Do smokers know that they will get lung cancer?

Do smokers know that they are at a higher risk of developing lung cancer?
Even though smokers are at a higher risk of developing lung cancer, it should be emphasized that, certain individuals have more active DNA repair genes, which could play a protective role against cancer even in chronic smokers. However, the toxicity of the cigarette smoke could significantly damage the DNA, leading to cancer in otherwise healthy cells.

It is tough to say whether smokers in India know that they will get lung cancer. It is important to understand that smoking does not always cause lung cancer. Smoking is a widely studied risk factor which researchers are sure about. However, there is a possibility of other factors that contribute to lung cancer. The Indian government has run many anti-tobacco programs to make smokers aware of lung cancer. The most common ones are warning labels on the packaging of tobacco products and warning snippets before a movie starts in a movie hall.

An article has discussed why some chain smokers never get lung cancer throughout their lives. One reason discussed was ‘DNA repair genes are more active among some individuals, which can protect against cancers arising, even when cigarettes are regularly smoked’. The article also states ‘While toxic tobacco smoke seems to trigger extra cell mutations in the lung, whether these mutations develop into tumours is dependent on how well the body can repair DNA or reduce DNA damage’. The study referred to in the article also found that the toxic changes that make healthy cells cancerous increase with age, ‘and among smokers, the DNA damage is even more significant’.
