More Evidence Backs Routine CT Scans For Early Lung Cancer DetectionSep-08-2013
Annual lung cancer screenings using low-dose CT scans can successfully detect malignant tumors before they can spread to other parts of the body, according to two new studies.
Yearly screenings with CT scans are more effective than regular chest X-rays in finding early stage cancers, according to a U.S. study that is part of the federally funded National Lung Screening Trial.
CT scans caught more early stage lung cancers than chest X-rays did during annual screenings over three years, the research team reported. What's more, the ability to accurately detect cancer improved year to year.
"When we're screening once a year every year we are finding early stage lung cancers that are potentially curable," said Dr. Caroline Chiles, a professor of radiology in the Comprehensive Cancer Center of Wake Forest Baptist Medical Center and a principal investigator for the national lung screening study. "We really start seeing benefit when someone stays in annual screening."
