New findings from Mahajan Imaging & Labs, a leading diagnostic centre in Delhi, have revealed a troubling trend: nearly one in three young adults undergoing chest CT scans in the city and surrounding areas is showing signs of early lung damage. The internal review, which analyzed over 4,000 CT scans conducted in 2024, found that individuals as young as their 20s and 30s are increasingly presenting with structural lung abnormalities such as bronchiectasis, emphysema, fibrosis, and bronchial wall thickening.
These conditions, traditionally associated with older populations or individuals with significant smoking histories, are now appearing with notable frequency among urban youth. The data suggest a possible rise in early-stage chronic lung conditions, with contributing factors including infections, environmental pollution, smoking, vaping, and poor indoor air quality.
Dr. Harsh Mahajan, founder and chief radiologist at Mahajan Imaging & Labs, emphasized that these findings are not part of a peer-reviewed study but rather reflect diagnostic trends observed in routine clinical imaging. When cases linked to common infections and tumors were excluded, the proportion of young adults with lung abnormalities appeared even higher.
Health professionals point to Delhi’s persistently poor air quality—which often exceeds safe limits—as a major aggravating factor. The combination of outdoor and indoor pollution, along with increased tobacco consumption and delayed diagnosis of respiratory conditions, is putting young lungs under significant stress. “In cities like Delhi, where air quality remains a persistent concern, the lungs are already under considerable stress. In such a scenario, risk factors like tobacco exposure—whether direct or passive—could make matters worse,” said Dr. Mahajan.
The findings coincide with global anti-tobacco campaigns and highlight a broader concern: the lack of early screening and awareness among younger populations. Many young adults may not experience symptoms until lung damage is advanced, making early detection and intervention critical.
The trend is not unique to India. Countries like Brazil have also reported rising concerns over lung damage in youth, often linked to respiratory infections and environmental exposures. This underscores the need for greater attention to respiratory health, early detection measures, and public health initiatives focused on urban youth.
