Lung cancer rates surge among non-smokers — could any one of us be the next victim?
1. On the verge of crisis
You might assume, ‘I don't smoke, so I won't get lung cancer.’But the facts tell a different story. Among global lung cancer patients, the proportion of lifelong non-smokers is steadily rising. The United States can be an example: approximately 10%–20% of lung cancer cases occur in individuals who have never smoked in their lifetime each year. Furthermore, the recently published State of Global Air Report (2025) reveals that around 7.9 million people worldwide died prematurely due to air pollution in 2023. Air pollution has now surpassed traditional risks such as tobacco use and poor diet to become the second leading cause of death globally, trailing only hypertension.
Even more alarming is that over 90% of these deaths are linked to fine particulate matter (PM2.5) — these microscopic pollutants can penetrate deep into the alveoli, pass through the lung walls into the bloodstream, and potentially cause damage to the cardiovascular and respiratory systems, the immune system, and even genetic material.
In other words, air pollution is no longer confined to specific cities or nations; it has become a global “invisible epidemic”. Wherever you are, as long as you breathe daily, you may be affected by this crisis.
2. Global predicament
Looking back at history, the Great Smog of London in 1952 resulted in at least 4,000 direct deaths and respiratory damage affecting tens of thousands. Entering the 21st century, from forest fire smoke in North America to smog alerts in cities like Los Angeles, Tokyo, Beijing, and Delhi, the threat of air pollution to lung health continues to escalate. Particularly in Southeast Asia today, motorcycle exhaust fumes, traffic congestion, industrial emissions, cooking fumes, and seasonal haze collectively form the primary sources of air pollution. Persistently elevated levels of PM2.5 and ozone pollutants have made daily coughing, respiratory discomfort, and heightened sensitivity commonplace for urban residents.
3. Experience in Europe and America
In response to this trend, consumers in Europe and America have pioneered a shift towards ‘natural nutrition + lung health’ solutions. Quercetin, prized for its natural origins, high safety profile, and potent antioxidant properties, is regarded as a key ingredient for alleviating respiratory inflammation and countering pollution-induced damage. For instance, Quercetin with Bromelain by Now Foods, a long-established American dietary supplement company, consistently ranks among Amazon's bestsellers in respiratory health and immune support. Not only does it support respiratory health and alleviate inflammatory stress caused by air pollution, but its high absorption efficiency and synergistic anti-inflammatory effects have also earned widespread consumer recognition. This reflects both consumer trust in and demand for ‘natural, daily, long-term lung care’ solutions.
