"We are striving to find the earliest molecular changes that are induced by environmental stressors – in this case, smoking," said Renat Shaykhiev, M.D., Ph.D., assistant professor of genetic medicine at Weill Cornell...

Researchers have begun to identify which mutations and pathway changes lead to lung cancer in never-smokers – a first step in developing potential therapeutic targets. Never-smokers (defined as an individual who smoked fewer than 100 cigarettes in his or her lifetime) are estimated to account for 10 percent of lung cancer cases. However, in the past, researchers have not examined this patient population as extensively as they have studied patients with lung cancer who smoked,...
