Cancer can strike even after the first cigarette

LONDON - very first cigarette can cause cancer in the body, BBC. 

This indicates an experiment conducted by the National Institute for Cancer Research in the U.S.. 

He analyzed blood samples from 12 patients smokers. 

Even after the first inhalation of tobacco smoke are formed substances directly causing tumor - polycyclic aromatic hydrocarbons. 

They are contained in cigarettes and smoking in the smoke passes, becoming to another chemical compound. This in turn damage DNA and cause cancer directly. 

The whole process from intake of smoke to breach the integrity of DNA of humans takes 15 to 30 minutes. 

The study was unique because for the first time an analysis of the metabolism of polycyclic aromatic hydrocarbons inhaled in cigarette smoke, without taking into account other factors such as food or dirty air. This is a comment to the BBC by Professor Stephen Heht the University of Minnesota. 

The result is a serious warning to anyone decided to encroach on cigarettes - the cancer can not come after 30 years of smoke and extinguished half an hour after the first cigarette in your life.
