Urgent Suspected Cancer: Lower GI

NCL Wide
Under Review — this page was due to be reviewed by Friday, 20 March 2026. The information shown here may be outdated.

When making an urgent suspected cancer (USC) referral (previously known as two-week waits or 2WW), please ensure your patient understands that they have been referred on a suspected cancer pathway and that they should make themselves available for diagnostic tests and outpatient appointments for the next 28 days.


Guidance for referring patients for suspected lower gastro-intestinal cancer, in summary is:

  • GPs should continue to refer patients with suspected lower gastro-intestinal (GI) cancer on the current urgent suspected cancer (USC) form.
  • GPs should undertake faecal immunochemical (FIT) testing in symptomatic patients in line with NICE guidelines. Exceptions are anal mass, rectal mass or anal ulceration; these patients should be referred directly (without a FIT test) onto the suspected lower GI cancer pathway.
  • Patients who have had a negative or normal bowel screening result and present to their GP practice with possible suspected lower GI cancer symptoms should have a FIT test in primary care.

For further detail on FIT see the FIT section on the Right Test Right Time page.
