treatment makes sense for your family.
Doctors often avoid the word "cure" even when aiming for it, because it can take years to be certain. Palliative treatment can be given at any stage and is not a signal that treatment has been abandoned.
Chronic myeloid leukaemia is the clearest example. Before targeted therapy, it was usually fatal. After imatinib, many people now live with it for decades, managed by a daily tablet — much closer to a long-term condition like diabetes than to a terminal diagnosis.
That is what long-term control can look like when the target is right.
Targeted Therapy vs Chemotherapy
Chemotherapy is toxic to most fast-dividing cells and rarely requires genetic testing first. Targeted therapy acts on one specific molecule in the cancer cell and almost always requires it.
Neither is universally better: many patients receive both, together or in sequence, and the choice depends on the tumour's biology rather than on which treatment sounds more modern.
Both are systemic treatments — they travel through the bloodstream and can reach cancer anywhere in the body. That makes them different from local treatments like surgery and radiotherapy, which act on one area only.
Targeted therapy is often gentler than chemotherapy — but it is not automatically safer. Serious side effects, including heart, lung, liver, bleeding and immune-related problems, do occur with some targeted drugs.
"Targeted" describes how the drug works, not a guarantee of an easy ride. Anyone promising you a side-effect-free cancer treatment is overselling.
We go deeper into how the two compare, and when each is used, here: Targeted therapy vs chemotherapy — the full comparison →
The Main Families of Targeted Drugs
Targeted drugs split into two broad structural groups — monoclonal antibodies, which are large and act on the cell surface, and small-molecule inhibitors, which are small enough to work inside the cell.
Within those, drugs are grouped by what they do: blocking growth signals, cutting off blood supply, blocking DNA repair, or delivering chemotherapy directly to the cancer cell.
There is a naming shortcut that holds up surprisingly often. Generic names ending in -mab are monoclonal antibodies, usually given as an infusion. Names ending in -ib are inhibitors, usually taken as a tablet.
Grouping them by what they do is more useful clinically — and this is where most patient guides stop short. These are the working categories your oncologist will recognise.
These groups overlap. A single drug can belong to more than one family — some monoclonal antibodies also act as growth blockers, and some also work as immunotherapy. Examples are illustrative, not prescribing guidance.
We break each family down with more examples here: Types of targeted therapy drugs explained →
Which Cancers It Treats — Target by Target
Targeted therapy is not one treatment but dozens, each matched to a particular molecular target. It is used across lung, breast, colorectal, blood, liver, kidney, ovarian, prostate, stomach, thyroid, head and neck, and skin cancers, among others.
The right drug is chosen by the target the tumour carries, not by the organ alone.
Illustrative, not a prescribing guide. Availability, approvals and first-choice drugs differ by country and change over time. The right drug for you depends on your exact test results, stage and previous treatment.

Ask Which Applies to Me →Tumour-Agnostic Therapy: Treating the Mutation, Not the Organ
Tumour-agnostic drugs — also called histology-independent therapies — treat any cancer carrying a particular gene change, regardless of which organ it started in.
Larotrectinib and entrectinib, for example, are used against solid tumours with an NTRK gene fusion, whether that tumour is in the lung, thyroid, salivary gland or elsewhere.
This is a genuine shift in how cancer is classified. For a century, cancer was named and treated by where it started. Tumour-agnostic therapy says the driving mutation can matter more than the address.
For patients, it matters most in two situations: rare cancers with few standard options, and cancer of unknown primary, where the origin was never identified. In both, a broad molecular panel can occasionally find a target that nobody was looking for.
These drugs are still a small part of cancer treatment, and the relevant gene changes are uncommon. But if you have a rare cancer, or have run out of standard options, this is worth raising with your oncologist by name.
The Step You Can't Skip: Biomarker Testing
Before targeted therapy can begin, the tumour must be tested for a target.
This is called biomarker testing, molecular profiling or companion diagnostics, and it is done on a tissue sample — a fresh biopsy, tissue already removed at earlier surgery, or in some cases a blood sample.
If a targetable change is found, targeted therapy becomes an option; if not, your oncologist will steer you elsewhere.
Many patients do not realise this until they arrive: you cannot simply request targeted therapy. The test is what makes the plan honest, and what decides which drug — if any — will work.
Where the sample comes from. Often no new procedure is needed. If you have had a biopsy or an operation, the stored tissue can usually be tested.
Some changes can also be detected from a blood sample — sometimes called a liquid biopsy — which is useful when a tumour is hard to reach or a patient is too unwell for a biopsy.
Single-gene tests versus panels. A single-gene test asks one question, such as whether a lung cancer carries an EGFR mutation. Next-generation sequencing panels ask many questions at once across dozens or hundreds of genes.
Panels cost more but can surface options a narrow test would miss.
Why India helps here. The larger Indian cancer centres run molecular testing in-house, including next-generation sequencing.
You are not waiting weeks for a sample to travel to another country and results to travel back — which, when treatment is time-sensitive, is not a small thing.
We explain the whole process here: Biomarker testing before targeted therapy →
Already had genetic testing at home?
Send us the report — often we can plan treatment straight from it without repeating the test, which saves both time and money. A specialist reviews it free, usually within 24 hours.
Share My Test Results →When Targeted Therapy Is Not the Right Answer
Not every patient is a candidate for targeted therapy. If molecular testing finds no targetable change, there is nothing for the drug to lock onto and it will not work.
It may also be unsuitable if no approved drug exists for your target, if other illnesses make the side effects unsafe, or if a different treatment offers a better result for your stage of disease.
We include this section deliberately. A facilitator who tells you every patient is a candidate is selling, not advising — and the wrong treatment costs you time you may not have.
If targeted therapy is not right for you, that is not the end of the conversation. Chemotherapy, immunotherapy, hormone therapy, radiotherapy, surgery and clinical trials all remain on the table, alone or in combination.
A good oncologist will lay out the alternatives rather than simply closing a door.
Trials can give access to newer targeted drugs and combinations that are not otherwise available, and the trial drug is often supplied at no cost to the patient.
Eligibility is strict and trials are not right for everyone, but if standard options are limited it is a fair question to put to your oncologist directly.
How Treatment Is Actually Given
Patients take targeted therapy as tablets or capsules at home, or receive it as an intravenous infusion or an injection under the skin. Schedules vary widely: some drugs are taken every day without a break, others in cycles of treatment followed by rest.
Oral drugs often have strict instructions about food and timing that directly affect how well they work.
Oral tablets and capsules. Most small-molecule inhibitors are taken by mouth at home. This is convenient, but it shifts responsibility onto you: the schedule has to be followed exactly.
Some of these drugs must be taken on an empty stomach and others with food, because food changes how much of the drug your body absorbs. Ask your oncologist or pharmacist to write this down, and ask what to do if you vomit a dose or miss one.
Never adjust or stop the dose yourself because of side effects — call your team first.
Intravenous infusions. Many antibody-based drugs are given through a drip in a day-care unit. Patients on longer courses are sometimes given a central line or port so the drug can be delivered through the same access each time, avoiding repeated needles.
Subcutaneous injections. A growing number of targeted drugs can be given as an injection into the fatty tissue under the skin. Where this option exists it is just as effective, takes far less chair time, and avoids an IV line entirely.
Handling these drugs at home. Several targeted therapies are classed as hazardous medicines.
Your team may advise you to avoid handling tablets with bare hands, to store them separately and out of reach of children, and to take short-term precautions with body fluids after a dose. Follow the specific instructions your hospital gives you.

Get My Treatment Outline →Monitoring, Resistance and What Happens Next
While on targeted therapy you will have regular reviews with blood tests and scans to check whether the drug is working and how well you are tolerating it. Over time, many cancers develop resistance and stop responding.
This is expected rather than a failure, and it is usually followed by re-testing and a switch to a different drug or approach.
How progress is checked. Expect periodic blood tests, including liver, kidney and heart checks depending on the drug, plus CT or other imaging at intervals. Your team is watching two things at once: is the cancer responding, and is the treatment safe to continue.
Why resistance happens. Cancer cells keep mutating. Given time under pressure from a drug, some develop a workaround — a new mutation, or a different growth pathway that bypasses the blocked one. The drug that worked beautifully for a year may stop working.
What happens then. This is where modern oncology has changed the most. Rather than simply stopping, your team may re-biopsy or re-test the blood to find the new resistance mutation, then move to a next-generation drug designed for it.
In lung cancer in particular, patients often move through a sequence of targeted drugs over several years.
This is also the practical reason to keep copies of every report. When you switch treatment or change hospital or country, the molecular history of your cancer is the single most valuable document you own.
Side Effects and Warning Signs
Severe breathlessness or a new persistent cough · chest pain or a very irregular heartbeat · uncontrolled bleeding, or black tarry stools · high fever with chills.
Sudden severe abdominal pain · swelling, pain or redness in one leg · sudden confusion or severe headache · a wound that opens or will not heal.
These are not "wait and see" symptoms while on treatment. Contact your oncology team or emergency services the same day.
Targeted therapy has a different side-effect profile from chemotherapy rather than an absent one. Common effects include skin rash and dryness, diarrhoea, fatigue, raised blood pressure, mouth soreness, and changes to the hands and feet.
Less commonly, targeted drugs can affect the heart, lungs, liver, clotting and wound healing, which is why monitoring matters.
Which effects apply depends entirely on the drug. Anti-angiogenic drugs are more associated with blood pressure, bleeding and wound healing; EGFR-directed drugs with rash and diarrhoea. Your oncologist will tell you which apply to your specific regimen.
Most side effects are managed rather than endured. Dose adjustments, supportive medicines, skin care and dietary changes all help — and reporting problems early usually means a smaller intervention, not a bigger one.
If you are due to have surgery, tell every doctor involved that you are on targeted therapy. Some drugs must be paused well beforehand because of their effect on healing and bleeding.
We cover the full profile, and what to do about each, here: Targeted therapy side effects →
Targeted Therapy vs Immunotherapy
Targeted therapy attacks a fault in the cancer cell directly. Immunotherapy does not attack the cancer at all — it releases the brakes on your own immune system so that it recognises and attacks the cancer.
They are different mechanisms suited to different situations, and some patients receive both.
The line between them is blurrier than most guides admit. Some monoclonal antibodies are counted in both camps, because they hit a molecular target and recruit the immune system at the same time.
The practical difference patients notice is the side-effect pattern. Immunotherapy tends to cause immune-related inflammation that can affect almost any organ, while targeted therapy effects usually track the specific pathway being blocked.
We compare them properly here: Targeted therapy vs immunotherapy →
Why Patients Choose India
International patients choose India for targeted therapy for three reasons: cost, availability and expertise.
India manufactures many of these drugs domestically as generics and biosimilars, which lowers the price structurally, while its leading centres offer the same molecular testing and treatment protocols found in the West — without a long wait.
Cost. India produces generic versions of drugs such as imatinib and biosimilar versions of trastuzumab, rituximab and bevacizumab. When the medicine is manufactured in the same country where you are treated, the price falls sharply. This is structural, not a discount.
Availability. Drugs and molecular tests that sit behind long queues, approval delays or funding restrictions elsewhere are routinely available here, now, in accredited hospitals.
Expertise. India's leading cancer centres treat very high patient volumes, run multidisciplinary tumour boards where complex cases are discussed by a full specialist panel, and are staffed by oncologists trained in India, the UK and the US.
For families coming from the Gulf, East Africa, Bangladesh or the UK, it usually comes down to this: the same drug, the same quality of care, at a fraction of the cost, with no waiting.
For an oral targeted therapy, it can also mean starting treatment in India and continuing it at home.
What Targeted Therapy Costs in India
The cost of targeted therapy in India depends almost entirely on which drug you need and how long you take it. Generic oral drugs can start from around USD 150 a month, while newer oral agents and antibody regimens cost considerably more.
In every case the figure sits far below US or UK prices, largely because of local manufacturing.
Let's be straight about this, because vague promises help nobody. A daily generic tablet and a repeated IV antibody regimen sit at completely different price points, so a single headline "targeted therapy cost" would be misleading.
Approximate and indicative only, moving with drug choice, dose, duration and exchange rate. Your real figure only becomes meaningful once a specialist reviews your diagnosis and proposed regimen. In the US or UK, the same drugs can cost several times more.
One point international patients often miss: because targeted therapy is frequently an ongoing treatment rather than a one-off procedure, the relevant number is the monthly run rate, not just the first bill. Ask for both.

Ask Which Hospital Suits Me →Questions to Ask Before You Start
Before beginning targeted therapy, ask your oncologist what the goal of treatment is, which target was found, and on what test. Ask what the drug is expected to achieve and for how long.
Then ask what the side effects are, how the drug is taken, what it costs per month, and what the plan is if it stops working. Write the answers down.
Write the answers down.
Patients who ask these questions get better care — not because doctors treat them differently, but because the answers reveal quickly whether a plan is well thought through. Take this list to your consultation.
1. Is the goal of this treatment to cure, to control, or to relieve symptoms?
2. Which biomarker or mutation was found, and which test showed it?
3. Would a broader molecular panel change my options?
4. Is this drug used alone, or alongside chemotherapy or other treatment?
5. How is it taken, how often, and does it need to be with or without food?
6. Which side effects are likely, and which mean I should call you immediately?
7. How will we know whether it is working, and how often will I be scanned?
8. What is the plan if the cancer becomes resistant to this drug?
9. What will this cost per month, and for how long am I likely to be on it?
10. Can this treatment be continued in my home country?
11. Are there clinical trials I should consider?
Want a second opinion on a plan you've already been given?
Send us the proposed treatment plan along with your reports. An oncologist will review whether the target, the drug and the goal line up — and tell you honestly if the plan you have is already a good one.
Request a Second Opinion →How to Start Treatment With GAF
Starting is straightforward: share your reports on WhatsApp, receive an oncologist's opinion and a treatment plan with a clear cost estimate, then let GAF arrange the medical visa, travel and stay.
Because many targeted therapies are oral tablets, treatment can often continue in your home country once it is stable.
1. Share your reports. Send your diagnosis, pathology, any molecular testing and recent scans on WhatsApp. Our team reviews them.
2. Get an opinion and a plan. We arrange a review with an oncologist matched to your cancer type and return a proposed plan with a clear cost estimate — including whether targeted therapy is genuinely suitable for you.
3. Sort the practicalities. We help with your medical visa invitation letter, travel, airport pickup, accommodation near the hospital and, where relevant, language support.
4. Testing and treatment. If molecular testing is still needed, it is done first. You are then treated at an accredited hospital by a specialist matched to your cancer, with our team alongside you.
5. Continue care at home. Once treatment is stable, oral targeted therapy can often continue in your own country. We help coordinate the handover, including reports and prescriptions for your local oncologist.
Send your reports for a free, honest case review
We'll tell you whether targeted therapy fits your case, what it would realistically achieve, where it would be done and what it would cost — usually within 24 hours. If it isn't right for you, we'll say so.

Frequently Asked Questions
Is targeted therapy available in India?
Yes. India's leading accredited cancer hospitals offer the full range of targeted therapies, together with the in-house molecular testing needed to prescribe them correctly, and generally without a long waiting list.
Do I need genetic testing before targeted therapy?
Almost always. Targeted drugs only work if your cancer carries the matching target, so biomarker testing comes first. If you have already been tested at home, sharing that report may be enough to plan treatment without repeating the test.
How much does targeted therapy cost in India?
It depends on the drug and how long it is taken. Generic oral drugs can start from around USD 150 per month, while newer oral agents and antibody regimens cost more. All figures are approximate and sit far below US or UK prices, largely because of local manufacturing.
Which cancers can targeted therapy treat?
It is used across many cancers, including lung, breast, colorectal, blood cancers such as chronic myeloid leukaemia and lymphoma, ovarian, liver, kidney, melanoma, stomach, thyroid and head and neck cancers. The drug is chosen by the target the tumour carries.
Is targeted therapy better than chemotherapy?
Not automatically. It is more selective and often gentler, but it only works if a target exists, and it is not always the more effective choice. Many patients receive both. The right decision depends on your cancer's biology, which is what testing reveals.
Is targeted therapy always safer than chemotherapy?
No. It usually has milder and different side effects, but serious problems affecting the heart, lungs, liver, clotting or immune system can occur with some targeted drugs. No cancer treatment is free of risk.
What happens if targeted therapy stops working?
Cancers commonly develop resistance over time. When that happens, your oncologist may re-test the tumour or blood to identify the new mutation and switch to a next-generation drug, a different combination, or another type of treatment.
Can I continue targeted therapy after returning home?
Often, yes. Many targeted therapies are oral tablets, so once treatment is stable it can frequently continue in your home country, with GAF Healthcare helping coordinate the handover to your local oncologist.
Can targeted therapy cure cancer?
Sometimes, particularly in earlier-stage disease and usually alongside other treatments. In advanced cancer the realistic goal is more often long-term control or symptom relief. Ask your oncologist directly which goal applies to you.
