scientists link increased air pollution to an uptick in cases of lung cancer

Sumary of Scientists link increased air pollution to an uptick in cases of lung cancer:

  • An international team of scientists, led by Nanyang Technological University, Singapore (NTU Singapore), has linked increased air pollution to an uptick in cases of lung adenocarcinoma (LADC) worldwide.
  • The same study also concluded an overall lower consumption of tobacco worldwide is statistically linked to less people contracting lung squamous cell carcinoma (LSCC).
  • Lung adenocarcinoma is a type of cancer for which research strongly suggests that genetic, environmental, and lifestyle factors play a part, while lung squamous cell carcinoma is often linked to a history of smoking.
  • The number of smokers worldwide decreased by 0.26 per cent a year, cumulatively falling by nearly six per cent from 1990 to 2012. Lung cancer remains the leading cause of cancer with an estimated 1.8 million deaths in 2020, according to CA: A Cancer Journal for Clinicians.
  • Professor Joseph Sung, NTU’s Senior Vice President (Health and Life Sciences) and Dean, Lee Kong Chian School of Medicine (LKCMedicine), who led the study, said: “In our study, we were able to determine that the global increase of lung adenocarcinoma is likely associated with air pollution.
  • Our study points to the importance of environmental factors in the causation of specific types of lung cancer.
  • ” Our study provided us with an indication as to the reason behind the rising trend of lung adenocarcinoma, despite the decreasing trend of smoking prevalence.
  • The statistics on pollution were obtained from National Aeronautics and Space Administration (NASA).
