What are the risk factors for lung cancer

Risk factors for lung cancer include long-term smoking, smoking up to a pack a day, smoking for more than 20 years, or smoking history for more than 30 years, or patients who have quit smoking for less than 15 years, and are older than 45 years old. Risk factors for lung cancer are as follows: There are two types of smoking, one is active smoking and the other is passive smoking. Active smoking means that the number of cigarettes smoked by the patient every day multiplied by the number of years of smoking is greater than 400, which will lead to a high incidence of lung cancer. Smoking is a high-risk factor for lung cancer. The amphetamines and nitrosamines in it are highly carcinogenic.
