Lung cancer in smokers versus non-smokers shows different genetic mutations

A group of scientists at B.C. Cancer Agency have found that lung cancers in smokers have different genetic mutations and look different than lung cancer in non-smokers. According to senior scientist at the BC Cancer Agency Research Centre Wan Lam, this finding is significant because it means that from now on, research, treatments and diagnostics should be tailored to the distinct genetic variations in the different lung cancers instead of expecting that a one-size fits all approach will work. He said, “At the current time, treatment does not distinguish between these different types. The subtypes are all grouped together. But with this work, we are beginning to tease out the subtypes.” The study was presented Tuesday at a conference in Philadelphia of the American Association of Cancer Research.

Screening heavy smokers for lung cancer reduces chance of death, federal study finds

The Boston Globe: "Screening heavy smokers with sophisticated medical scanners modestly reduced their chance of dying from lung cancer, according to a federal study released yesterday that provides the first convincing evidence that testing could reduce the toll from the leading cause of cancer deaths. The preliminary findings from the National Cancer Institute were based on a gold-standard study that randomly assigned 53,000 current or former smokers without symptoms to be screened with a CT scanner or standard chest X-ray.
