Lung Cancer

Lung Cancer Treatment in India: Symptoms, Diagnosis and Advanced Care Options

Lung cancer is a serious condition that develops when abnormal cells in the lungs grow uncontrollably and form a tumour. It can affect breathing, spread to nearby lymph nodes and, in some cases, reach other parts of the body. Understanding the early warning signs, getting an accurate diagnosis and exploring appropriate treatment options are important steps in managing the disease.

People searching for lung cancer treatment in India may have questions about cancer specialists, diagnostic tests, surgery, chemotherapy, radiation therapy and newer treatment approaches such as immunotherapy and targeted therapy. The right treatment depends on the cancer type, stage, molecular characteristics, general health and individual treatment goals.

Siris Healthcare helps patients and families explore relevant hospitals, medical specialists and treatment options across India. Through our healthcare network, patients can research lung cancer hospitals, thoracic oncology specialists and cancer treatment services to make more informed decisions about their care.

Understanding Lung Cancer and Its Different Types

Lung cancer begins when cells in the lung tissue develop abnormal changes and multiply without normal control. These cancer cells may form a mass, interfere with lung function or spread to other organs through the blood or lymphatic system.

The two major categories of lung cancer are non-small cell lung cancer and small cell lung cancer. Identifying the correct type is essential because each can behave differently and may require a different treatment strategy.

Non-Small Cell Lung Cancer (NSCLC)

Non-small cell lung cancer (NSCLC) is the most common category of lung cancer. It includes several subtypes:

• Adenocarcinoma: Often develops in the outer regions of the lungs and is one of the most frequently diagnosed forms of lung cancer.
• Squamous cell carcinoma: Usually develops in the cells lining the airways and is associated with tobacco exposure.
• Large cell carcinoma: A less common type that can develop in different parts of the lung.

Treatment may involve surgery, chemotherapy, radiation therapy, immunotherapy or targeted therapy, depending on the tumour's characteristics and stage.

Small Cell Lung Cancer (SCLC)

Small cell lung cancer is a less common type that often grows and spreads more rapidly than NSCLC. It is strongly associated with smoking history.

Treatment commonly involves systemic therapies such as chemotherapy and, for selected patients, immunotherapy and radiation therapy. The treatment plan depends on the extent of the disease and the patient's overall condition.

Common Lung Cancer Symptoms and Early Warning Signs

Recognising possible lung cancer symptoms can help people seek medical evaluation without unnecessary delay. Some patients may not experience noticeable symptoms during the early stages, which is one reason the disease can sometimes be diagnosed later.

Common signs and symptoms include:

• A persistent cough that does not improve or gradually becomes worse.
• Coughing up blood or blood-stained sputum.
• Chest pain or discomfort, particularly when coughing or breathing deeply.
• Shortness of breath or difficulty breathing.
• Wheezing or changes in normal breathing patterns.
• Repeated chest infections, including pneumonia.
• Persistent tiredness or unexplained fatigue.
• Unintentional weight loss or reduced appetite.
• A hoarse voice that does not improve.

These symptoms do not automatically indicate lung cancer. Respiratory infections, chronic lung conditions and other medical problems can cause similar symptoms. However, persistent or unexplained changes should be assessed by a qualified healthcare professional.

Coughing up blood or experiencing significant breathing difficulty requires prompt medical attention.

What Causes Lung Cancer? Risk Factors to Understand

Lung cancer can develop due to a combination of environmental exposures, lifestyle factors and biological changes. Smoking is the most established risk factor, but people who have never smoked can also develop the disease.

Important risk factors include:

Tobacco Smoking and Secondhand Smoke

Cigarette smoking is a major cause of lung cancer. Exposure to secondhand tobacco smoke can also increase risk. The risk is influenced by the duration and intensity of exposure.

Air Pollution

Long-term exposure to outdoor air pollution, including fine particulate matter, is associated with an increased risk of lung cancer.

Occupational Exposure

Certain workplace substances, including asbestos, silica, diesel exhaust and other hazardous materials, may increase lung cancer risk, particularly with prolonged exposure.

Radon and Other Environmental Exposures

Radon is a naturally occurring radioactive gas that can accumulate in enclosed spaces. Long-term exposure can increase lung cancer risk.

Family History and Previous Medical History

A family history of lung cancer and certain previous lung conditions may be relevant when assessing an individual's overall risk.

Not everyone with these risk factors develops lung cancer, and the disease can occur in people without an identifiable exposure history.

Lung Cancer Diagnosis: Tests and Medical Evaluation

An accurate lung cancer diagnosis involves identifying whether cancer is present, determining its specific type and assessing how far it has spread. Doctors select investigations according to symptoms, examination findings and previous medical history.

Common diagnostic investigations include:

Chest X-Ray and CT Scan

A chest X-ray may help identify an abnormal area in the lungs. A CT scan provides more detailed images and can help doctors evaluate the size, position and characteristics of a suspected tumour.

PET-CT Scan

A PET-CT scan may be recommended to assess metabolic activity and investigate whether cancer has spread to other parts of the body.

Bronchoscopy

Bronchoscopy allows a specialist to examine the airways using a thin, flexible instrument with a camera. It may also help collect tissue or fluid samples for further testing.

Lung Biopsy and Pathology Examination

A biopsy involves collecting a small tissue sample from a suspicious area. A pathologist examines the sample to determine whether cancer cells are present and identify the cancer subtype.

Molecular and Biomarker Testing

For selected lung cancers, molecular testing can identify specific genetic changes or biomarkers within tumour cells. These findings may help doctors determine whether targeted therapy or certain immunotherapy treatments are appropriate.

Lung Function Assessment

Pulmonary function tests measure how effectively the lungs work. They may be particularly important when doctors are evaluating a patient's suitability for lung cancer surgery.

Lung Cancer Stages and Why They Matter

Lung cancer staging describes the extent of cancer in the body. It helps doctors understand the size of the tumour, whether nearby lymph nodes are affected and whether the disease has spread to distant organs.

For non-small cell lung cancer, staging generally ranges from Stage I to Stage IV, with additional subdivisions.

• Stage I: Cancer is limited to the lung and has not spread to nearby lymph nodes.
• Stage II: Cancer may involve nearby structures or lymph nodes within the lung region.
• Stage III: Cancer may involve more extensive nearby structures or lymph nodes within the chest.
• Stage IV: Cancer has spread to distant parts of the body or involves extensive disease within the chest.

Small cell lung cancer is also commonly described as limited-stage or extensive-stage disease.

Staging systems differ between lung cancer types. The final stage is determined using appropriate imaging, biopsy findings and other clinical assessments. Treatment decisions should never be based on symptoms alone.

Lung Cancer Treatment Options in India

Lung cancer treatment has several approaches, and not every patient requires the same combination of therapies. Treatment planning considers the cancer subtype, stage, molecular findings, overall health and the patient's preferences.

A multidisciplinary team may include medical oncologists, thoracic surgeons, radiation oncologists, pulmonologists, radiologists and pathologists.

Lung Cancer Surgery

Lung cancer surgery may be recommended for selected patients, particularly when the tumour can be removed safely and the disease is suitable for an operation.

Common surgical procedures include:

• Lobectomy: Removal of the affected lobe of the lung.
• Segmentectomy: Removal of a smaller anatomical section of the lung.
• Wedge resection: Removal of the tumour along with a small surrounding portion of lung tissue.
• Pneumonectomy: Removal of an entire lung in selected cases.

Minimally invasive approaches, including video-assisted thoracoscopic surgery (VATS) and robotic-assisted thoracic surgery, may be considered when clinically appropriate.

Chemotherapy for Lung Cancer

Lung cancer chemotherapy uses medicines to destroy cancer cells or slow their growth. It may be recommended before surgery, after surgery, alongside radiation therapy or as part of treatment for advanced disease.

The medicines, number of treatment cycles and schedule depend on the cancer type, stage, previous treatments and the patient's health.

Read more about chemotherapy treatment and cancer care.

Radiation Therapy for Lung Cancer

Radiation therapy, also called radiotherapy, uses carefully planned radiation to damage cancer cells and control tumour growth.

It may be used as the main treatment for selected patients, after surgery, alongside chemotherapy or to relieve symptoms caused by advanced cancer.

The radiation technique and treatment schedule depend on the tumour's location, stage and treatment goals.

Learn about radiation therapy and radiotherapy.

Immunotherapy for Lung Cancer

Lung cancer immunotherapy uses medicines that help the immune system recognise and respond to cancer cells.

Certain immunotherapy medicines may be recommended for selected patients with NSCLC or SCLC. The decision depends on the cancer type, stage, biomarker results, previous treatment and overall health.

Immunotherapy can cause immune-related side effects, so patients require appropriate clinical monitoring throughout treatment.

Explore cancer immunotherapy treatment.

Targeted Therapy for Lung Cancer

Targeted therapy for lung cancer focuses on specific molecular changes that help cancer cells grow or survive.

Some patients with NSCLC may have alterations involving genes such as EGFR, ALK, ROS1, BRAF, MET, RET, NTRK or KRAS. When appropriate testing identifies an actionable alteration, a specialist may consider a medicine designed to target it.

Not every lung cancer has an actionable mutation. Molecular testing is important before selecting this type of treatment.

Combined Treatment for Advanced Lung Cancer

Some patients require more than one treatment method. Depending on the diagnosis, doctors may recommend combinations of chemotherapy, immunotherapy, targeted therapy and radiation.

For selected patients, treatment may focus on controlling disease progression, managing symptoms and maintaining quality of life.

Patients can explore combined chemotherapy and immunotherapy options to understand available care pathways.

What to Expect Before and After Lung Cancer Treatment

Preparing for lung cancer treatment involves more than completing diagnostic tests. Patients should understand the proposed treatment, expected schedule, possible side effects and follow-up requirements.

Preparing for Treatment

Before starting treatment, doctors may review:

• Biopsy and pathology reports.
• CT, PET-CT and other imaging results.
• Molecular and biomarker test results, when applicable.
• Previous medical and surgical history.
• Current medicines and allergies.
• Lung and heart function, when required.
• Nutritional status and general physical condition.

Patients should bring previous investigation reports and a list of current medications to their consultations.

Recovery After Lung Cancer Surgery

Recovery depends on the surgical procedure, the amount of lung tissue removed and the patient's overall health.

After surgery, care may include pain management, breathing exercises, gradual mobilisation, nutritional support and pulmonary rehabilitation when recommended.

Some patients may require additional chemotherapy, radiation or other treatment after surgery, depending on the final pathology findings.

Managing Treatment Side Effects

Treatment-related side effects vary depending on the medicines and procedures used. Patients may experience fatigue, nausea, appetite changes, skin reactions, breathing discomfort or other symptoms.

Patients should inform their medical team about new or worsening symptoms rather than changing or stopping prescribed treatment independently.
