Air pollution has emerged as one of the biggest health issues, most importantly in relation to its growing occurrence of lung cancer. Though smoking is still the most common cause of lung cancer, epidemiological evidence now indicates that air pollution, particularly PM2.5, also significantly contributes to the incidence, even among non-smokers.
Dr. Sudhir Palsaniya, Consultant Medical Oncologist, Shalby Jaipur, explains that prolonged exposure to PM2.5 can trigger inflammatory reactions in pulmonary cells, which might subsequently lead to the development of cancer. This scenario is pretty alarming for people staying in urban areas with higher vehicle and industrial pollution levels.
The Science Behind the Connection
Exposure to air pollution damages lung tissue while promoting tumor growth. PM2.5 refers to fine particulate matter that has a size of less than 2.5 micrometers. The penetration level of this matter within the respiratory system is quite very high. These particulates work like promoters, which brings cell mutations to become malignant cancerous cells. Doctors Shalby Hospital, Jaipur, says “Even nonsmokers have fallen prey to it. That is to say, air pollution has gone to such a level that whether you are a smoker or a nonsmoker doesn’t matter.”
A Growing Concern in India
India is one of the worst countries for increasing pollution. Major cities like Ahmedabad, Mumbai, and Delhi often record an unsafe air quality index. Industrial emissions, car exhausts, and biomass combustion have increased respiratory and cancer disease cases. The fine particulate matter, mainly from vehicles, industrial activities, and dust from construction materials, enters the lungs, causes further inflammation, and increases the chances of oncogenic changes. With a fast-growing urban population and little emission control, the scenario demands emergency action through stricter laws, public awareness, and robust healthcare infrastructure to reduce its effects.
Early Detection Is Important
Symptoms most often common to lung cancer- persistent coughing, chest pain, and dyspnea- often coincide with symptoms of other respiratory conditions. Shalby Hospital explains how early diagnosis is significant: High-tech diagnostic imaging, such as low-dose computed tomography, can improve the prognosis of patients. Advanced diagnostics such as LDCT scans allow improving patients’ survival chances.
Taking Action
While it is great to support clean air initiatives, personally taking action matters the most, recommends Dr. Sudhir Palsaniya, Consultant Medical Oncologist, Shalby Jaipur.
- Reduce outdoor activities during periods of pollution.
- Using air purifiers indoors.
- Advocate for stringent emission control and sustainable development in cities.
At Shalby Hospital, we dreamed of an awareness for air pollution and its association with lung cancer. We continue to strive to reduce the burden of disease with advanced diagnostic tools and excellent care.
