[An attempt to rationalize adverse health effects following tobacco smoking]

Statistics concerning tobacco smoking confronted with cancer epidemiology indicates that only a minority of smokers develops terminal cancer. To much extent it could be explained by genetic polymorphism responsible for a variable risk to develop cancer and its further progression. Then, a comparative analysis of the data concerning cancer deaths regarding a decline of smoking in developed countries unravels other factors previously not considered to represent carcinogenic agents. Human papilloma virus (HPV) could serve as an example of such agent exerting adverse health effects once attributed only to tobacco.
