CTC is available via the NHS at St Mark’s Hospital if your hospital or doctor feels that your symptoms or problems may potentially be due to cancer of the large bowel, or they would like to exclude this condition. Please speak to your doctor who will advise you if this is appropriate, and if so they can submit a referral to our service.
