| | RSNA: Mediastinal Masses Seen Often in Lung Cancer Screening; Most Benign (Site not responding. Last check: 2007-11-04) |
 | | CHICAGO, IL -- November 28, 2004 -- Mediastinal masses appear frequently in computerized tomography (CT) screening of persons with early lung cancer -- but while those asymptomatic lesions may appear alarming to clinicians, researchers say the smaller masses can be treated conservatively and should not excised routinely. |
 | | The researchers reviewed all 9,286 baseline CT scans of persons enrolled in the Early Lung Cancer Action Project (ELCAT) and the New York ELCAT as well as 9,992 annual repeat screenings. |
 | | Five thymic lesions greater that 2 centimeters in size were excised, and one was determined to be esophageal cancer. |
