Lung Cancer Awareness Month 2025

• November is globally observed as Lung Cancer Awareness Month , focusing on education, prevention, and early detection of the world’s leading cause of cancer deaths. While tobacco use remains the primary cause, recent studies have confirmed air pollution —particularly fine particulate matter (PM2.5)—as a growing environmental driver of lung cancer, even among non-smokers.

Rising Threat of Air Pollution

• The International Agency for Research on Cancer (IARC) has classified outdoor air pollution and PM2.5 as Group 1 carcinogens , placing them in the same risk category as tobacco smoke and asbestos. These microscopic particles can penetrate deep into the lungs, cause chronic inflammation, damage DNA, and lead to lung adenocarcinoma . Studies indicate that up to 18% of global lung cancer deaths are linked to air pollution exposure, with urban areas and developing nations facing the highest risks.

Prevention and Individual Measures

• Although policy-level action is essential, individuals can significantly reduce their exposure. Quitting smoking remains the single most effective preventive step. People can also use HEPA filters indoors , switch to clean cooking fuels , and ensure proper ventilation in homes. During periods of high air pollution, wearing N95 masks , avoiding outdoor physical activity , and staying indoors can help lower exposure.

Policy and Public Health Interventions

• Governments play a vital role in addressing pollution-driven cancer risks. Policies promoting cleaner transport , industrial emission controls , renewable energy , and urban green zones are proven to lower pollution levels and related cancer rates. Public health initiatives, including awareness campaigns, screening drives, and early detection programs , can dramatically improve survival outcomes. For high-risk individuals aged 50–80 years with a history of heavy smoking, annual low-dose CT scans are recommended for early diagnosis.

Awareness and Global Commitment

• Lung Cancer Awareness Month 2025 reinforces that prevention extends beyond tobacco control to include environmental health . No major global city currently meets WHO air quality standards , underlining the urgency for collective action. Through public education , reduced pollutant exposure , and timely screening , the burden of lung cancer can be effectively reduced worldwide.

Exam Pointers:

• IARC classifies PM2.5 and air pollution as Group 1 carcinogens .

• 18% of global lung cancer deaths linked to air pollution.

• Low-dose CT scans recommended for high-risk groups (50–80 years).

• Clean energy and emission control reduce cancer risks.

• Awareness Month: November (Lung Cancer Awareness Month).
