Bad news this morning for former smokers who think they're out of the woods for lung cancer because they've quit lighting up.
The BC cancer agency says 50-percent of new lung cancer cases are in former smokers as opposed to those who still partake in the habit and they now have a new study, which could explain why.
Researchers have found some former smokers are still susceptible to lung cancer even years after they've quit because of gene damage.
The study finds in former smokers, some genes return to normal levels, while others appear to be permanently damaged - including a number of genes never before associated with tobacco use.
It’s estimated nearly 2300 British Columbians will die of lung cancer this year alone.
