Lung Cancer Rising Among Non-Smokers Across Asia, Experts Warn

Lung cancer remains the leading cause of cancer death worldwide, with a notable rise in cases among non-smokers, particularly women and individuals in Asia, where environmental factors such as radon gas, air pollution, and radiation contribute to its development. Non-smokers often receive diagnoses at advanced stages due to subtle early symptoms and a lack of suspicion for lung cancer in this group. Research highlights that genetic mutations, or driver mutations, play a significant role in lung cancers among non-smokers, differentiating these cases from those caused by smoking. Early detection methods have evolved from chest X-rays to low-radiation CT scans, improving the chances of timely diagnosis and treatment. Additionally, lung cancer complications, including metastasis to organs like the brain and bones, cause symptoms such as pain and breathing difficulties, which require careful symptom management. In China, disparities in lung cancer treatment and costs are exacerbated by a tiered social health insurance system that affects access to care, underscoring the need for policy reforms to improve equity.
