COPD Heightens Deadly Lung Cancer Risk in Smokers

“Smokers who have chronic obstructive pulmonary disorder (COPD) may face nearly twice the risk of getting small cell lung cancer (SCLC)—the deadliest form of lung cancer—than smokers who don’t have COPD, according to a large worldwide study led by researchers at the Harvard T.H. Chan School of Public Health.

“The study was published online September 24, 2015 in EBioMedicine.

“The new study—the largest-ever epidemiologic study of SCLC—is the first to look at how much COPD, a progressive disease that makes it hard to breathe, increases smokers‘ risk of getting SCLC. Although it’s long been known that smoking is a major risk factor for lung cancer, the new study estimates the risk more precisely than before.”
