Here is something that every smoker who argues against giving up smoking because even non smokers get lung cancer, should know about – smokers and non smokers get different kinds of lung cancer, according to a new study.
According to Kelsie Thu, Ph.D. candidates at the BC Cancer Research Center in Canada, there are twice as many DNA changes among tumors of non smokers than there are in the tumors of smokers.
The kinds of tumors are different because they follow different molecular pathways. Non smokers (people who have never smoked) could have other carcinogens that causes their tumors to have more DNA alterations and which encourages development of the cancer.
The implications of this study may result in different treatments being developed for the respective kinds of lung tumors.
There may now be a better understanding of the biology that underlies the lung cancer development and eventually result in better diagnosis and more focused treatment.
So if you are a smoker and often argue against giving up smoking by saying that non – smokers also get lung cancer and that not smoking is not a guarantee against getting lung cancer, then think again.
