environmental pollution is now a days gain widespread attention amongst

residents living in metro cities such as hazardous level of air pollution in National

Capital Delhi. It has tremendous adverse impact on human health and can induce

cancer as well.

Meet Dr. Sandeep Nayak, Director of Surgical Oncology, Robotic & Laparoscopy at Fortis Hospitals- Bangalore, who shares his view on environmental pollution and its adverse impact on human health with an interview with

A) What are the major carcinogens

elements that are present in the polluted environment i.e. polluted air or

contaminated water that can damage our health?


are many known and unknown chemicals that can damage us. More than the

chemicals the fine dust in the air that is inhaled can damage lungs. In 2013

outdoor air pollution was declared carcinogenic, as these are dust particles

that are one-millionth of a meter, which comes from vehicle fumes and

factories. The smallest of these particles called PM10 and PM2.5 are mainly

implicated in lung cancer. 1 in 10 case of lung cancers is due to air

pollution. However, it is important to remember that smoking is another big

cause of lung cancer. Drinking water has other concerns. Most of the risk is

due to arsenic and disinfection byproducts. These chemicals can cause multiple

kinds of cancers.

B) What type of cancers was typically

caused by industrial effluents and by air pollution?


research so far has proved that industrial effluents and air pollution can

cause lung cancer, skin cancer and urinary bladder cancer.

C) Air Pollution in a few major

cities in India is getting worse in the recent past? What precaution a common man can do to reduce

its impact on our day-to-day life?


of all, common man should own this as they are responsible for the pollution

and they should make attempts to bring down their carbon footprint. It is necessary that each of us should avoid

using the polluting vehicle, reduce the usage of cars, do not burn things, etc.

D) Do you suggest the air purifier,

which is being used in home, or offices can prevent from the adverse impact of

bad air quality?

Yes, they do help by filtering the most dangerous dust particles.

Common man should own this and should make attempts to bring down their carbon footprint- Dr. Sandeep Nayak

E) Is there any specific food habit

one must reduce to reduce the impact of carcinogens


consumption of fresh fruits and vegetables helps a lot in staying healthy.

However, it is essential that we should avoid ultra-processed food that can be

unhealthy for our body.

F) Lack of environmental awareness

results in epidemic across the country. Government is promoting Swachh Bharat

Abhiyan for cleanliness, how this initiative can be seen as a stepping-stone

for a healthy environment?


Bharat is mainly for hygiene while pollution is a broader topic than that. It

needs a major change in the attitude of people and materialism has to end. We

need to look at how to reduce our carbon footprint.
