“The regimen of screening determines how early the cancer is diagnosed. This is critical, as it provides the opportunity for earlier treatment which can be curative,” said NY-ELCAP principal investigator Claudia I. Henschke, Ph.D., M.D., professor of radiology at Weill Cornell Medical College and chief of the divisions of chest imaging and health care policy and technology assessment at New York-Presbyterian Hospital/Weill Cornell Medical Center in New York City. “Following the appropriate regimen also markedly decreases unnecessary work-up and biopsies,” she added.
