Air Pollution Linked to Rise in Lung Cancer Cases Among Non-Smokers

Lung cancer cases among non-smokers have reached an alarming number, with the UK’s NHS reporting around 43,000 diagnoses every year. Historically, lung cancer was closely linked to smoking, but researchers have now identified air pollution as a major contributor to worldwide cases of lung cancer.

According to a study published in The Lancet Respiratory Medicine journal, air pollution is a significant cause of adenocarcinoma, a non-small cell lung cancer type that develops in the glandular tissues lining the lungs. Cancer Research UK estimates that 80-85% of lung cancers are NSCLC, and about 15% of all adenocarcinoma cases in 2022 were likely caused by air pollution.

The study found that these cases were predominantly among women and East Asian populations, such as those in China. The researchers emphasize the urgent need to investigate the link between lung cancer and air pollution, particularly as the proportion of lung cancers diagnosed among non-smokers increases globally.

A World Health Organisation (WHO) report from 2019 states that 99% of the world’s population lives in areas where air quality guidelines are not met. This suggests a strong correlation between exposure to poor air quality and an increased risk of developing adenocarcinoma.

Symptoms of lung cancer include persistent cough, breathlessness, chest infections, and unexplained weight loss. If you’re experiencing any of these symptoms or have concerns about your health, contact Macmillan’s Cancer Support Line on 0808 808 00 00 for confidential support.
