Potential participants (patients with colorectal cancer offered an operation) will be highlighted from the Derbyshire NHS trusts colorectal multidisciplinary team meeting. All patients who fulfil entry requirements will be seen by the research fellow after their outpatient meeting with their particular surgeon (if they agree). Information packs containing details of the study (information sheet and consent form) will be given and any questions answered. Patients will be allowed to take the packs away with them and decide whether they would be keen to participate. Interested patients will be consented by the research fellow during their subsequent pre-operative clinic appointment.
