Folate and colo-rectal cancer risk.

The UK Food Standards Agency convened a group of expert scientists to review current research investigating folate and colo-rectal cancer risk. The workshop aimed to examine current research and establish research priorities. The timing of folate exposure with respect to carcinogenesis, as well as the dose and form of folate, were considered key issues for future research. Also, the need to study further the influence of genetically defined subgroups was highlighted for future research.
