Lung Cancer a Major Threat Linked to Air Quality

Global Cancer Burden Growing, with Lung Cancer a Major Threat Linked to Air Quality

Global cancer cases to increase by 77% in 2050

New estimates from WHO and the International Agency for Research on Cancer (IARC) show there were an estimated 20 million new cancer cases and 9.7 million deaths in 2022. The estimated number of people who were alive within 5 years following a cancer diagnosis was 53.5 million. About 1 in 5 people develop cancer in their lifetime; approximately 1 in 9 men and 1 in 12 women die from the disease, according to the latest estimates.

Key Points:

  • In 2022, there were 20 million new cancer cases and 9.7 million deaths.
  • Lung cancer is the most common type of cancer in men and the second most common in women.
  • Exposure to air pollution, mainly due to particulate matter, is a major cause of lung cancer.
  • Approximately 22% of lung cancer deaths are attributed to air pollution.
  • WHO calls for urgent action to improve air quality and prevent lung cancer.

Emphasis on Lung Cancer and Air Quality:

  • Lung cancer is a leading cause of death worldwide, with over 2 million deaths annually.
  • Air pollution is a major risk factor for lung cancer, accounting for more than 1 in 5 lung cancer deaths.
  • Particulate matter, from sources such as traffic, industry, and wildfires, is the most harmful component of air pollution for the lungs.
  • WHO advocates for stricter air quality standards, cleaner energy sources, and better monitoring of air pollution.

Other Key Points:

  • Most cancer cases (60%) occur in low- and middle-income countries.
  • These countries often lack access to cancer prevention, diagnosis, and treatment.
  • WHO calls for increased investment in cancer control, particularly in low- and middle-income countries.

Conclusion:

The global cancer burden is growing, and lung cancer is a major threat. Air pollution is a significant risk factor for lung cancer, and urgent action is needed to improve air quality and prevent lung cancer.
