1. You should quit smoking
as soon as possible because your risk of developing lung cancer
, especially the NSCLC
(Non Small Cell Lung Carcinoma) is already double that of a normal person because you have a positive family history.
2. For a normal person without any additional environmental and genetic predisposition, the risk of developing lung cancer equates to fifty pack years of smoking (smoking a pack of cigarettes per day for fifty years).
3. Lung cancer can also happen to people who don't smoke. However, early detection is the key to successful treatment.
