Question: Tobacco causing immediate cancer - is it possible?


 phillyeagles - Fri Dec 08, 2006 5:56 pm

I received a response previously to my personal situation but I was just wondering in general is it possible to develop cancer as an immediate (within a week) reaction to a tobacco product. Are you at immediate health risk if you use a tobacco product only once or twice?

User avatar Hello,

A person's increased risk of contracting disease is directly proportional to the length of time that a person continues to smoke as well as the amount smoked.

For example, the risk for lung cancer that results from smoking cigarettes is quantified in “pack-years.” One in seven people who smoke more than two packs per day die from lung cancer. The incidence of death from lung cancer starts increasing above the incidence from the nonsmoking population at 10 pack-years.

However, if someone stops smoking, then these chances gradually decrease as the damage to their body is repaired. This approaches, but does not quite reach, that of nonsmokers after 15 years of abstinence for those who smoked for less than 20 years.

Another thing is that cancer is made up of individual cancer cells. For cancer to develop into a clinically apparant cancer it has to have been present for months if not years in some conditions.

So the simple answer is no that's not possible.

Best regards,
