Big disclosure about diseases caused by air pollution
air pollution causes lung cancer
More than 25% of lung cancer due to air pollution in India
New Delhi: Pollution is a global problem. Rapidly increasing air pollution has emerged as the biggest concern. Now doctors have disclosed about the harmful diseases caused by air pollution. Due to air pollution, where side effects like asthma and chronic cough come to the fore, now doctors have made a big disclosure about the disease caused by air pollution.
The question always comes up as to what causes lung cancer in non-smokers? Lung cancer in non-smokers has always given scientists no real insight into the causes of the disease, as most lung cancers in non-smokers are thought to result from genetic mutations. But now air pollution is also being considered as a major reason for this.
air pollution is a major cause of cancer
According to Hindustan Times, in an interview with him, Dr Mrinal Parab, consultant surgical oncologist at Masina Hospital in Mumbai, explained that “indoor and outdoor air pollution can lead to lung cancer as well as heart disease, COPD. Pollutants in the toxic air can cause cancer. The most common cause of lung cancer is clearly smoking. But air pollution is the second most common cause of cancer after adjusting for smoking-related deaths.
Mrinal Pranab pointed out that “The pollutants in toxic air that can cause cancer are arsenic, asbestos, benzene, beryllium, cadmium, coal tar, silica, ethylene oxide, wood dust, trichlorethylene, thorium, Nike compounds, tar indoor Fumes of combustion, coal particles, vinyl chloride, chemicals. These are commonly found in industrial areas as well as metro cities (due to the use of coal, crude oil, petrol, diesel). Burning of plastics and other waste materials increases the amount of aromatic carbon compounds in the air. This is one of the main causes of cancer. Smog is air with dense heavy air pollutant particles and is dangerous as it can cause chronic bronchitis, COPD, asthma, allergic rhinitis and lung cancer the most common being adenocarcinoma.

Mrinal Pranab reveals that all these pollutants cause persistent inflammation and irritation in the upper and lower airways. He further added that “DNA alterations also hinder repair of DNA damage, resulting in defective DNA propagation in the cell cycle. This leads to irreversible genetic changes. These changes lead to tumor formation and cancer. Chronic cough, wheezing, COPD, asthma, coughing up blood, difficulty in breathing, weakness, change in voice and finally cancer formation are the initial symptoms which lead to cancer formation. Lung cancer related to air pollution is mostly adenocarcinoma.
Dr Sewanti Limaye, Director of Oncology and Precision Medicine at Sir HN Reliance Foundation Hospital, told Hindustan Times that in a recent research study with around 45,000 people in the UK, it was found that large dust particles more than 2.5 um in size Mutations in the EGFR gene can lead to a specific type of lung cancer. He said that “This type of lung cancer is seen in 25% of lung cancers in India and the highest proportion of lung cancer is seen in non-smokers.
