Pollution And Cancer: Is There A Link?

Air pollution is a major public health concern, and has been linked to lung cancer. Particulate matter—small, airborne particles—can build up in the lungs and cause changes to airway cells, which can lead to cancer. A 2020 American Cancer Society review in CA: A Cancer Journal for Clinicians found that air pollution is the second leading cause of lung cancer after smoking, and may also be a possible cause of other cancers, including bladder, breast, kidney, colon and rectal cancer. However, studies regarding these cancers are less conclusive, and research is ongoing.

Air pollution and lung cancer

Air pollution is a major public health concern, and has been linked to lung cancer. Air pollution contains a mixture of polluting particles, including particulate matter, which are small, airborne particles. These particles can build up in the lungs and damage the DNA in cells, changing how they divide and potentially leading to cancer. Hundreds of thousands of lung cancer deaths worldwide are attributed to air pollution, and it is the second leading cause of lung cancer after smoking.

Research has shown that changes in airway cells that trigger lung cancer are visible in about half of people with lung cancer who have never smoked. This suggests that air pollution can cause lung cancer even in those who are not exposed to other risk factors such as smoking.

The Lancet Commission on pollution and health established that all forms of pollution cause 43% of lung cancer deaths, with air pollution alone causing up to 29% of all lung cancer deaths. This highlights the significant impact of air pollution on lung cancer risk.

While the link between air pollution and lung cancer is well-established, the specific mechanisms by which air pollution causes lung cancer are still being investigated. Researchers are studying how tiny particles in air pollution may cause inflammation in the lungs that can lead to cancer. Additionally, air pollution may also increase the risk of other cancers, including bladder, breast, kidney, colon, and rectal cancer. However, studies regarding these cancers are less conclusive, and more research is needed.

Particulate matter and lung cancer

Air pollution from particulate matter, or small, airborne particles, has been linked to lung cancer. According to a 2020 American Cancer Society review, it is the second leading cause of lung cancer after smoking, and is responsible for hundreds of thousands of lung cancer deaths worldwide.

Particulate matter can cause changes in airway cells that trigger lung cancer. These changes are visible in about half of people with lung cancer who have never smoked. Research has shown that the same particles that contribute to climate change are impacting human health via a cancer-causing mechanism in lung cells.

The particles may build up in the lungs and damage the DNA in cells, changing how they divide, which can lead to cancer. Researchers are also investigating how these particles may cause inflammation in the lungs, which could be another cause of lung cancer.

The Lancet Commission on pollution and health established that all forms of pollution cause 43% of lung cancer deaths, with air pollution alone causing up to 29% of these deaths.

Air pollution and other cancers

Air pollution has been closely associated with lung cancer. Hundreds of thousands of lung cancer deaths worldwide are attributed to air pollution, which is the second leading cause of the disease after smoking.

Air pollution contains a mixture of polluting particles, including particulate matter—small, airborne particles. These particles can build up in the lungs and damage the DNA in cells, changing how they divide and leading to cancer. Research has also suggested that air pollution may cause inflammation in the lungs, which can also lead to cancer. Studies have shown that these changes are visible in about half of people with lung cancer who have never smoked.

While air pollution has been conclusively linked to lung cancer, its connection to other cancers is less clear. A 2020 review by the American Cancer Society noted some evidence to suggest that air pollution may be a possible cause of bladder cancer, breast cancer, kidney cancer, colon cancer and rectal cancer. However, studies regarding these cancers are less conclusive, and research is ongoing.

Air pollution is a major public health concern, and authorities have worked for decades to study and reduce its negative effects on health, including its relationship to cancer. It is largely a human-made problem, resulting from sources such as manufacturing, energy production, farming, flying, driving, shipping, wildfires, and home fireplaces.

Pollution in water

Pollution is a major public health concern, and there is a close association between pollution and cancer risk.

Air pollution is the most well-studied type of pollution in relation to cancer, and it has been linked to an increased risk of lung cancer. Hundreds of thousands of lung cancer deaths worldwide are attributed to air pollution, and it is the second leading cause of lung cancer after smoking. Air pollution contains a mixture of polluting particles, including particulate matter—small, airborne particles. These particles can build up in the lungs and damage DNA in cells, changing how cells divide and leading to cancer. Research is also investigating how these particles may cause inflammation in the lungs, which could also lead to cancer.

While air pollution is the most studied type of pollution in relation to cancer, other kinds of pollution, including water pollution, may also have an effect on cancer risk. Water pollution occurs when harmful substances, or pollutants, make their way into water sources. These pollutants can come from a variety of human-made sources, including manufacturing, energy production, farming, flying, driving, shipping, and more.

While the specific effects of water pollution on cancer risk are not as well-studied as air pollution, it is important to recognize that pollution in any form can have negative consequences on human health. More research is needed to fully understand the relationship between water pollution and cancer risk.

Wildfires and air pollution

Air pollution is a major public health concern. It is closely associated with lung cancer, with hundreds of thousands of lung cancer deaths worldwide attributed to air pollution. According to a 2020 American Cancer Society review, air pollution is the second leading cause of lung cancer after smoking.

Wildfires are a source of air pollution. They release harmful substances, known as pollutants, into the air. These pollutants include a mixture of particles that can build up in the lungs and damage the DNA in cells. This can change how cells divide, which can lead to cancer.

Research has shown that exposure to particle pollution can cause changes in airway cells that trigger lung cancer. These changes have been visible in about half of people with lung cancer who have never smoked. The same particles that contribute to climate change are impacting human health through a cancer-causing mechanism in lung cells.

The Lancet Commission on pollution and health established that air pollution causes up to 29% of all lung cancer deaths. This is a significant proportion, highlighting the need to reduce air pollution and protect public health. Strategies to reduce outdoor air pollution are crucial to decrease the risk of lung cancer and other health issues associated with air pollution.
