Screening and Interventional Clinical Trials

Screening should identify cancers at an early stage, before they are clinically evident. Treatment would therefore be more effective, surgery less disfiguring, and there would be a greater likelihood that the cancer will not have spread. To be valid, a screening tool must be easy, convenient, cost-effective, widely available and safe, and it must show a benefit for the participant. With NCI support, the American College of Radiology Imaging Network (ACRIN) has conducted a number of Screening and Interventional Clinical Trials.
