Lung Cancer क्यों Dangerous है?
भारत में lung cancer एक silent killer है।
क्या आप जानते हैं?
भारत में हर साल 70,000+ लोगों को lung cancer का diagnosis होता है
80% cases late stage में पकड़े जाते हैं
5-year survival rate केवल 15-20% है (अगर late detection हो)
लेकिन यहाँ अच्छी खबर है:
अगर early stage में diagnosis हो, तो 5-year survival rate 50-60% तक बढ़ सकता है
Early stage cancers को surgery से ठीक भी किया जा सकता है
आजकल की modern treatments से quality of life भी अच्छी रहती है
क्यों Lung Cancer को Late में Diagnose किया जाता है?
1. Symptoms को कम महत्व दिया जाता है
क्या लोग सोचते हैं:
- “बस एक cough है, ठीक हो जाएगी”
- “सभी को कभी न कभी cough आती है”
- “डॉक्टर को दिखाना बेकार है”
- “पुरानी खांसी है, कुछ गंभीर नहीं होगा”
Reality:
- 2-3 हफ़्तों की खांसी हमेशा normal नहीं होती
- Persistent symptoms serious हो सकते हैं
- Early doctor visit = early detection
2. Lung Cancer का Misconception
गलत धारणा:
- Only smokers को lung cancer होता है
- अगर मैं non-smoker हूँ तो safe हूँ
- Young people को lung cancer नहीं होता
सच:
- 15-20% lung cancer non-smokers में होती है
- Air pollution, genetics, occupational exposure भी कारण हैं
- किसी भी age में हो सकता है
3. Early Lung Cancer का No Obvious Symptoms
बहुत early stages में:
- कोई symptoms नहीं होते
- या बहुत mild symptoms हों
- People आमतौर पर ignore कर देते हैं
Lung Cancer क्या है?
Normal vs Cancer Cells:
हमारे फेफड़ों में लाखों cells होती हैं। ये cells controlled तरीके से काम करती हैं:
- Oxygen ले जाती हैं
- Carbon dioxide निकालती हैं
- वक़्त आने पर मर जाती हैं
लेकिन कभी-कभी कुछ cells abnormal हो जाती हैं:
- बिना किसी नियंत्रण के divide करने लगती हैं
- एक-दूसरे को stack करके tumor बन जाती हैं
- यह tumor nearby tissues में फैलने लगता है
- कभी-कभी दूसरे organs में भी फैल जाता है (metastasis)
यही है – LUNG CANCER (फेफड़ों का कैंसर)
Types of Lung Cancer:
1. Non-Small Cell Lung Cancer (NSCLC) – 85% cases
Sub-types:
A. Adenocarcinoma (40-50% of all lung cancers)
- Location: Lungs के outer portions में
- Who gets: Often non-smokers, young people, women
- Growth: Relatively slow
- Prognosis: Better than other types
B. Squamous Cell Carcinoma (25-30%)
- Location: Central airways (main bronchi)
- Who gets: Usually smokers
- Growth: Moderate speed
- Characteristics: Can block air passages
C. Large Cell Carcinoma (10-15%)
- Location: Any part of lung
- Who gets: Usually smokers
- Growth: Fast
- Prognosis: Poorest among NSCLCs
2. Small Cell Lung Cancer (SCLC) – 15% cases
Characteristics:
- Growth: Very fast, aggressive
- Spread: Spreads quickly to other organs
- Who gets: Almost always smokers
- Stage at diagnosis: Usually advanced
- Treatment: Chemotherapy + radiation often recommended
Note: “Small cell” = microscopic size, not severity. Actually सबसे aggressive है।
Lung Cancer का Spread (Metastasis):
Lung cancer आमतौर पर फैलता है:
| Location | Symptoms |
| Brain | Headaches, dizziness, confusion, seizures |
| Bones | Bone pain (especially back, ribs) |
| Liver | Jaundice, abdominal pain, fatigue |
| Adrenal glands | Hormonal imbalances, weakness |
| Lymph nodes | Swelling in chest, neck, armpits |
Important: Metastatic lung cancer treatment ज़्यादा challenging होता है।
Lung Cancer के Early Symptoms
“अगर कोई भी निम्नलिखित symptom 2-3 हफ़्तों से ज़्यादा है, तो तुरंत doctor को दिखाएं।”
1: Persistent Cough (लगातार खांसी) – Most Common
यह कैसी होती है?
- Duration: 2-3 weeks से ज़्यादा (या constant रहती है)
- Pattern: Comes and goes (intermittent) या lasts all day
- Response to medicines: Normal cough syrups से relief नहीं मिलता
- Associated: साथ में कभी mucus, कभी dry
- Worse timing: अक्सर सुबह या रात को ज़्यादा severe
कैसे Different है Normal Cough से?
| Feature | Normal Cough | Concerning Cough |
| Duration | Few days – 1 week | 2-3 weeks+ |
| Causes | Cold, flu, infection | No obvious cause |
| Response | Medicines से ठीक हो जाती है | Medicines से relief नहीं |
| Associated | Fever, cold symptoms | No fever |
| Behavior | Comes and goes | Persistent, regular |
Why it is dangerous?
जब lung cancer grow कर रहा होता है:
- Tumor airways को irritate करता है – cough
- Airway को block करने लगता है – persistent cough
- Mucus production increase – productive cough
क्या करें?
अगर cough है तो:
- Track कीजिए: कितने दिनों की है?
- Note करिए: क्या pattern है? (continuous या intermittent)
- Observe करिए: कोई improvement हुई medicines से?
- Doctor दिखाइए: अगर 2-3 weeks हो गई
Important: “Just a cough” न मानें। कभी-कभी “just a cough” ही cancer होता है।
2: Hemoptysis – Blood in Cough (खांसी में खून आना)
यह कितना Serious है?
यह एक ALERT SIGNAL है। जब भी खांसी में खून आए, तुरंत doctor को दिखाएं।
क्यों होता है?
Tumor के कारण:
- Tumor blood vessels को damage करता है
- Blood vessels से खून रिसने लगता है
- खांसी के दौरान यह खून निकल आता है
Amount:
- कभी बहुत thoda (streaking)
- कभी ज़्यादा (frank bleeding)
- दोनों ही concerning हैं
कैसे Differentiate करें?
Blood in sputum vs दूसरी conditions:
| Condition | Blood Characteristics |
| Lung Cancer | Bright red, mixed with sputum, persistent |
| Bronchitis | Can occur, but usually transient |
| TB | Thick, bloody sputum, weight loss |
| Pneumonia | Rusty sputum, fever present |
| Gum disease | Only when spitting, no internal bleeding |
क्या करें?
IMMEDIATE ACTION:
- Doctor को same day दिखाएं
- Emergency room जाएं अगर heavy bleeding हो
- Don’t wait for other symptoms
3: Shortness of Breath (सांस लेने में दिक्कत)
यह कैसा Feel होता है?
- साधारण काम में भी सांस फूलना (walking, climbing stairs)
- Resting में भी breathlessness (advanced cases)
- कभी-कभी chest tightness के साथ
- पहले ऐसा नहीं था (sudden change)
क्यों होता है?
Lung cancer के कारण:
- Tumor airway को narrow करता है – कम oxygen जा सकता है
- Fluid accumulate होता है around lungs (pleural effusion) – lung compress होते हैं
- Breathing muscles को affect करता है
Severity Levels:
Mild:
- Normal daily activities में breathlessness
- Light exercise से थक जाना
- Rest से recover हो जाता है
Moderate:
- Resting state में भी feel होता है
- Walking में limitation आ जाती है
- Climbing stairs impossible हो सकते हैं
Severe:
- Talking में भी breathless
- Resting में भी sore
- Emergency situation
क्या करें?
Mild breathlessness:
- Doctor को अगले हफ़्ते दिखाएं
- Observe करिए pattern
Moderate-to-Severe:
- Urgent doctor visit
- अगर साथ में chest pain हो तो emergency
4: Chest Pain (सीने में दर्द)
किस तरह का Pain होता है?
- Location: Chest का specific area (often side)
- Nature: Constant, dull ache या sharp pain
- Triggered: Deep breathing, coughing से बढ़ता है
- Duration: Persistent (आता-जाता नहीं)
- Worse: Lying flat position में
क्यों होता है?
जब tumor involve करता है:
- Chest wall को invade करता है – direct pain
- Pleura को irritate करता है (lungs के around membrane) – pain with breathing
- Rib को affect करता है – bone pain
Important Distinction:
Lung Cancer का chest pain vs Heart pain:
| Feature | Lung Cancer Pain | Heart Pain |
| Location | Specific area, one side | Center, radiates to arm |
| Trigger | Breathing, coughing | Exertion, stress |
| Associated | Cough, breathing issues | Palpitation, sweating |
| Relief | Rest help नहीं करता | Rest से relief |
Note: अगर doubt हो तो doctor से check करवाएं।
5: Hoarseness या Voice Change (आवाज़ बैठ जाना)
क्या होता है?
- आवाज़ भारी या groggy हो जाती है
- रातों-रात change नहीं होता (gradually)
- लगातार 2-3 weeks से रहता है
- बेहतरी नहीं होती हफ़्तों बाद
क्यों होता है?
Laryngeal nerve involvement:
- Lung tumor recurrent laryngeal nerve को damage करता है
- यह nerve vocal cords को control करती है
- Nerve damage से voice change
Important: Hoarseness usually smoking से, infection से, या allergy से भी होता है। लेकिन अगर persistent हो तो check करवाएं।
क्या करें?
अगर hoarseness है:
- Duration track करिए (कितने दिनों की है?)
- Associated symptoms note करिए
- 2+ weeks हो तो doctor दिखाएं
6: Sudden Weight Loss (बिना वजह वजन कम होना)
क्यों होता है?
- Tumor increased metabolism
- Appetite suppression – food attractive नहीं लगता
- Nutrient absorption में problem आती है
- Cachexia (cancer की वजह से body tissues loss)
Important Markers:
| Amount | Timing | Concern |
| 5-10% body weight | 1-2 months | Moderate |
| 10-15% body weight | 1-2 months | High |
| 15%+ body weight | 1-2 months | Very High |
Example: अगर आप 60 kg हैं और 6 kg खो गई 2 months में = 10% = concerning
Associated Symptoms:
अगर weight loss साथ में आए:
- Loss of appetite
- Early fullness (थोड़े में पेट भर जाना)
- Taste changes
- Fatigue
तो doctor visit urgent है।
क्या करें?
Weight loss को seriously लीजिए:
- Track करिए: हर महीने वजन check करिए
- Calculate करिए: कितने % weight loss है?
- Duration नोट करिए: कितनी जल्दी हुआ?
- Doctor दिखाइए: अगर 5%+ हो
7: Persistent Fatigue (लगातार थकान)
क्या होता है?
- सदा थका हुआ feel करना even after adequate sleep
- सुबह ही tired feel होना
- Daily activities में effort लगती है
- रातभर सोने के बाद भी energy नहीं
क्यों होता है?
Cancer से related:
- Tumor increased energy demands करता है
- Anemia (low hemoglobin) से fatigue
- Cytokines release (inflammatory markers)
- Poor nutrition absorption
Severity Assessment:
Mild: Activities possible, but tiring Moderate: Activities में limitation Severe: Basic activities भी difficult
क्या करें?
Fatigue को track करिए:
- कब शुरू हुई?
- क्या improving है या worsening?
- दूसरे symptoms साथ में हैं?
- Sleep अच्छी हो रही है?
अगर 2-3 weeks से bunk्ष्टिna fatigue हो तो doctor दिखाएं।
8: Frequent Respiratory Infections (बार-बार संक्रमण)
क्या होता है?
Pattern:
- Recurrent pneumonia – same location में बार-बार
- Chronic bronchitis – long-lasting inflammation
- Repeated chest infections – जो normal नहीं होते
- Treatment resistant infections – antibiotics से भी ठीक नहीं होते
क्यों होता है?
Tumor के कारण:
- Local airway obstruction – air doesn’t clear properly
- Impaired immune response – cancer suppresses immunity
- Post-obstructive pneumonia – tumor के बाद infection
- Reduced lung capacity – proper ventilation नहीं
Red Flag Pattern:
अगर आप normal हो, फिर अचानक:
– एक महीने में 2+ respiratory infections
– Same location में बार-बार pneumonia
– Antibiotics से ठीक नहीं हो रहे
– Imaging में “consolidation” same area में persistent
→ यह concerning है, investigate करवाना चाहिए
क्या करें?
अगर pattern दिख रहा है:
- Imaging (X-ray) में क्या है यह check करवाएं
- Same area में बार-बार infection = investigate करवाएं
- Pulmonary specialist को दिखाएं
9: Wheezing (खीझ-खीझ की आवाज़)
क्या होता है?
- हल्की whistling sound जब सांस लेते हो
- Breathing के दौरान audible हो सकता है
- One-sided (एक तरफ से ज़्यादा)
क्यों होता है?
Tumor के कारण:
- Airway partial blockage – air squeeze करके निकलती है
- Inflammation – airways को swell करती है
Important Distinction:
Wheezing के कारण:
- Asthma (most common)
- Allergies
- COPD
- Bronchitis
- Lung cancer (rare but possible)
Differentiating point:
- Asthma में usually bilateral (दोनों तरफ)
- Lung cancer में usually unilateral (एक तरफ)
क्या करें?
अगर नई wheezing है:
- Doctor check करवाएं
- One-sided या both-sided = note करिए
- X-ray करवाएं
Advanced/Metastatic Lung Cancer Symptoms
जब cancer फैल चुका हो:
Brain Metastasis (30% of advanced cases):
- Persistent headaches
- Dizziness, vertigo
- Confusion, memory problems
- Seizures
- Nausea without reason
Action: Neurological examination + brain imaging (MRI)
Bone Metastasis (30% of cases):
- Bone pain (especially back, ribs)
- Muscle weakness
- Inability to move certain limbs
- Spinal cord compression (emergency)
Action: Bone imaging + oncology consultation
Liver Metastasis (20% of cases):
- Jaundice (yellowish skin/eyes)
- Abdominal pain
- Abdominal distension
- Loss of appetite
Action: Liver function tests + imaging
Adrenal Metastasis:
- Unexplained anxiety
- Weakness, fatigue
- Low blood pressure symptoms
Action: Hormonal testing + imaging
Lung Cancer के Risk Factors – किन्हें खतरा है?
1: Smoking (धूम्रपान) – Biggest Risk
How Much Risk?
| Smoking Status | Relative Risk |
| Non-smoker | 1x (baseline) |
| Former smoker (quit 15+ years ago) | 4x |
| Former smoker (quit <15 years ago) | 8-15x |
| Current smoker | 15-25x |
| Heavy smoker (pack-years) | 25-50x |
Pack-years calculation: (Cigarettes/day ÷ 20) × Years of smoking
- Example: 1 pack/day × 30 years = 30 pack-years
कैसे smoking से cancer होता है:
- Toxic chemicals: Tobacco में 4,000+ chemicals, 70+ carcinogens
- Direct damage: Chemicals lungs की cells को damage करते हैं
- Repeated injury: Years of exposure से cancer develop होता है
- Impaired immunity: Smoking immune system को weaken करती है
Types of Smoking Risk:
Active Smoking:
- Direct lung exposure
- Highest risk
Passive Smoking:
- Secondhand smoke breathing
- 15-30% increased risk
Smokeless Tobacco:
- Mouth/throat cancer ज़्यादा
- Lung cancer risk भी है
2: Air Pollution (वायु प्रदूषण)
PM2.5 और Lungs:
What is PM2.5?
- Fine particulate matter (< 2.5 micrometers)
- Car emissions, industrial smoke, dust
- भारत में कई cities में very high levels
Impact:
- Chronic inflammation in lungs
- DNA damage to lung cells
- Increased cancer risk 10-20% in high pollution areas
Geographic Risk:
High-risk areas in India:
- Delhi, NCR region (AQI often > 300)
- Industrial areas (steel plants, refineries)
- Traffic-heavy cities
- Brick kilns areas
Risk Amount:
- Living in high-pollution area × 20+ years = significant cancer risk
What You Can Do:
Pollution reduction:
- Air purifier use करिए (घर में)
- Mask पहनिए (N95, high pollution days में)
- Outdoor activities reduce करिए (high AQI days)
- Trees लगवाइए (air quality improve के लिए)
3: Family History (वंशानुगत)
Genetic Component:
BRCA, TP53, EGFR mutations:
- कुछ genes hereditary lung cancer से linked हैं
- Family members में cancer होने से risk बढ़ता है
Risk Pattern:
One family member with lung cancer:
- Risk 1.5-2x increase
Multiple family members:
- Risk 3-5x increase
Young age at diagnosis (< 50 years):
- Suggests genetic component
- Siblings को screening recommend
4: Occupational Exposure (व्यावसायिक जोखिम)
High-Risk Occupations:
| Occupation | Carcinogen | Risk Level |
| Mining | Radon, asbestos, silica | Very High |
| Welding | Metal fumes, asbestos | High |
| Construction | Asbestos, silica dust | High |
| Painting | Paint fumes, solvents | Moderate-High |
| Factory work | Various chemicals | High |
| Firefighting | Smoke, toxic fumes | High |
| Foundry work | Metal dust, chemicals | High |
Asbestos Exposure:
Specific risk factor:
- Old buildings में use होती थी
- Insulation, tiles, pipes में
- Exposure 20-50 साल बाद cancer
Mesothelioma specifically:
- Asbestos से related
- Very aggressive
- Treatment difficult
5: Radon Exposure (रेडॉन गैस)
What is Radon?
Naturally occurring radioactive gas:
- Ground से निकलती है
- Buildings में accumulate हो सकती है
- Colorless, odorless (detection के लिए testing needed)
In India:
- Some areas में levels high हो सकते हैं
- Basements में higher concentration
Risk:
- Long-term exposure from radon = lung cancer
- Combined with smoking = synergistic risk
6: Previous Lung Disease
Conditions That Increase Risk:
COPD (Chronic Obstructive Pulmonary Disease):
- 4-6x increased risk
- Even after smoking cessation
Idiopathic Pulmonary Fibrosis (IPF):
- 7-10x increased risk
- Progressive scarring की वजह से
TB (Tuberculosis):
- Previous TB = 2-3x increased risk
- Scarring और chronic inflammation
Asthma:
- Moderate increase (less than COPD)
- Chronic inflammation involved
Lung Cancer Screening – Early Detection के तरीके
Who Should Be Screened?
Recommended Screening (High-risk people):
LDCT Screening Candidates:
- Age 55-74 years

- Can detect distant metastases
- Helps treatment planning
Limitations:
- Expensive (₹20,000-40,000)
- Radiation exposure
- Mainly for diagnosis confirmation, not screening
5. Bronchoscopy
What it is:
- Flexible tube through mouth/nose
- Direct visualization of airways
- Tissue biopsy possible
Advantages:
- Can see central lesions
- Biopsy possible
- Therapeutic too (remove blockages)
Limitations:
- Invasive procedure
- Mainly diagnostic/therapeutic, not screening
- Skill-dependent
When to Get Screened?
For High-Risk (Smokers):
- Annual LDCT recommended
- Age 55-74 years
- 30+ pack-year history
For Former Smokers:
- If quit <15 years ago AND high pack-years
- Annual screening advised

Symptoms से Diagnosis तक – Timeline
Typical Patient Journey:
Week 1-2:
Patient cough को ignore करते हैं
“बस एक cough है, ठीक हो जाएगी”
Week 3-4:
Persistent symptoms महसूस होते हैं
अब doctor को phone करते हैं
Appointment 1-2 weeks बाद
Week 5-6:
First doctor visit
Clinical examination
X-ray ordered
अगर suspicious: CT scan reference
Week 6-8:
CT scan done
Results: “Nodule found”
या “Consolidation”
या “Mass”
अगर suspicious:
– PET-CT ordered
– Biopsy appointment given
Week 8-12:
Biopsy done
Tissue sent to pathology
Results: 1-2 weeks
Week 12-14:
Pathology report ready
Diagnosis: Lung cancer confirmed
Staging complete
Treatment planning starts
Total time: 12-14 weeks (3+ months)
अगर सब कुछ fast track हो:
- Can be 4-6 weeks
Important: Early detection से time to diagnosis कम होता है।

Lung Cancer में Differential Diagnosis
जब symptoms हों, doctor को दूसरी diseases भी rule out करनी पड़ती हैं:
| Disease | Key Differences | How It Differs |
| COPD/Bronchitis | Reversible, responds to treatment | Improves with treatment |
| TB | Constitutional symptoms (fever, night sweats) | Weight loss, chronic cough |
| Pneumonia | Acute onset, fever, productive | Responds to antibiotics |
| Asthma | Reversible, wheezing bilateral | Responds to inhalers |
| Sarcoidosis | Other systemic symptoms | Non-neoplastic granulomas |
| Pulmonary Embolism | Acute, PE risk factors | Normal chest X-ray |
Frequently Asked Questions
Q1: क्या हर cough lung cancer है?
A: नहीं, लेकिन:
- Most coughs viral हैं (cold, flu)
- Usually 1-2 weeks में ठीक हो जाती हैं
- अगर 2-3 weeks से ज़्यादा है तो check करवाएं
- Persistent cough में 1-5% में lung cancer होती है
Reality: नहीं, सभी persistent cough = cancer नहीं। लेकिन कुछ cases में होता है, इसलिए check करवाएं।
Q2: Non-smokers को lung cancer हो सकता है?
A: हां, 15-20% lung cancers non-smokers में होती हैं।
Reasons:
- Air pollution
- Secondhand smoke
- Radon exposure
- Occupational exposure
- Genetic predisposition
- Previous lung disease
Example: एक महिला, non-smoker, living in Delhi (high pollution) को lung cancer हो सकता है।
Q3: अगर symptoms हों तो कितनी जल्दी doctor दिखाएं?
- Blood in sputum: TODAY (same day)
- Persistent cough: Within 1-2 weeks
- Shortness of breath: Within 1 week
- Weight loss: Within 2 weeks
Rule: “अगर symptoms 2+ weeks हो तो delay न करें”
Q4: Early detection से क्या फरक पड़ता है?
| Stage | 5-Year Survival |
| Stage 1 | 50-70% |
| Stage 2 | 30-50% |
| Stage 3 | 15-30% |
| Stage 4 | 5-10% |
Difference: 60% से आ जाता है 5% तक। यह massive difference है।
Q5: CT scan safe है lung cancer screening के लिए?
A: Yes, LDCT (Low-Dose CT) safe है:
- Radiation dose बहुत कम (smoking के cancer risk के मुकाबले negligible)
- Annual screening में risk-benefit favorable है
- No alternative better है screening के लिए
But: Unnecessary CTs avoid करने चाहिए (radiation एक्यूमुलेट हो सकता है)
Q6: Varanasi में lung cancer screening कहां करवा सकते हैं?
A: Dr. Neha Gupta की clinic में:
- Complete diagnostic imaging
- CT scan facility
- Expert assessment
- Treatment planning
- Follow-up care

Lung Cancer Prevention – Risk को Reduce करें
अगर Smoker हो:
1. QUIT SMOKING
- सबसे effective prevention
- Quit करने के बाद भी risk रहता है लेकिन significantly reduce होता है
- 10-15 साल बाद risk 50% तक कम हो जाता है
How to Quit:
- Professional help लें
- Nicotine replacement therapy
- Behavioral support
- Medications (varenicline, bupropion)
अगर Non-Smoker हो:
1. Air Pollution Reduction
- Air purifier घर में लगवाएं

- Outdoor exposure reduce करिए (AQI > 200)
2. Occupational Safety
- Protective equipment use करिए (if exposed)
- Proper ventilation ensure करिए
- Regular health screening
3. Radon Testing
- अगर basement है तो radon test करवाएं
- अगर high हो तो ventilation improve करिए
4. Genetic Counseling
- Family history हो तो genetic counselor दिखाएं
- BRCA, TP53 mutations के लिए testing
- Preventive screening schedule plan करिए
सभी को:
1. Healthy Lifestyle
- Regular exercise
- Healthy diet (fruits, vegetables)
- Adequate sleep
- Stress management
2. Regular Health Checkups
- Annual screening अगर risk factors हों
- Doctor से discuss करिए personal risk
3. Early Symptom Recognition

Key Takeaways – महत्वपूर्ण बातें
Lung cancer dangerous है लेकिन early detection से treatable है
Persistent cough (2+ weeks) को ignore न करें – doctor दिखाएं
Blood in sputum = ALERT, तुरंत doctor को दिखाएं
Non-smokers को भी lung cancer हो सकता है – air pollution, genetics भी कारण हैं
Screening recommended है high-risk people के लिए (age 55-74, 30+ pack-years)
Early stage में 50-70% survival rate है vs late stage में 5-10%
Symptoms को track करिए – कितनी देर से हैं, क्या pattern है
Doctor को सभी symptoms बताएं – छोटा detail भी important हो सकता है
Regular health checkups करवाएं – especially अगर risk factors हों
Prevention बेहतर है cure से – smoking छोड़िए, pollution reduce करिए
