Are screen-detected colorectal cancers associated with an improved outcome compared with stage-matched interval cancers?
The improved survival of screen-detected over interval cancers for stages C and D suggest that there may be a biological difference in the cancers in each group. Although lead-time bias may have a role, this may be related to a tumour's propensity to bleed and therefore may reflect detection through current screening tests.
