Answer

Because not all smokers develop lung cancer and not all lung cancer patients have a history of smoking, other factors (eg, genetic susceptibility [see Pathophysiology], arsenic exposure, radiation exposure, and other environmental carcinogens [13]  also play a causative role, either independently or in conjunction with smoking. Genetic factors probably contribute in all populations, but the contribution of other factors is population-specific.

A study by Bagnardi et al determined that alcohol is not an independent factor in the etiology of lung cancer. [14]
