The majority of lung cancer cases in India are linked to non-smokers, a startling&nbsp;study has&nbsp;revealed. Factors such as genetic&nbsp;susceptibility, hormonal status and rise in poor air quality have&nbsp;been highlighted as the main cause of lung cancer in Indians.

The research was conducted at Mumbai-based Tata Memorial Centre and titled&nbsp;‘Uniqueness of lung cancer in Southeast Asia’. It has been published in medical journal&nbsp;The Lancet and the&nbsp;findings emphasised that lung cancer in Southeast Asia, particularly in India, stands apart from cases in other regions of the world.&nbsp;

"Lung cancer in Southeast Asia is similar but also very different in myriad aspects from that in the West, as well as other parts of Asia," the study stated.&nbsp;

Researchers noted that despite being non-smokers, lung cancer manifests among Indians, ten years earlier as compared to Western countries.&nbsp;

“Lung cancer presents approximately a decade earlier in India as compared to Western countries, with a mean age at diagnosis of 54–70 years,” read the report.

<h2>India and pollution&nbsp;</h2>

According to data, India accounted for&nbsp;72,510 lung cancer cases and 66,279 deaths in 2020. On the whole, lung cancer accounted for the third most commonly diagnosed cancer in Southeast Asia with 1.85 million new&nbsp;cases reported.&nbsp;&nbsp;&nbsp;

The study quoted a World Air Quality Report in 2022 and stated that South Asia is home to 37 of the 40 polluted cities across the world. India and its numerous tier-1, tier-and 2 cities, including the capital New Delhi, remain polluted nearly throughout the year - further increasing the risk of cancer among non-smokers.&nbsp;

Exposure to particulate matter PM2.5,&nbsp;asbestos, chromium, cadmium, arsenic and coal as well as passive smoking are the contributing factors.

The study highlighted that only 31.7 per cent of patients in India with Stages I to IIIB lung cancer, underwent curative intent therapy while only 13.4 per cent underwent curative resection.&nbsp;&nbsp;

The research concluded that a "fair amount of work" had&nbsp;been done, "but there is a lot more that can and should be done to ensure that all patients with lung cancer receive the same level of high-quality care, regardless of their geographical location or ethnicity".
