Cancer Society Endorses Virtual Colonoscopies

The American Cancer Society and other health groups have decided to recommend the use of virtual colonoscopies for detection of colorectal cancer, reports the New York Times. This comes after new studies showed that the procedure, which involves undergoing a CT scan to look for abnormal growths, is more effective than thought. The groups also endorsed the use of a test that examines a stool sample for DNA that would indicate abnormal DNA associated with cancer.
