Experts link cancer with air pollution, warn about quality of cities #IndiaNEWS #Health
Bengaluru: It is going from bad to worse when it comes to air quality in urban centres while scientific research has confirmed that sagging air conditions are causing cancer.
Dr Sandeep Nayak P, Director Department of Surgical Oncology and Robotic and Laparoscopic Surgery, Fortis Hospitals, Bengaluru, stated that air pollution as a cause of cancer has slowly been shifting to the centrestage over the past few years.
Speaking to IANS, he said: It is estimated that exposure to air pollution, second-hand smoke, radon, ultraviolet radiation, asbestos, certain chemicals and other pollutants causes over 10 per cent of all cancer cases in India including Bengaluru.
He explained that over the past decades evidence that air pollution is linked to a range of cancers has been mounting. In 2013, a group of international experts, working for the World Health Organisations International Agency for Research on Cancer (IARC), looked at the findings of all the research that was available and concluded that air pollution causes cancer in humans in particular, lung cancer.
But what do these experts mean by air pollution? The term is very broad and covers a host of nasties including minuscule particles, tiny fragments of metals and gases.
However, when it comes to cancer risk, research so far shows that tiny dust-like particles just millionths of a metre wide so called particulate matter, or PM are the main culprits. In particular, the smallest particles less than 2. 5 millionths of a metre across, known as PM2. 5 appear to be behind lung cancers caused by pollution, he said.
These are chiefly found in emissions from diesel engines something IARC has ruled causes cancer in humans. The current research published in Lancet has tried to explain how PM2. 5 may cause cancer by causing inflammatory reactions and thus leading to cancer causing mutation, he stated.
Actor and environmentalist Suresh Heblikar explained that our country hasnt yet learned to build mega cities. We are building metropolitan cities like Bengaluru, Chennai, Pune, and Hyderabad. We have destroyed and wiped out many lakes. We have created housing layouts, bus stands and industrial, shopping layouts and commercial establishments. How can a city be built like that?
Bengaluru was the most beautiful city of India. It is completely wiped out because people are just making money in the name of smart city, he says.
Heblikar stated that we have to understand what kind of people are living in this country. We have more than 40 crore people living below the poverty line, five to six crore people totally unemployed and there is a minister who says he wants to build roads which can be compared to American roads.
