from a medical stand point..how long does it take to get lung cancer, some people smoke and their fine?

Answer 1

speaking not just for lung cancer......for cancer in general. development of cancer is affected by a lot of factors

1) genetics--presence of genes that predisposes to carcinogenesis vs genes that give you additional protection from carcinogenesis
2) family history
3) exposure to carcinogens, e.g. smoking
4) presence of co-morbid illnesses/conditions that predispose to carcinogenesis e.g. smoking plus working in an asbestos factory

there is no fixed period of exposure that predicts development of lung cancer after initiation of smoking, the best thing to do is still to stop smoking, which would not only decrease your risk of developing lung cancer but also decrease your risk of developing other lung diseases like chronic obstructive lung disease

Answer 2

There is no set time limit in developing cancer from smoking. Some people smoke all their life and never develop cancer but get emphysema.. Yul Brenner, John Wayne both died from lung cancer from smoking. So it varies. I smoked for 5 years and started getting short of breath and quit. Haven't smoked now in 8 years.

Answer 3

Would you cross the street in heavy traffic without looking both ways? this is what your doing with chances in cancer.
