All other causes such as the environment are much less common in terms of numbers of cases. Even lung cancer risk from naturally occurring radon is very small compared with smoking tobacco. The cure rate of lung cancer remains very poor and is of five years’ survival rate only ten per cent.
Lung cancer kills more victims as breast cancer, prostate cancer and colon cancer. Until the first time the patient develops severe symptoms, such as chronic hoarseness of voice or cough up blood, it is usually too late for successful therapy.
But if the cancer is detected early, according to the American Cancer Society of survival rate of’47 of the most frequently performed X-ray examinations.

(Marijuana contains approximately ten times more tars as tobacco)
Up to 95 percent of all patients with lung cancer are, or were smokers. Passive smoking has also increased the risk of disease, although this is often disputed. From 30 to 40 years after the onset of smoking is the risk rises to 60 times higher than that of non-smokers.
