Cancer genes stay active in non-smokers, says study

Filed under: ,

If you used to smoke but do no any longer, did you know that genes that have been 'activated' by your past smoking habit remain on even long after you quit?

This conclusion comes from a new study that is being published today. Researchers analyzed gene activity in the respiratory tracts of 24 smokers, non-smokers and ex-smokers and came up with the suggestion that cancer-related genes just don't "reset" once a smoker stops smoking.

Although those quitters can breathe a sigh of relief (literally and figuratively), the propensity for lung cancer does not automatically diminish once you stop smoking, although it may decrease over time (years and years).

There are so many reasons to quit smoking these days, and this this is yet another good one, even though it may suggest otherwise.
