Overview
What is Lung Cancer?
- Lung cancer occurs when abnormal cells in the lungs grow uncontrollably and form a tumour
- These cells may spread to other parts of the body if not treated early
What Causes Lung Cancer?
The exact cause is not always known, but it is often linked to damage in lung cells due to:
- Smoking (most common cause)
- Exposure to second-hand smoke
- Air pollution
- Harmful chemicals (like asbestos)
Who is at Risk?
- Smoking or history of smoking
- Exposure to pollution or chemicals
- Family history of lung cancer
- Age above 50 years
- Long-term breathing problems
Symptoms of Lung Cancer
- Ongoing cough
- Coughing up blood
- Chest pain
- Shortness of breath
- Unexplained weight loss
- Constant tiredness
How is it Diagnosed?
- Chest X-ray — a basic scan to check for anything unusual in the lungs
- CT scan / PET scan — more detailed images to see the size, location, and spread
- Biopsy — taking a small piece of tissue to test for disease
- Bronchoscopy — a thin camera is passed into the lungs to look inside
How is this Condition Managed?
- Regular check-ups
- Thoracic (lung) cancer surgery
- Treatment using drugs to kill cancer cells
- Treatment using high-energy rays to destroy cancer cells
- Treatment that helps the body find and fight cancer cells more precisely
Lung Cancer Surgery
What is it?
This surgery removes the part of the lung containing the tumour while preserving as much healthy lung as possible.
Why is this Procedure Done?
A doctor may recommend surgery to:
- Remove cancer completely
- Stop the disease from spreading
- Help live longer
Types of Surgery
Open lung cancer surgery: Done using a large cut in the chest.
Thoracoscopic surgery: Uses small cuts and a camera to perform the surgery.
Robotic-assisted lung cancer surgery: Uses small cuts and robotic instruments controlled by the surgeon.
| Feature | Open | Thoracoscopy (Keyhole) | Robotic |
|---|---|---|---|
| Cut | Large | Small | Very small |
| Blood Loss | Higher | Moderate | Lower |
| Healing | Slow | Faster | Fastest |
| Precision | Low | Good | Highly precise |
| Risk of Scars | Large | Small | Low / Minimal |
Advantages of Robotic Surgery
- Less pain
- Less blood loss
- Smaller cuts
- Shorter hospital stay (3–5 days)
- Faster recovery (2–4 weeks)
Procedure Details
Instructions Before the Procedure
- Your vital signs (BP, pulse, etc.) will be checked
- Doctor will review your medicines
- Inform about allergies
- Stop smoking
- Fasting for several hours before surgery
Step-by-Step Overview
- You are given anaesthesia (put to sleep)
- Small cuts are made in the chest
- A camera and robotic instruments are inserted
- Surgeon removes the tumour using robotic control
- A chest tube helps the lung expand
Risks & Complications
Common Risks
- Pain
- Bleeding
- Infection
- Irregular heartbeat
Rare but Serious Complications
- Excess blood loss
- Blood clots
- Severe infection
- Reaction to anaesthesia
Benefits and Outcomes
Expected Results
- Removal of tumour
- Improved disease control
Success Rates
Early-stage lung cancer: about 60–80% of people survive, depending on how early it is found.
Quality of Life
- Reduced symptoms
- Improved breathing over time
- Better daily functioning
Hospital Stay & Recovery
During Hospital Stay
- Fasting on the day of procedure
- Pre-surgery preparation
- Consent and final checks
- You may have a chest tube to remove air/fluid
- Monitoring of breathing and pain
- Regular check-ups by medical team
Hospital Stay Duration
Usually around 7 days.
Recovery Timeline
- Light activity: 1–2 weeks
- Gradual improvement: 2–4 weeks
- Full recovery: 4–6 weeks
Activity Restrictions
- Avoid heavy lifting
- Avoid strenuous exercise initially
- Gradually increase activity
Follow-up Schedule
- Every 3–6 months initially
- Then yearly check-ups
Lifestyle & Prevention
Diet
- High-protein food
- Plenty of fluids
- Fruits and vegetables
Exercise
- Walking
- Breathing exercises
- Gradual increase in activity
Long-Term Care
- Regular follow-ups
- Imaging tests
- Lung function monitoring
Preventing Recurrence
- Quit smoking completely
- Avoid pollutants
- Maintain healthy lifestyle
- Follow doctor's advice
When to Contact a Doctor (Red Flags)
Contact your doctor immediately if you notice:
- Severe breathlessness
- High fever
- Heavy bleeding
- Worsening chest pain
Myths vs Facts
Only smokers get lung cancer.
Non-smokers can also develop lung cancer.
It's too late to quit smoking after a lung cancer diagnosis.
Stopping smoking can still help treatment work better and improve recovery.
Nothing can be done for advanced lung cancer.
Treatments are available that can help control the disease and improve quality of life.
Minimally invasive (robotic) thoracic surgery is less effective than open surgery.
Minimally invasive techniques, including robotic surgery, are effective and often lead to faster recovery and less pain compared to open surgery.
Frequently Asked Questions
What increases the risk of lung cancer?
Smoking is the main risk factor, but exposure to secondhand smoke, radon, air pollution, and harmful substances can also increase risk.
Who should consider lung cancer screening?
People at higher risk, especially those with a history of heavy smoking, may be eligible for lung cancer screening.
What are the benefits of minimally invasive (robotic) thoracic surgery?
It usually causes less pain, smaller cuts, and faster recovery compared to open surgery.
How is minimally invasive thoracic surgery performed?
Surgeons use small cuts and special instruments, sometimes with robotic assistance, to perform the procedure.
