In India, lung most cancers accounts for an annual incidence of 72,510 instances (5.8%) and 66,279 deaths (7.8%).
Highlighting the “uniqueness” of Indian sufferers, one of many authors, Dr Kumar Prabash from Tata Medical Centre’s medical oncology division, on Tuesday informed TOI that “over 50% of our lung most cancers sufferers are non-smokers“.
The research stated the essential danger elements for lung most cancers in non-smokers included air air pollution (particularly particulate matter PM2.5), occupational publicity to asbestos, chromium, cadmium, arsenic and coal in addition to second-hand smoke at dwelling.
