Lung Cancer Awareness Month: Symptoms, Risk Factors, Screening, Diagnosis and Treatment

Every November, Lung Cancer Awareness Month is observed to increase understanding of lung cancer, encourage people at higher risk to discuss screening with their doctor, and promote earlier evaluation of persistent respiratory symptoms.

Lung cancer remains one of the most serious forms of cancer worldwide. It develops when abnormal lung cells begin to grow uncontrollably. These cells may form a tumour and, if not detected and treated, can spread to lymph nodes or other organs such as the brain, liver, bones or adrenal glands.

The two major types are:

• Non-small cell lung cancer (NSCLC)
• Small cell lung cancer (SCLC)

Treatment differs depending on the cancer type, stage, molecular characteristics, and the patient’s overall health.

One of the biggest challenges with lung cancer is that many people do not develop obvious symptoms until the disease is more advanced. That makes awareness of warning signs, risk factors and screening especially important.

At Metro Hospital, Faridabad, patients with a persistent cough, blood in sputum, suspicious chest imaging or other possible lung-cancer symptoms can seek evaluation through the Pulmonology Respiratory & Sleep Medicine Department, which manages lung cancer and provides diagnostic procedures including bronchoscopy. Patients diagnosed with cancer can also access multidisciplinary treatment through Metro Cancer Institute, including medical oncology, surgical oncology and radiation oncology.

This detailed guide explains the importance of Lung Cancer Awareness Month, early symptoms, major risk factors, screening, diagnosis, treatment options and practical steps that may reduce risk.

When Is Lung Cancer Awareness Month?

Lung Cancer Awareness Month is observed throughout November.

The International Association for the Study of Lung Cancer identifies November as Lung Cancer Awareness Month, while the American Lung Association uses the month to raise awareness, encourage screening discussions and support people living with lung cancer.

The month focuses attention on:

• Early warning signs
• Lung cancer screening
• Smoking cessation
• Risk factors beyond smoking
• Research
• Modern treatment options
• Patient and family support

Why Lung Cancer Awareness Matters

Lung cancer can be difficult to identify in its early stages because symptoms may be mild, vague or mistaken for other respiratory problems.

For example, a persistent cough may be blamed on:

• Pollution
• Smoking
• Asthma
• Allergy
• Infection
• Acid reflux

Similarly, fatigue and weight loss may be attributed to stress or poor nutrition.

The CDC notes that many people with lung cancer do not develop symptoms until the disease has become more advanced.

This makes persistent or unexplained symptoms especially important to investigate.

What Is Lung Cancer?

Lung cancer occurs when abnormal lung cells grow uncontrollably.

These abnormal cells can:

• Form a tumour
• Damage normal lung tissue
• Spread to nearby lymph nodes
• Spread to distant organs

The two major types differ in their behaviour and treatment.

Non-Small Cell Lung Cancer

NSCLC accounts for most lung cancers.

Common subtypes include:

• Adenocarcinoma
• Squamous cell carcinoma
• Large-cell carcinoma

Treatment may involve:

• Surgery
• Radiation therapy
• Chemotherapy
• Targeted therapy
• Immunotherapy

Depending on stage and molecular findings.

Small Cell Lung Cancer

Small cell lung cancer tends to grow and spread more quickly.

Treatment often involves:

• Chemotherapy
• Radiation therapy

Surgery is used less commonly because the disease is frequently widespread by the time of diagnosis.

Common Symptoms of Lung Cancer

Lung cancer symptoms vary between individuals.

The CDC lists the following among common warning signs: persistent or worsening cough, chest pain, breathlessness, wheezing, coughing up blood, persistent fatigue and unexplained weight loss.

1. Persistent or Worsening Cough

A cough lasting several weeks deserves medical attention, especially if it:

• Keeps getting worse
• Changes in character
• Occurs with chest pain
• Is accompanied by blood
• Occurs with unexplained weight loss

A persistent cough does not automatically mean lung cancer, but it should not be ignored.

2. Coughing Up Blood

Blood in sputum can appear as:

• Small streaks
• Pink mucus
• Larger amounts of blood

Possible causes include:

• Infection
• Tuberculosis
• Bronchiectasis
• Lung cancer

Any unexplained coughing of blood should be medically evaluated.

Metro Hospital’s Pulmonology Department uses bronchoscopy to evaluate problems such as blood in phlegm, suspicious radiological shadows, and lung cancer.

3. Chest Pain

Lung cancer may sometimes cause persistent chest pain.

The pain may:

• Worsen with coughing
• Increase with deep breathing
• Remain localised

Chest pain has many other possible causes, including heart disease, infection and musculoskeletal problems, so proper evaluation is necessary.

4. Shortness of Breath

Breathlessness may occur if:

• A tumour narrows an airway
• Fluid accumulates around the lungs
• Normal lung function is reduced

Persistent unexplained breathlessness should be assessed.

5. Wheezing

Wheezing can occur when an airway becomes narrowed.

Asthma and COPD are much more common causes, but new or persistent wheezing may require investigation.

6. Unexplained Weight Loss

Weight loss without dieting may occur with several cancers, including lung cancer.

Seek medical evaluation if weight loss is:

• Persistent
• Unintentional
• Associated with poor appetite
• Accompanied by fatigue or respiratory symptoms

7. Persistent Fatigue

Lung cancer can cause significant tiredness.

But fatigue is also common with:

• Anaemia
• Thyroid disease
• Infection
• Sleep disorders
• Nutritional deficiencies

Interpret persistent fatigue alongside other symptoms.

8. Recurrent Pneumonia or Chest Infections

Repeated infections affecting the same part of the lung may occasionally occur because a tumour blocks an airway.

CDC notes that recurrent pneumonia can sometimes occur in people with lung cancer.

9. Hoarseness

Persistent hoarseness may occasionally develop if a tumour affects nerves controlling the vocal cords.

If hoarseness lasts for weeks without an obvious infection, it should be evaluated.

10. Swollen Lymph Nodes

Some patients may develop enlarged lymph nodes around:

• Neck
• Collarbone
• Chest

CDC notes that swollen or enlarged lymph nodes in the chest may occur in lung cancer.

What Is the Biggest Risk Factor for Lung Cancer?

Cigarette smoking is the most important risk factor.

CDC states that smoking is the number-one risk factor for lung cancer.

The longer someone smokes and the greater the number of cigarettes consumed, the higher the risk generally becomes.

However, lung cancer is not exclusively a smoker’s disease.

Can Non-Smokers Get Lung Cancer?

Yes.

People who have never smoked can develop lung cancer.

Possible risk factors include:

• Secondhand smoke
• Radon
• Occupational exposure
• Air pollution
• Family history
• Genetic factors

The CDC specifically notes that lung cancer can occur in people who never smoked and that risk factors beyond smoking exist.

Secondhand Smoke and Lung Cancer

Secondhand smoke exposes non-smokers to many of the same carcinogenic substances found in tobacco smoke.

CDC identifies secondhand smoke as a cause of lung cancer in adults who have never smoked.

Keeping homes and vehicles smoke-free is therefore important.

Radon and Lung Cancer

Radon is a naturally occurring radioactive gas.

Long-term exposure can increase lung-cancer risk.

CDC identifies radon as an important lung-cancer risk factor after smoking in the United States.

Occupational Exposure

Certain workplace exposures can increase risk.

Examples may include:

• Asbestos
• Silica
• Diesel exhaust
• Certain industrial chemicals

Workers in high-risk environments should follow occupational safety guidelines.

Air Pollution and Lung Cancer

Long-term exposure to air pollution can increase lung-cancer risk.

This is particularly relevant for people living in highly polluted urban environments.

Reducing exposure where possible and avoiding smoking remain important preventive steps.

How Is Lung Cancer Diagnosed?

Diagnosis usually begins after:

• Symptoms
• Abnormal chest X-ray
• CT finding
• Screening result

Further evaluation may include:

Chest CT Scan

CT can identify:

• Lung nodules
• Tumours
• Enlarged lymph nodes
• Other chest abnormalities

PET-CT

PET-CT may help determine whether cancer has spread and can support staging and treatment planning.

Metro Cancer Institute lists in-house PET-CT among its diagnostic capabilities for cancer staging and treatment assessment.

Bronchoscopy

Bronchoscopy involves passing a thin camera into the airways.

It can help:

• Visualise abnormalities
• Take biopsies
• Investigate bleeding
• Evaluate suspicious lesions

Metro Hospital’s Pulmonology Department routinely performs video-assisted bronchoscopy and lists lung cancer among the conditions for which bronchoscopy is used.

EBUS and Tissue Sampling

Endobronchial ultrasound, or EBUS, may help sample lymph nodes and abnormalities near the airways.

Specialist pulmonologists can use this technique to support lung-cancer diagnosis and staging.

Biopsy

A biopsy is usually required to confirm lung cancer.

Samples may be obtained using:

• Bronchoscopy
• EBUS
• CT-guided biopsy
• Surgery

A pathologist then examines the tissue.

What Is Lung Cancer Screening?

Screening means testing people who have no symptoms but may have a high risk of developing lung cancer.

The recommended screening method for high-risk adults is low-dose CT (LDCT).

CDC states that LDCT is the recommended lung-cancer screening test for adults at high risk because of age and smoking history.

Screening is different from investigating symptoms.

If someone has a persistent cough, blood in sputum, or unexplained weight loss, they need a diagnostic evaluation rather than a screening test.

Who Should Consider Lung Cancer Screening?

Screening guidelines vary by country and organisation.

Current U.S. recommendations cited by the CDC advise annual LDCT for people who:

• Are 50–80 years old
• Have at least a 20 pack-year smoking history
• Currently smoke or quit within the past 15 years

These criteria should not automatically be applied to everyone in India.

People should discuss their individual risk and appropriate screening strategy with a qualified pulmonologist or oncologist.

What Is a Pack-Year?

A pack-year measures smoking exposure.

Examples:

• 1 pack per day for 20 years = 20 pack-years
• 2 packs per day for 10 years = 20 pack-years

This helps doctors estimate smoking-related risk.

What Happens After Lung Cancer Is Diagnosed?

The next step is staging.

Staging determines:

• Tumour size
• Lymph-node involvement
• Whether cancer has spread

Treatment depends heavily on the stage.

Lung Cancer Treatment Options

Modern lung-cancer treatment is increasingly personalised.

Depending on cancer type and stage, treatment may include:

• Surgery
• Chemotherapy
• Radiation therapy
• Targeted therapy
• Immunotherapy

Metro Cancer Institute lists lung cancer among the solid tumours treated through its multidisciplinary Medical, Surgical and Radiation Oncology programme.

Lung Cancer Surgery

Surgery is generally considered for selected patients with localised non-small cell lung cancer.

Procedures may include:

Lobectomy

Removal of one lobe of the lung.

Pneumonectomy

Removal of an entire lung in selected cases.

Metro Hospital’s Surgical Oncology Department lists lobectomy and pneumonectomy among lung-cancer surgical procedures.

Chemotherapy for Lung Cancer

Chemotherapy uses medicines that destroy or control rapidly dividing cancer cells.

It may be used:

• Before surgery
• After surgery
• With radiation
• For advanced disease

Treatment depends on cancer type and stage.

Targeted Therapy

Some non-small cell lung cancers have genetic alterations that specific medicines can target.

Testing may look for changes involving genes such as:

• EGFR
• ALK
• ROS1
• KRAS
• Other actionable alterations

This is why molecular testing has become an important component of modern lung-cancer treatment.

Immunotherapy

Immunotherapy helps the immune system recognise or attack cancer cells.

It may be used:

• Alone
• With chemotherapy
• In selected early-stage settings
• In advanced lung cancer

Suitability depends on the cancer subtype and biomarkers.

Radiation Therapy

Radiation treatment can be used in:

• Early-stage lung cancer when surgery is not suitable
• Locally advanced disease
• Symptom control
• Metastatic disease

Metro Cancer Institute’s Radiation Oncology Department provides advanced techniques including:

• IMRT
• IGRT
• SBRT
• SRS
• 3D-CRT

using TrueBeam with HyperArc technology.

SBRT for Lung Cancer

Stereotactic Body Radiation Therapy delivers highly focused radiation to selected tumours.

It may be used in certain patients with early-stage lung cancer who are not suitable surgical candidates.

Treatment suitability depends on:

• Tumour size
• Location
• Stage
• Lung function
• Overall health

Multidisciplinary Lung Cancer Care

Lung cancer care often requires coordination between:

• Pulmonologist
• Medical oncologist
• Thoracic or surgical oncologist
• Radiation oncologist
• Radiologist
• Pathologist
• Nuclear medicine specialist

Metro Cancer Institute provides multidisciplinary oncology services integrating Medical, Surgical and Radiation Oncology along with advanced diagnostics.

Lung Cancer and Bronchoscopy at Metro Hospital

Respiratory evaluation often begins with a pulmonologist.

Metro Hospital’s Pulmonology, Respiratory & Sleep Medicine Department manages lung cancer and provides:

• Video-assisted bronchoscopy
• Pulmonary function tests
• Critical-care respiratory support
• Thoracic surgical coordination

The department specifically lists unexplained respiratory symptoms, blood in sputum and lung cancer among the indications for bronchoscopy.

Lung Cancer Specialist Care at Metro Hospital

Dr. Hemant Goel is Director & HOD – Respiratory & Sleep Medicine (Unit-I) at Metro Hospital, Faridabad.

His listed areas of expertise include:

• Lung cancer
• Bronchoscopy
• EBUS
• Thoracoscopy
• CT-guided respiratory procedures
• COPD
• Interstitial lung disease

Can Lung Cancer Be Prevented?

Not every lung cancer can be prevented, but you can often reduce your risk.

1. Do Not Smoke

Avoiding tobacco is the most important preventive measure.

CDC recommends never starting to smoke or quitting if you currently smoke.

2. Quit Smoking

It is never too late to quit.

Stopping smoking reduces future lung-cancer risk and also improves:

• Heart health
• Lung function
• COPD risk
• Stroke risk

3. Avoid Secondhand Smoke

Keep your:

• Home
• Workplace
• Car

as smoke-free as possible.

4. Reduce Occupational Exposure

Use appropriate protective equipment and follow workplace safety guidance.

5. Discuss Screening if You Are High Risk

People with significant smoking exposure should discuss whether LDCT screening is appropriate.

Common Myths About Lung Cancer

Myth 1: Only Smokers Get Lung Cancer

False.

Smoking is the most important risk factor, but people who never smoked can also develop lung cancer.

Myth 2: If I Feel Well, I Cannot Have Lung Cancer

False.

Many lung cancers do not cause symptoms in the early stages.

Myth 3: A Chest X-Ray Can Rule Out Every Lung Cancer

No.

CT provides more detailed lung imaging and may identify abnormalities not visible on a standard X-ray.

Myth 4: Lung Cancer Cannot Be Treated

False.

Modern treatments include surgery, radiation therapy, chemotherapy, targeted treatment and immunotherapy.

Treatment options continue to improve.

When Should You See a Pulmonologist?

Consult a respiratory specialist if you experience:

• Persistent cough
• Coughing blood
• Recurrent pneumonia
• New wheezing
• Persistent chest pain
• Unexplained breathlessness
• Unexplained weight loss

Earlier evaluation can help determine whether symptoms are caused by cancer or a more common respiratory condition.

When Should You Seek Urgent Care?

Seek urgent medical attention for:

• Significant coughing of blood
• Severe breathlessness
• Sudden severe chest pain
• Fainting
• Severe respiratory distress

Do not delay emergency care while waiting for a routine appointment.
