BEHAVIORAL: Stress reduction intervention
In addition to standard care, patients in the intervention group will receive a one-hour individually delivered programme administered once by a psychologist at least 3 days prior to surgery. This session aims to reduce stress and involves teaching relaxation and guided imagery exercises.

Summary
Brief summary
The purpose of this study is to investigate whether a stress reduction intervention prior to surgery can improve wound healing and recovery.The investigators hypothesise that patients who receive a psychological stress reduction intervention prior to surgery will report lower stress and higher perceived control, have lower stress hormones, better wound healing and better self-reported recovery than patients who receive standard care alone.
