“Around 80-90% of lung cancers are associated with a history of cigarette smoking. The other 10-20%, however, can be related to a family history of lung cancer (for example, inherited mutations) or exposures to second-hand smoke, radon gas, occupational exposures to cancer-causing agents and indoor and outdoor air pollution,” Dr. Flora mentioned.

Fable #2: When you smoke, there is no such thing as a use quitting

Truth: It is by no means too late to stop, optimistic outcomes are nearly instant.

As soon as an individual stops smoking, the physique exhibits instant adjustments. Inside simply 20 minutes of quitting, each blood strain and coronary heart charge begin to lower, and inside a number of days, carbon monoxide ranges return to regular. Lung operate improves between two weeks and three months of quitting.

“While it is true that the risk of developing lung cancer after quitting smoking still exists, the added risk of developing lung cancer drops by half after 10-15 years of quitting.

Nevertheless, since screening checks carry a specific amount of danger related to radiation, they’re sometimes reserved for individuals at excessive danger.

“As such, there is a valid concern from patients regarding radiation exposure leading to cancer. This is why we do not screen healthy, young, non-smokers. Those who are at high risk (aged 50-80 years, with a 20-pack-year smoking history, and are current smokers or quit within the past 15 years) are at a significantly higher risk of dying from lung cancer than they are from developing cancer as a result of radiation,” Dr. Flora added.
