Lung Cancer Awareness Month: Know the Risks and Protect Your Lungs

Despite being the leading cause of cancer cases and deaths worldwide (source: WHO), lung cancer rarely makes it to the headlines. What makes the scenario more concerning is the common misconception that it only affects people who smoke, which is far from the truth. Lung cancer can affect non-smokers too, with several other factors increasing a person's risk. Misconceptions like these highlight why awareness is so important. To help increase awareness about this life-threatening disorder, Lung Cancer Awareness Month is observed every year in the month of November. In line with the observance, today we'll understand why the month matters, the warning signs to look out for, and the steps you can take to lower your risk.

About Lung Cancer Awareness Month

Lung Cancer Awareness Month is observed every November to bring attention to one of the leading causes of cancer-related deaths worldwide. Awareness initiatives began in the United States in the 1990s, initially taking the form of a dedicated awareness day before expanding into week-long and month-long campaigns. Today, healthcare organisations, advocacy groups and communities in several countries participate in these efforts to educate the public about lung cancer.

The observance highlights the importance of recognising symptoms, understanding risk factors and seeking timely medical advice. It also challenges the stigma surrounding lung cancer, particularly the assumption that it only affects smokers. By advocating for better access to care, supporting patients and their families, and encouraging continued research, the month promotes a more informed and compassionate approach to the disease.

Understanding Lung Cancer and its Types

Lung cancer develops when abnormal cells in the lungs grow uncontrollably, forming tumours that can interfere with normal lung function and may spread to other parts of the body. It is one of the most commonly diagnosed cancers worldwide and can affect both smokers and non-smokers. 

Based on the type of cells involved and how the cancer grows, there are two main lung cancer types:

• Non-small cell lung cancer (NSCLC): This is the most common type of lung cancer, accounting for approximately 85% of cases. It includes adenocarcinoma, squamous cell carcinoma and large cell carcinoma. These cancers generally grow and spread more slowly than small cell lung cancer, although their behaviour varies depending on the subtype and stage.

• Small cell lung cancer (SCLC): This type accounts for approximately 10% to 15% of lung cancer cases. It tends to grow and spread more quickly than non-small cell lung cancer and is strongly associated with smoking. Early diagnosis and appropriate treatment are important in managing the disease.

What are the Early Signs of Lung Cancer?

Lung cancer may not cause noticeable symptoms in its early stages, which is one reason it can go undetected for some time. When symptoms do appear, they may resemble those of common respiratory illnesses. Some early symptoms of lung cancer to look out for include:

• Persistent Cough: A cough that does not go away or gradually worsens over time.

• Coughing up Blood: Blood in the sputum, even in small amounts, warrants prompt medical assessment.

• Shortness of Breath: Difficulty breathing during routine activities or breathlessness that is new or worsening.

• Chest Pain: Discomfort or pain in the chest that may worsen with deep breathing, coughing or laughing.

• Recurring Infections: Repeated episodes of bronchitis or pneumonia, particularly in the same area of the lung.

• Unexplained Weight Loss: Losing weight without changing your diet or activity levels.

• Persistent Fatigue: Feeling unusually tired or weak without an obvious explanation.

• Voice Changes: Hoarseness or a persistent change in the voice.

These symptoms do not necessarily indicate lung cancer, as they can occur with other conditions too.

What Increases Your Risk of Lung Cancer?

Smoking is the leading risk factor for lung cancer, but it is not the only one. Several environmental, occupational and personal factors can contribute to the development of the disease. The main risk factors include:

• Tobacco Smoking: Cigarette smoking is responsible for most lung cancer cases. The risk generally increases with the duration and amount of smoking.

• Second-Hand Smoke: Regular exposure to smoke from other people's cigarettes can increase the risk of developing lung cancer.

• Air Pollution: Long-term exposure to outdoor air pollution, including fine particulate matter, is associated with an increased risk.

• Radon Exposure: Radon is a naturally occurring radioactive gas that can accumulate indoors and damage lung tissue when inhaled over time.

• Occupational Exposure: Contact with substances such as asbestos, arsenic, diesel exhaust and certain industrial chemicals can increase lung cancer risk.

• Family History: Having a close relative with lung cancer may be associated with a higher risk, partly due to shared genetic and environmental factors.

• Previous Radiation Therapy: Radiation treatment to the chest for certain cancers may increase the risk of developing lung cancer later in life.

Having one or more risk factors does not mean a person will necessarily develop lung cancer. Similarly, people without recognised risk factors can still develop the disease.

Why Early Detection Can Save Lives

Early detection can make a meaningful difference in lung cancer care. When the disease is diagnosed before it has spread to other parts of the body, treatment may be more effective, and patients may have more treatment options available to them. 

There are two important ways lung cancer can be detected early:

• Early Diagnosis: This involves identifying the cause of symptoms as soon as possible. If you experience a persistent cough, unexplained breathlessness or other concerning changes, a healthcare professional may recommend imaging tests and, where necessary, a biopsy to determine the cause.

• Screening: Screening looks for lung cancer before symptoms appear. Low-dose computed tomography (LDCT) scans can help detect lung cancer in certain people at high risk, particularly those with a significant history of smoking. Screening eligibility depends on individual risk factors and applicable clinical guidelines.

Small Steps for Healthier Breaths: How Can You Lower Your Lung Cancer Risk

Not every case of lung cancer can be prevented, but reducing exposure to known risk factors can help lower your chances of developing the disease. Here are some practical steps to consider:

Quit Smoking

Avoiding tobacco is one of the most effective ways to reduce lung cancer risk. If you smoke, quitting can benefit your health at any age. Consider speaking to a healthcare professional about cessation programmes, counselling or treatments that can help you quit.

Avoid Second-Hand Smoke

Exposure to other people's tobacco smoke can also increase lung cancer risk. Keep your home and car smoke-free, and avoid environments where you are regularly exposed to tobacco smoke.

Reduce Pollution Exposure

Air pollution is a recognised lung cancer risk factor. Where possible, check local air quality reports, limit strenuous outdoor activity during periods of high pollution and improve indoor ventilation when outdoor conditions allow. These steps may reduce exposure, although they cannot eliminate the risk entirely.

Follow Safety Measures

Some workplaces expose people to carcinogens such as asbestos, silica and diesel exhaust. Follow workplace safety procedures, use appropriate protective equipment and raise concerns about unsafe exposure with your employer or occupational health team.

Check Your Risk

Discuss your personal and family medical history, smoking history and potential environmental exposures with a healthcare professional. They can help you understand your risk and determine whether lung cancer screening is appropriate for you. Avoid getting scans without medical guidance, as screening is intended for specific groups and has potential benefits and limitations.

How Can You Support People Living With Lung Cancer

A lung cancer diagnosis can affect every aspect of a person's life, from their physical health to their emotional well-being and relationships. Here are some ways you can offer support.

1. Listen Without Judgement

Give the person space to talk about their feelings, concerns and treatment experience. Avoid making assumptions about how they developed lung cancer or suggesting that their diagnosis is a result of their choices. A non-judgemental conversation can help them feel heard and respected.

2. Offer Practical Help

Treatment can make everyday tasks more difficult. You can offer to accompany someone to medical appointments, help with transport, prepare meals or assist with household responsibilities. Ask what they need instead of assuming what would be most helpful.

3. Encourage Emotional Support

Living with cancer can bring feelings of fear, uncertainty and isolation. Encourage patients to speak with a counsellor, join a cancer support group or seek help from a mental health professional if they feel overwhelmed. Respect their preferences and give them time to process their emotions.

4. Share Reliable Information

Help patients and caregivers find trustworthy information about treatment options, supportive care and available resources. Encourage them to discuss medical questions with their healthcare team rather than relying on unverified online advice.

5. Challenge The Stigma

Lung cancer can affect smokers and non-smokers alike. Avoid language that blames patients for their illness, and help challenge misconceptions when you encounter them. Promoting a more understanding attitude can make it easier for people to seek help and receive the support they deserve.

Take Action for Healthier Lungs and Brighter Futures

Lung Cancer Awareness Month is an opportunity to learn more about the disease, challenge common misconceptions and take meaningful steps towards better lung health. Most importantly, pay attention to changes in your health and encourage your loved ones to do the same. If you notice persistent or concerning symptoms, such as a cough that does not go away, unexplained breathlessness or coughing up blood, consult a pulmonologist promptly for an appropriate evaluation. Early medical assessment can help identify the cause of these symptoms and ensure that you receive the care you need.
