Expert reveal why everyday habits increase lung cancer risk

According to the World Health Organisation, lung cancer remains the leading cause of cancer-related deaths globally for both men and women.

Dr Vijay Agarwal, a medical oncologist at Apollo Hospitals, Bengaluru, notes that several seemingly harmless everyday habits can quietly escalate the risk of developing this deadly disease over time.

Early detection and the elimination of known risk factors are the most critical tools for survival. Agarwal has outlined a comprehensive guide to the primary causes of lung cancer, many of which stem from easily avoidable lifestyle choices:

• Light Smoking: Tobacco smoke contains potent carcinogens like formaldehyde and benzene. Even occasional or "light" smoking leads to repeated cellular damage.
• Second-hand Smoke: Non-smokers remain at high risk in shared living spaces, cars, or workplaces where toxic substances linger in the air.
• Poor Kitchen Ventilation: Fumes from high-temperature frying and fuels like wood, coal, or kerosene release fine particles. Homemakers and professional cooks are particularly vulnerable to this persistent irritation.
• Environmental Pollution: Daily exposure to traffic emissions and construction dust (PM2.5) penetrates deep into the lungs, causing ongoing injury even in non-smokers.
• Occupational Hazards: Jobs involving welding, mining, or asbestos exposure significantly increase risk, especially when proper protective gear is absent.

The oncologist emphasises that there is no "safe" level of smoking, as the harm is cumulative. To lower the risk of lung cancer, Dr Agarwal recommends immediate practical changes:

• Ventilation: Improve airflow in kitchens by installing exhaust fans or chimneys and keeping windows open during cooking.
• Workplace Safety: For those in industrial or construction roles, consistent use of protective masks in dusty environments is essential.
• Fuel Choices: Whenever possible, transition to cleaner cooking fuels to reduce the inhalation of harmful particles.

By addressing these everyday habits and improving environmental conditions, individuals can significantly protect their long-term respiratory health.
