A new research study has thrown up startling possibilities as far as lung cancer is concerned. The carcinoma which invades cigarette smokers seems to be quite different from the cancer that affects people who refrain from the intake of nicotine.
The nature of the tumors in lung cancers which develop in smokers and non smokers vary widely discovered the scientists. The non smoker type of lung cancer occurs more commonly in women particularly those hailing from Asia. The tumors that develop within the lungs of the smokers have been found to carry a particular type of mutation while the ones in non smokers carry a completely different type altogether.
The study results also show that the process of developing lung cancer in non smokers is a long drawn path which becomes considerably shorter for the ones habituated to smoking. Researchers also feel that the path for the smokers may deviate considerably from the known way and follow an entirely different route altogether.
The study got underway with Kelsie L. Thu associated with the BC Cancer Research Center, Vancouver, Canada and his colleagues analyzing the genetic features of people diagnosed with lung cancers. There were 30 participants in the study who had never smoked in their lives while 39 were smokers with 14 other participants belonging to the group of former smokers.
The researchers confirmed that while there had been a number of similarities in the nature of the lung cancers, the genetic changes differed quite a bit for the two prominent groups comprising of smokers and non smokers. Thu and associates also discovered the fact that the non smokers had many more genetic changes accumulated in their lungs than the smokers. The ones who had never smoked should be considered as a separate group altogether stated Thu in the news release. The most interesting aspect of the study proved to be the similarity between the lung cancer tumors of non smokers and the tumors of those who had given up smoking.
The results of the study were presented by Kelsie L. Thu at the American Association for Cancer Research’s Frontiers during the Cancer Prevention Research Conference held between Nov. 7-10 at Philadelphia.
