According to a new study, U.S. researchers have identified a gene that can help answer why some people who do not smoke develop lung cancer.
www.news.pushpi.com reports that in the UK, around 10 percent of lung cancers develop in non-smokers. Cancer Research UK’s science information manager, Dr. Kat Arney said: “Smoking causes 90% of lung cancers, but there is still a significant number of non-smokers who develop the disease.”
Zimbio.com reports that the research was conducted by scanning the DNA samples of 754 people who had smoked less than 100 cigarettes in their lifetime. After considering chronic respiratory diseases, family history of lung cancer and inhalation of second-hand smoke, two sections of the genome were found to be the cause of lung cancer in non-smokers.
Researchers hope to get more information on GPC5 gene to develop new treatments. Cancer Research UK said more research was needed to know the exact reason why non-smokers develop lung cancer. News.bbc.co.uk quoted Dr. Kat Arney as saying: “These new results could help to explain why, but much more work needs to be done to understand exactly how these gene variations are linked to lung cancer risk.”
