Yee: What we found was that 63% of patients actually had a finding outside of the colon. Not all of those were significant. Nine percent had a significant finding. By that, what I mean is the finding actually led to an intervention. Either additional follow-up or actual surgery to have something removed.
Narrator: Yee says some of the findings they identified outside of the colon using virtual colonoscopy included lung cancers, kidney cancers and liver masses.
Yee: Because patients are not symptomatic for the problem that we have identified outside of the colon, we tend to identify disease outside of the colon at an earlier stage.
