Lucknow is witnessing a concerning shift in lung cancer cases, with around 25% now being reported among non-smokers—many of whom are women and younger adults. Health experts highlighted this growing trend on the eve of World Lung Cancer Day, drawing a direct link to worsening air quality, indoor smoke exposure, and delayed detection in patients.
According to Prof. Ved Parkash, head of respiratory and critical care medicine at King George’s Medical University (KGMU), nearly 30% of lung cancer patients under his care have never smoked. “This trend is especially common in women and children exposed to outdoor air pollution, household smoke from biomass fuels in rural and semi-urban homes, and secondhand smoke in shared living spaces,” he explained. Prof. Parkash also referenced a recent study in Atmospheric Environment that revealed PM2.5 levels in Lucknow regularly exceed World Health Organization limits, with seasonal spikes intensifying the risk.
The study found that lung cancer in non-smokers is often associated with environmental pollutants, indoor toxins, genetic factors, and changing lifestyles. Notably, women may have increased biological vulnerability to these risks.
Dr. Abhishek Kumar Singh, director of medical oncology at Medanta Hospital, emphasized the threat posed by secondhand smoke and industrial fumes. “Secondhand tobacco smoke contains thousands of harmful chemicals. Paint fumes and industrial emissions elevate the risk further, leading not just to cancers, but also to asthma and bronchitis—especially among children and pregnant women. Preventing smoking in closed spaces and ensuring proper ventilation are key preventive steps,” he said.
Dr. Alok Gupta, senior director of medical oncology at Max Super Speciality Hospital, reported that long-term pollutant exposure can leave visible black deposits in the lungs of non-smokers. He listed other risks, such as unventilated cooking fumes, radon gas, and asbestos.
Dr. Dawar Masud Rizavi, associate director for pulmonology and sleep medicine at Apollo Hospital, added: “Radon exposure, industrial toxins, air pollution, and poorly ventilated indoor cooking can all increase lung cancer risk. While genetics may play a role in some families, many of these risk factors are preventable.”
