“In order to reduce the risk of lung cancer, we should stop smoking, avoid cigarette smoke and pollution. Moreover, the people who are at risk for lung cancer should undergo the cancer screening test annually, especially people aged over 55 years old who smoke cigarette around a pack of cigarettes a day for over 30 years. They should undergo the lung cancer screening test with Low-dose computerized tomography (LDCT) which is more sophisticated than the normal one. The earlier you know, the better.” said, Dr. Thanate.

There are long term effects on health as well such as Chronic bronchitis, deteriorated lung function, and increased risk of lung cancer because PM 2.5 Dust is one of the carcinogens; especially in patients who have respiratory problems and heart diseases. Children and elderly are they are more sensitive to the dust and they might be more susceptible than others.”  said, Dr.Yada.
