Lung Cancer Treatment
Two people can hear the same lung cancer diagnosis and end up on very different plans. The reason is usually the cancer's type and stage. Non-small cell and small cell lung cancer are treated differently, and a stage 4 plan looks nothing like one for an early tumor. Lung cancer treatment usually combines surgery, radiation, chemotherapy, immunotherapy, and targeted drugs. This page explains how the options are chosen and what to expect. Dr. Karan's view is that your plan should come from your own scans and biopsy results, not a template. Here's what most guides skip. Early-stage lung cancer can be treated with SBRT, which is just as effective as surgery, needs no incision, and causes fewer side effects. Most lung cancers are first detected at stage 4, though. Even then, molecular testing plus immunotherapy and targeted drugs can give good quality of life and disease control for 1 to 5 years.

Lung cancer treatment depends mainly on the cancer type and stage. Non-small cell lung cancer, the most common type, is often treated with surgery, radiation, immunotherapy, or targeted drugs, depending on stage. Small cell lung cancer usually responds to chemotherapy and immunotherapy, with radiation added for localized disease. Stage 1 tumors can be treated with SBRT in 3 to 5 days, with results equal to surgery and fewer side effects. Molecular testing is compulsory for every lung cancer case before treatment starts.
Dr. Karan Explains Your Treatment Options
In this short video, Dr. Karan walks through how a treatment plan is built, what each option involves, and what to expect from your first consultation.
Lung Cancer Treatments and How They Fit Together
Most lung cancers are non-small cell, about 80 to 85 percent according to the American Cancer Society. That's the majority, so most treatment decisions start there. Small cell lung cancer makes up most of the rest, and it behaves differently. It tends to grow fast and spread early, so it's usually treated with chemotherapy and immunotherapy first. For non-small cell cancer, surgery is the main option when the tumor is localized and you're fit enough for an operation.
Dr. Karan delivers the radiation. Stage 1 tumors get SBRT, a highly precise treatment completed in 3 to 5 days. Stage 2 and 3 plans use IMRT and IGRT. Chemotherapy is part of care at every stage, and it's given together with radiation in stage 3 and 4. Surgery and drug treatment are led by the surgical and medical oncologists at Apollo Hospital, Financial District. You'll always know who's doing what. The best lung cancer treatment isn't one machine or one drug. It's the plan that fits your cancer's type, stage, and biomarkers, delivered in the right order.
Lung Cancer Treatment Options
Most plans use one of these or a combination. Here's what each one does.
Surgery
Removes the tumor and nearby lymph nodes when the cancer is localized and you're fit for an operation. Often the first step for early-stage non-small cell lung cancer.
With partner thoracic surgeonsStereotactic body radiotherapy (SBRT)
Delivers high-dose radiation to a small, well-defined tumor in 3 to 5 days. For stage 1 lung cancer it's as effective as surgery, with no incision and fewer side effects.
Delivered by Dr. KaranRadiation therapy (IMRT and IGRT)
Shapes the dose to the tumor's outline and checks its position during treatment, so nearby healthy lung and heart get less. Used to plan stage 2 and 3 treatment, larger tumors, lymph node spread, and symptom relief.
Learn about IMRT →Chemotherapy
Drugs that travel through the bloodstream to reach cancer cells. Used at every stage, for small cell and non-small cell cancer. Given together with radiation in stage 3 and 4.
With partner oncologistsImmunotherapy
Helps the immune system recognize and attack cancer cells. Usually given in stage 4 and continued indefinitely. Also used in small cell lung cancer alongside chemotherapy.
With partner oncologistsTargeted therapy
Drugs aimed at specific gene changes such as EGFR or ALK, found through molecular testing. Usually given in stage 4. They only help tumors that carry one of these changes.
Discussed case by caseNot sure which lung cancer treatment fits your stage? Let's review your scans together.
Lung Cancer Treatment by Stage
The usual approach depends on whether the cancer is non-small cell or small cell, and how far it has spread.
Stage 1 and 2 non-small cell lung cancer
For stage 1, surgery is still an option if you're fit for it. SBRT is just as effective, needs no incision, and causes fewer side effects. It's finished in 3 to 5 days. Stage 2 is planned with IMRT and IGRT, and surgery stays an option there too. Chemotherapy is part of the plan at every stage, depending on the tumor.
Stage 3 non-small cell lung cancer
Usually treated with chemotherapy and radiation given together, not one after the other. Radiation is planned with IMRT and IGRT. Immunotherapy may follow for a period after chemoradiation. Surgery is considered only in selected cases after careful staging.
Stage 4 lung cancer treatment: non-small cell
Stage 4 is the stage most often detected. The cancer has spread beyond the chest, so treatment is mostly systemic. Molecular testing is compulsory before anything starts. Chemotherapy, immunotherapy, or targeted drugs are chosen by the results. Radiation is combined with chemotherapy or used to ease symptoms like bone pain or brain spread. With testing, immunotherapy, and targeted therapy, good quality of life is possible and the disease can stay controlled for 1 to 5 years.
Limited-stage small cell lung cancer
The cancer is confined to one side of the chest. Chemotherapy and radiation to the chest are usually given together, with immunotherapy added in many cases. Brain imaging and brain radiation may be discussed after the cancer responds.
Extensive-stage small cell lung cancer
The cancer has spread to the other lung, fluid around the lungs, or distant organs. Chemotherapy with immunotherapy is the core treatment and often shrinks the cancer quickly. Radiation is used selectively, mainly for symptoms or problem areas of spread.

What to Expect, Step by Step
- 01
Consultation and report review
Dr. Karan reviews your CT or PET scans, pathology, and biopsy reports, then explains the options in plain terms.
- 02
Tumor board review
Your case is reviewed at the weekly tumor board with surgical and medical oncologists. The plan is confirmed that same day and explained to you before treatment starts. It considers your physical, mental, and social health, and balances the best results against the fewest side effects.
- 03
Simulation and planning
You're fitted with a custom device and scanned, with breathing guidance since lung tumors move with each breath. The first session usually follows about 2 days after the planning scan.
- 04
Treatment sessions
SBRT for stage 1 takes 3 to 5 days. Radiation for later stages is given in short daily sessions over a few weeks. Chemotherapy and immunotherapy cycles run on the partner oncologist's schedule.
- 05
Follow-up
Regular scans track how the tumor responds and check the lungs for changes after treatment.
Side Effects and How They're Managed
Will treatment affect your breathing or energy? Often for a while, and most effects can be eased.
Worried about side effects? Dr. Karan will walk you through each one before treatment starts.
Rehabilitation and Supportive Care
Lung cancer affects breathing and energy, so the support around treatment matters just as much. Our team arranges psychological counselling, physical therapy, and breathing rehabilitation directly.
Lung Cancer Treatment Cost in India
Here's what drives lung cancer treatment cost, and how to plan for it.
Stage and treatment mix
Cost depends on the treatment. Radiation is all-inclusive. Chemotherapy is charged per session, and the number of cycles depends on your protocol. It averages ₹40,000 to ₹60,000 every 3 weeks. Immunotherapy, usually given in stage 4, costs about ₹2.5 lakh every 3 weeks and is given indefinitely. Targeted therapy runs from ₹20,000 to ₹1 lakh a month.
Sessions and planning
Radiation is all-inclusive and costs ₹2.5 to 4.5 lakh depending on the technique. SBRT needs only 3 to 5 days of treatment.
Tests and follow-up
Biopsies, molecular testing, scans, and follow-up visits add to the total. Costs also vary by hospital and city.
Many plans cover cancer care, but policies differ on pre-authorization, sub-limits, and approved drugs. Ask for a written estimate before starting.

Questions to Ask Your Oncologist
Take these to your appointment and write down the answers.
- Was my lung cancer confirmed as non-small cell or small cell?
- Have I had molecular testing for EGFR, ALK, and PD-L1?
- What is the goal of treatment: cure, control, or symptom relief?
- Which partner doctors will I see, and who coordinates them?
- What side effects should I call you about between visits?
- What does follow-up look like after treatment ends?
Questions Patients Ask Us
Surgery, radiation, chemotherapy, immunotherapy, and targeted therapy are the main options. Most patients get a combination, chosen by cancer type, stage, and biomarkers.
Non-small cell cancer often starts with surgery or radiation when localized, while small cell usually starts with chemotherapy and immunotherapy. Both can use radiation depending on how far the cancer has spread.
Stage 4 lung cancer is usually treated to control it rather than cure it, and it's the stage most often detected. With molecular testing, immunotherapy, and targeted drugs, good quality of life is possible and the disease can stay controlled for 1 to 5 years. Your oncologist can give a personal estimate based on your biomarkers and health.
Surgery is rarely the main treatment for small cell lung cancer, because it usually spreads early. It's considered only in a small number of carefully selected limited-stage cases.
Targeted therapy uses drugs that block specific gene changes such as EGFR or ALK. It only works if the tumor carries that change, so molecular testing comes first. It's compulsory for every lung cancer before treatment starts.
Common effects include tiredness, skin changes, and a cough or sore throat during treatment. Longer-term effects such as lung scarring are less common and are watched with follow-up scans.
Radiation is all-inclusive at ₹2.5 to 4.5 lakh depending on technique. Chemotherapy averages ₹40,000 to ₹60,000 every 3 weeks, immunotherapy costs about ₹2.5 lakh every 3 weeks, and targeted therapy runs ₹20,000 to ₹1 lakh a month. Ask for a written estimate once your reports are reviewed.
Yes, and many patients do. Bring your biopsy report, scans, and any molecular test results so the review is complete.
