Lung Cancer: Symptoms, Diagnosis & Treatment Options
Did you know? Lung cancer is the leading cause of cancer-related deaths worldwide, accounting for nearly 1 in 5 cancer deaths globally (World Health Organization, 2024). Early recognition, accurate diagnosis, and advanced treatment options can make a life-saving difference. Under the expert guidance of Dr Mathangi J, Senior Consultant & In-charge - Radiation Oncology at Gleneagles Cancer Institute, Bangalore, you are assured of the highest standards of lung cancer care, leveraging over two decades of expertise and groundbreaking radiation oncology techniques.
What Is Lung Cancer? Understanding The Basics
Lung cancer is an abnormal and uncontrolled growth of cells in the tissues of the lung. When these abnormal cells form a mass, they are often referred to as lung tumours. If left untreated, these tumours can invade surrounding tissues and spread (metastasize) to other organs, making treatment more complex.
This disease is categorized primarily into two types:
- Non-small cell lung cancer (NSCLC) – the most common type (about 85% of cases).
- Small cell lung cancer (SCLC) – a more aggressive form, accounting for about 15% of cases.
The term cancer lung is often used interchangeably with lung cancer, especially in clinical settings across India.
What Are The Early Symptoms Of Lung Cancer?
Lung cancer symptoms can be subtle or mistaken for common respiratory ailments, especially in the early stages. Recognizing these signs early can be life-saving:
- Persistent cough that worsens over time
- Coughing up blood or rust-colored sputum
- Shortness of breath or wheezing
- Chest pain that is often worse with deep breathing or coughing
- Unexplained weight loss and fatigue
- Hoarseness or change in voice
- Frequent respiratory infections (bronchitis/pneumonia)
- Swelling in the neck or face
It’s crucial to note that not all people with lung cancer experience these symptoms. Sometimes, lung tumours are detected incidentally during tests for other conditions.
How Is Lung Cancer Diagnosed?
Lung cancer diagnosis typically involves a series of clinical assessments, imaging, and laboratory tests to confirm the presence of cancer, determine its type, and stage its progression. Here’s how the process unfolds at Gleneagles Cancer Institute under the supervision of Dr Mathangi:
- Clinical Evaluation: Detailed medical history and physical examination, focusing on risk factors such as smoking, family history, and occupational exposures.
- Imaging Studies:
- Chest X-ray
- CT (Computed Tomography) scan
- PET-CT scan for whole-body evaluation
- MRI (as required)
- Sputum Cytology: Examining mucus from the lungs under a microscope for cancerous cells.
- Biopsy: Removing a small sample of lung tissue using techniques like bronchoscopy, CT-guided needle biopsy, or even surgical biopsy for definitive diagnosis.
- Laboratory Tests: Blood tests to assess overall health and organ function.
- Molecular Testing: Identifying genetic mutations (e.g., EGFR, ALK) that may influence targeted therapy choices.
The comprehensive lung cancer diagnosis process ensures the most personalized and effective lung cancer treatment plan for every patient.
What Are The Risk Factors For Lung Cancer?
Understanding risk factors enables focused screening and preventive measures. Some major risk factors include:
- Tobacco smoking: The leading cause, responsible for around 85% of all cases.
- Passive smoke exposure: Secondhand smoke increases risk.
- Exposure to carcinogens: Asbestos, radon gas, arsenic, and diesel exhaust.
- Family history: Genetic predisposition may play a role.
- Environmental pollution: Air quality is a growing concern, especially in urban India.
How Is Lung Cancer Treated? What Are The Latest Options?
Lung cancer treatment is highly individualized, based on cancer type, stage, molecular characteristics, and overall health. Dr Mathangi and her team at Gleneagles Cancer Institute bring together the latest evidence-based approaches in oncology and thoracic oncology for the best patient outcomes.
Lung cancer treatment options include:
- Surgery: Removal of the tumour or affected part of the lung (lobectomy, pneumonectomy, segmentectomy), primarily for early-stage non-small cell lung cancer.
- Radiation therapy: Advanced techniques like Stereotactic Ablative Body Radiotherapy (SBRT), Gated RapidArc, DIBH gated Radiotherapy, and Image-Guided Interstitial Brachytherapy – all available under Dr Mathangi’s expertise.
- Chemotherapy: Systemic drugs to kill cancer cells, often used in combination with radiation or surgery.
- Targeted therapy: Drugs that act on specific genetic mutations within cancer cells.
- Immunotherapy: Harnessing the body’s immune system to fight cancer more effectively.
- Palliative care: Symptom management and quality-of-life improvement for advanced cases.
Dr Mathangi’s specialization in thoracic oncology ensures that every lung cancer patient receives the most advanced, precise, and compassionate care available in South India.
