New Delhi, Aug 2: Lung cancer, long considered a smoker’s disease, is now affecting a growing number of non-smokers in India, raising alarm among health experts. Recent findings published in the Indian Journal of Cancer reveal that over 50% of lung cancer patients in the country are non-smokers, with diagnosis often delayed due to mild or overlooked symptoms.

Unlike other cancers that present visible signs, lung cancer often mimics common respiratory conditions, making early detection difficult. Shockingly, only 3.5% to 7.2% of patients are diagnosed in the early stages, drastically reducing chances of effective treatment and survival.

Doctors caution that symptoms like a persistent cough, coughing up blood, shortness of breath, unexplained chest pain, hoarseness, weight loss, and repeated chest infections should never be ignored. “Even one of these signs should prompt an immediate consultation,” said a senior oncologist, warning that lung cancer doesn’t announce itself loudly but builds silently over time.

Experts attribute the rising cases among non-smokers to worsening air pollution, exposure to second-hand smoke, and use of indoor fuels. The Indian Council of Medical Research (ICMR) has flagged air pollution—especially fine particulate matter (PM2.5)—as a major cause of lung cancer in non-smokers, with the disease now accounting for nearly 10% of all cancer deaths in India.

Despite the growing threat, awareness remains low. A recent study shows only 20% of patients are diagnosed while the cancer is still operable. Health officials urge the public to recognize warning signs and undergo timely screening to improve survival outcomes.

“Lung cancer doesn’t shout, but our body gives signals. Early attention can be a lifesaver,” said experts, calling for immediate nationwide awareness campaigns to address this silent epidemic.
