Insight from a Lung Cancer Specialist in Lucknow
Lung Cancer – Not Just a Smoker’s Disease
Lung cancer remains the leading cause of cancer-related deaths worldwide, accounting for more fatalities than breast, prostate, and colon cancers combined. One of the biggest challenges with lung cancer is its silent progression — symptoms often do not appear until the disease has already advanced. However, the last decade has brought significant advancements in diagnosis, targeted therapies, and immunotherapy, enabling patients to live longer and with better quality of life.
Globally, lung cancer accounts for over 2.2 million new cases and approximately 1.8 million deaths annually. In India, it ranks as the number one cause of cancer death among men, with around 70,000 new diagnoses each year. Importantly, lung cancer is no longer confined to smokers. Increasingly, non-smokers — particularly women — are being diagnosed due to factors like air pollution, passive smoking, and genetic mutations.
📢 You don’t have to smoke to get lung cancer. But you must act fast to survive it.
✅ If you have a chronic cough, it’s time to consult a lung cancer specialist in Lucknow.
What Causes Lung Cancer?
Lung cancer most commonly begins in the lining of the bronchi or alveoli and develops slowly, often without early warning. The primary risk factor remains tobacco smoking, which contributes to over 80% of cases. However, passive smoking also significantly increases risk by 20–30%, especially in household and workplace environments.
In India, air pollution — particularly exposure to PM2.5 particles — has emerged as a major cause of lung cancer among non-smokers. Additional risks include radon gas exposure, occupational hazards (like asbestos or diesel fumes), a family history of lung cancer, and previous radiation therapy to the chest. Genetic mutations such as EGFR, ALK, and ROS1 are also being increasingly identified in non-smokers.
📢 Air doesn’t have to be smoked to cause lung cancer.
✅ If you live in high-pollution areas or are regularly exposed to fumes or dust, screening by a lung cancer specialist in Lucknow is strongly advised.
Symptoms of Lung Cancer
Lung cancer is often diagnosed at an advanced stage because early symptoms may be mild or mistaken for other respiratory conditions. However, there are several warning signs you should never ignore:
- Persistent cough lasting more than 3 weeks
- Coughing up blood (hemoptysis)
- Shortness of breath or wheezing
- Chest pain that worsens with breathing or coughing
- Voice changes or hoarseness
- Unexplained weight loss, fatigue, or weakness
- Recurrent episodes of pneumonia or bronchitis
- In advanced stages, symptoms such as bone pain or headaches may signal metastasis
In rare cases, lung cancer can also cause paraneoplastic syndromes, including hormonal imbalances such as high calcium levels, low sodium, or neurological symptoms.
📢 One cough that won’t go away could be your body’s alarm.
✅ Don’t ignore persistent symptoms—consult a lung cancer specialist in Lucknow for evaluation.
Diagnosis and Early Detection
Timely diagnosis is critical for improving survival rates. A chest X-ray may reveal large lung masses, but high-resolution CT scans (HRCT Thorax) are essential for accurate detection. To evaluate whether the cancer has spread, a PET-CT scan is often performed.
Bronchoscopy allows for direct visualization and biopsy of central airway tumors, while CT-guided biopsy helps sample peripheral lesions. In addition, endobronchial ultrasound (EBUS) is a minimally invasive method used to assess lymph nodes and guide treatment decisions.
Every newly diagnosed lung cancer case should undergo molecular profiling to identify driver mutations such as EGFR, ALK, ROS1, KRAS, and PD-L1 expression—which directly influence treatment options.
🩺 A lung cancer specialist in Lucknow will determine the appropriate tests to confirm diagnosis and tailor a treatment strategy.
Types and Staging of Lung Cancer
The two main types of lung cancer are:
- Non-Small Cell Lung Cancer (NSCLC): The most common type, accounting for 85% of cases. It includes:
- Adenocarcinoma (more common in non-smokers)
- Squamous Cell Carcinoma
- Large Cell Carcinoma
- Small Cell Lung Cancer (SCLC): Comprising around 15% of cases, this type is more aggressive, often spreading rapidly.
NSCLC staging ranges from:
- Stage I: Localized tumor
- Stage II: Tumor with nearby lymph node involvement
- Stage III: Regional spread within the chest
- Stage IV: Distant metastasis (lungs, bones, brain, liver)
SCLC is classified into:
- Limited-stage: Confined to one side of the chest
- Extensive-stage: Spread beyond the lungs
Treatment Options: Personalized by Type and Stage
Treatment plans depend on the cancer type, genetic mutations, stage, and patient fitness:
Early-Stage NSCLC (Stage I–II):
Surgical removal of the tumor (lobectomy or pneumonectomy) is the primary treatment. This is often followed by adjuvant chemotherapy to prevent recurrence. For patients with EGFR mutations, targeted therapy like Osimertinib may be used. Stereotactic Body Radiotherapy (SBRT) is an effective option for patients who are not surgical candidates.
Locally Advanced NSCLC (Stage III):
Patients typically receive concurrent chemotherapy and radiation therapy. For eligible patients, immunotherapy with Durvalumab for 12 months has shown survival benefits (PACIFIC trial). In select cases, chemotherapy may be given before surgery.
Advanced/Metastatic NSCLC (Stage IV):
This stage requires a personalized approach based on mutation status.
- EGFR-positive: Osimertinib
- ALK-positive: Alectinib, Lorlatinib
- ROS1, MET, RET, BRAF: Specific targeted agents available
Immunotherapy options include:
- PD-L1 ≥50%: Pembrolizumab monotherapy
- PD-L1 <50%: Combination of chemotherapy and immunotherapy (e.g., with Nivolumab, Atezolizumab)
Chemotherapy remains a key treatment, with drug choices based on cancer subtype.
For SCLC:
- Limited-stage: Combined chemotherapy (cisplatin + etoposide) and radiation
- Extensive-stage: Chemotherapy with Atezolizumab or Durvalumab (adds survival benefit)
📢 Your mutation can be your medicine.
✅ Always ask your lung cancer specialist in Lucknow about molecular and PD-L1 testing.
The Power of Targeted Therapy and Immunotherapy
Targeted therapy blocks specific proteins or mutations (like EGFR or ALK) that help cancer grow. These oral medications have fewer side effects and dramatically improve quality of life and survival — but they only work when the mutation is present.
Immunotherapy, on the other hand, activates the immune system to recognize and attack cancer cells. It is now standard in both advanced and locally advanced NSCLC. While not every patient responds, 20–30% achieve long-term remission.
✅ Molecular testing and PD-L1 profiling should be performed in all advanced cases before starting treatment.
Prevention and Screening
Though not all lung cancers are preventable, risk reduction is possible:
- Quit smoking: Lung cancer risk drops by 50% in 10 years
- Avoid passive smoking
- Reduce exposure to air pollution, workplace fumes, and radon
- Get annual low-dose CT screening if you are a high-risk adult (ages 50–80, with a history of smoking)
- Stay vaccinated against influenza and pneumonia, especially if you have chronic lung disease
Final Note: Don’t Wait to Exhale
Lung cancer may be silent, but it’s no longer unbeatable. With early diagnosis, molecular-guided therapies, and immunotherapy, survival rates are improving dramatically. Most importantly, awareness, timely screening, and expert medical guidance can save lives.
