This came across my 'netscape' main page of my computer,stop smoking, figured I'd share in case you might find it interesting.Gene May Predict Lung Cancer in SmokersBy Marrecca FioreScientists say they’ve discovered a gene they believe sets off a series of pre-cancerous changes that could help predict which smokers will develop lung cancer.They also say a natural substance may be able to reverse the chain-reaction before it develops into full-blown cancer.The gene in question, P13K,quit smoking, affects the pathway of other genes and may activate the genetic changes that lead to lung cancer, Andrea Bild of the University of Utah, Avram Spira of Boston University and other colleagues report in their study published in the journal “Science Translational Medicine.”Dr. Len Horovitz, a pulmonary specialist at Lenox Hill Hospital in New York City, told AOL Health the study’s findings will allow doctors to look for dysplasia, or the abnormal growth of cells, which is often leads to cancer.“Just the fact that you can identify the dysplasia is an enticing reason to test smokers for these genetic changes and try to get them to stop smoking before they develop lung cancer,” he said.Lung cancer, which killed nearly 160,000 Americans last year, is the leading cause of cancer deaths. And smoking is the No. 1 cause of lung cancer -- although not all smokers will get it.'Even for people who have stopped smoking, there's a significant risk of cancer down the road, and it would be nice to identify which patients are really at risk,' Duke University lung cancer specialist Dr. Neal Ready told the Associated Press.'To have some sort of molecular test that would identify those patients would be very useful.'Learn more about the study in the video below.
