Smoking and gene mutation , 2 year old who Smokes 40 Cigarettes Per Day

 Heavy smokers who get lung cancer may have tens of thousands of genetic mutations, US researchers said.

A team at Roche's biotechnology unit Genentech in California compared all the genetic changes in a single patient's lung tumor with healthy tissue from the patient, a 51-year-old man who had smoked an average of 25 cigarettes per day for 15 years before the tumor was removed.

What they found were as many as 50,000 genetic mutations. "Fifty thousand is a huge number. No one has ever reported such a high number," said Zemin Zhang of Genentech, whose findings appear in the journal Nature. "This is likely associated with the smoking history of the patient. It is very alarming," Zhang said in a telephone interview said on Wednesday.

Smoking is the biggest single cause of lung cancer, and studies suggest mutations occur with each cigarette smoked.

Zhang said the ratio between the number of cigarettes the person smoked before his tumor was removed and the number of mutations in the tumor suggest that for every three cigarettes he smoked, one genetic mutation occurred.

A recent  stunning youtube video showing a 2 year old boy who is addicted to nicotine has recently made the news...  To me its possibly the worst parenting in the world and this child will pay a heavy price soon....
