Air Pollution: Cancer's Unseen Cause

Air pollution is a significant threat to public health, with 99% of the world's population breathing unhealthy air. Exposure to air pollution can lead to lung cancer, as well as stroke, respiratory and cardiovascular diseases. Outdoor air pollution causes roughly 1 in 10 cases of lung cancer in the UK, and nearly half of lung cancer cases in people who have never smoked are estimated to be related to air pollution. Indoor air pollution, such as second-hand smoke from cigarettes, can also increase the risk of lung cancer. Air pollution contains a mixture of polluting particles, including tiny particles that may build up in the lungs and damage the DNA in cells, changing how cells divide and leading to cancer.

The risk of developing lung cancer from air pollution is far lower than the risk from smoking, which causes around nine times more cases. However, it is still a significant threat to public health, with 99% of the world's population breathing unhealthy air. Nearly half of lung cancer cases in people who have never smoked are estimated to be related to air pollution.

Indoor air pollution can also increase the risk of lung cancer. In the UK, a key source is second-hand smoke from cigarettes, cigars, and pipes. Burning wood and coal to heat homes or cook can also contribute to indoor air pollution. Most exposure to second-hand tobacco smoke happens in the home, and it can stay in the air for hours.

Indoor air pollution can increase the risk of lung cancer

Exposure to air pollution increases the risk of lung cancer. Indoor air pollution is a key contributor to this. In the UK, a major source of indoor air pollution is second-hand smoke from cigarettes, cigars and pipes. Burning wood and coal to heat homes or cook with also adds to indoor air pollution.

Most exposure to second-hand tobacco smoke (passive smoking) happens in the home, so it’s part of indoor air pollution. Smoke can spread from room to room and stay in the air for hours. Passive smoking can cause lung cancer and other health conditions like heart and lung diseases.

Air pollution contains a mixture of polluting particles. Tiny particles may build up in the lungs and damage the DNA in cells. This can change how cells divide, which can lead to cancer. Researchers are investigating how tiny particles may cause inflammation in the lungs that can lead to cancer.

It is important to keep in mind that while outdoor air pollution causes roughly 1 in 10 cases of lung cancer in the UK, smoking has a much bigger effect on the risk of developing lung cancer. It causes around nine times more lung cancer cases than air pollution.

Indoor air pollution can also increase the risk of lung cancer. In the UK, a key source of indoor air pollution is second-hand smoke from cigarettes, cigars, and pipes. Burning wood and coal to heat homes or cook with also adds to indoor air pollution. Most exposure to second-hand tobacco smoke (passive smoking) happens in the home, so it is considered indoor air pollution. Smoke can spread from room to room and stay in the air for hours.

The risks associated with air pollution are similar to those caused by smoking tobacco. Air pollution is a significant and far-reaching threat to public health, with 99% of the world's population breathing unhealthy air, according to the World Health Organization (WHO). Air pollution is now estimated to cause nearly seven million deaths per year.

Exposure to air pollution increases the risk of lung cancer. Outdoor air pollution causes roughly 1 in 10 cases of lung cancer in the UK, and nearly half of lung cancer cases in people who have never smoked are estimated to be related to air pollution.

Indoor air pollution can also increase the risk of lung cancer. In the UK, a key source of indoor air pollution is second-hand smoke from cigarettes, cigars and pipes. Burning wood and coal to heat homes or cook with also adds to indoor air pollution. Most exposure to second-hand tobacco smoke (passive smoking) happens in the home, so it is considered a form of indoor air pollution.

Air pollution contains a mixture of polluting particles, and there are a few ways in which it can cause lung cancer. For example, tiny particles may build up in the lungs and damage the DNA in cells. This can change how cells divide, which can lead to cancer. Researchers are also investigating how these particles may cause inflammation in the lungs, which can also lead to cancer.

It is estimated that air pollution causes nearly half of lung cancer cases in people who have never smoked. In the UK, outdoor air pollution causes roughly 1 in 10 cases of lung cancer. However, it's important to note that smoking has a much bigger impact on the risk of developing lung cancer, causing around nine times more cases than air pollution.

Indoor air pollution, such as second-hand smoke from cigarettes, cigars, and pipes, as well as burning wood and coal for heating or cooking, can also increase the risk of lung cancer. Most exposure to second-hand tobacco smoke (passive smoking) occurs indoors, and it can cause lung cancer and other health issues like heart and lung diseases.

While the focus is often on lung cancer, it is important to acknowledge that air pollution is linked to a range of other serious health issues, including stroke, respiratory, and cardiovascular diseases.
