Lung cancer can indeed be curable, especially when caught early, at Stage 1 or 2. Treatments with higher cure rates include:

• Surgery: Particularly effective for localized tumors.
• Radiation Therapy: Targets specific cancer cells.
• Targeted Therapy and Immunotherapy: Newer options showing promise in extending survival.

Early detection makes all the difference, as advanced stages tend to be more challenging. If you have concerns or symptoms, consulting Dr. Veenoo Agarwal in Delhi NCR can help you explore treatment options.

Lung cancer rates in India, particularly in urban areas like Delhi NCR, are increasing, driven by factors such as air pollution, smoking, and occupational exposures. According to the Indian Council of Medical Research (ICMR), the prevalence of lung cancer is expected to rise due to increasing urbanization and pollution levels. Key contributors include:

• Rising air pollution levels.
• Increased smoking rates, particularly among youth.
• Occupational exposures in industrial regions.

Preventive screenings and lifestyle changes can help manage risk. If you have risk factors for lung cancer, it’s essential to get regular screenings and seek medical advice.

While these cancers are different, they share some common risk factors:

• Smoking: Strongly linked to lung and bladder cancer.
• Environmental factors: Pollution, especially for lung cancer.
• Genetic predisposition: Family history can increase risk for various cancers.

For personalized risk assessments, Dr. Veenoo Agarwal provides specialized consultations.

Yes, non-smokers can also develop lung cancer, often due to:

• Air pollution, especially in high-exposure areas like Delhi NCR.
• Second-hand smoke exposure.
• Genetic mutations that make cells more prone to cancerous changes.

About 10-15% of lung cancers are diagnosed in non-smokers. Reducing exposure to these factors can help lower risk, especially in regions with high pollution levels like Delhi NCR.

Lung cancer begins when lung cells undergo mutations, leading to uncontrolled growth. This process is often triggered by:

• Smoking and carcinogen exposure.
• Genetic predisposition.
• Environmental toxins.

Early signs might include a persistent cough or chest pain, both warranting medical advice if persistent.

Exposure to asbestos is a known cause of mesothelioma, a rare cancer affecting the lining of the lungs. Asbestos exposure also increases the risk of a specific type of lung cancer called non-small cell lung cancer (NSCLC).

Lung cancer symptoms can vary in intensity and are not always constant. Common symptoms include:

• Persistent cough.
• Chest pain.
• Shortness of breath.

These symptoms may fluctuate but often persist. For any ongoing symptoms, consulting a doctor is crucial.

Lung cancer cough is often persistent, dry, and may worsen over time. Some people may also experience coughing up blood (hemoptysis). It’s different from a typical cough associated with infections and does not improve with over-the-counter treatments.

Detecting lung cancer involves multiple steps, including:

• Chest X-ray: Often the first step if symptoms are present.
• CT Scan: Provides a more detailed image.
• Biopsy: Confirms cancer through tissue analysis.
• PET-CT: Shows if cancer has spread.

For high-risk individuals, low-dose CT scans can detect lung cancer early. Dr. Veenoo Agarwal offers consultation on personalized screening options.

Lung cancer spreads when cancer cells break away from the primary tumor and travel through the bloodstream or lymphatic system to other body parts. Common areas for lung cancer metastasis include:

• Bones
• Brain
• Liver
• Adrenal glands

The spread depends on cancer type and stage. Metastatic cancer is more challenging to treat, but certain therapies can slow progression. For a comprehensive view on metastasis, see The National Cancer Institute.
