Unveiling the Hidden Causes: Most Lung Cancer Patients in India Never Smoked, Genetic Makeup a Big Driver
In India, a surprising majority of lung cancer patients have never smoked, highlighting the significant role of genetic factors in the disease's prevalence.
Most Lung Cancer Patients in India Never Smoked: Genetic Factors Driving Disease Prevalence
Lung cancer, often associated with smoking, reveals a surprising statistic in India: Current studies depict that around fifty percent of individuals diagnosed with lung cancer had never smoked in their lifetime. This shift alters the longstanding notion and indicates other prominent factors especially the genetic ones as primary factors influencing the emergence of the disease.
The Non-Smoking Majority: The new research suggests that more than half of the individuals diagnosed with lung cancer in India have never been smokers. This is contrary to the situation observed in other countries where smoking is well-known to cause lung cancer. The increase in lung cancer incidences among those who have never smoked is suggestive of risk factors that cannot be attributed to cigarette smoking, including: environmental factors and genetics.

The Genetic Connection: This has been identified as being one of the leading causes of lung cancer in individuals who do not smoke. We currently know genetic markers that can be associated with lung cancer in seconds. These alterations can produce lung-cancer cells regardless of tobacco habits, although smoking has long been considered the leading cause. These markers have been reported more frequently in India, and the hike in the number of non-smoking lung cancer cases suggest that these may be the possible reasons.
Environmental Factors: Apart from hereditary factors, other non-hereditary factors that lead to lung cancer include pollution, exposure to second-hand smoke, and hazardous substances in workplaces. Poor quality of air in India and its huge dependence on biomass fuels for cooking and heating further makes its population vulnerable to deteriorating lung health and may lead to lung cancer.

Conclusion: The fact that the majority of lung cancer patients in India are non-smokers shifts the attention from the most common risk factor, which is smoking. Lung cancer is one of the leading diseases that are characterized by the interaction of genetic susceptibility and environmental weaponry. Risk awareness, screening, and targeted biodiagnosis are crucial to manage this emerging disease and help the Indian population combat lung cancer properly.
