A decision of how to treat a patient's cancer will be made at a specialised colorectal multidisciplinary meeting. Treatments are dependent upon the size, cell type and position of the cancer.

Before patients begin treatment,  a doctor will discuss with them the type of treatment they are to have along with the benefits and risks.

Before a paient begins their treament, they will be asked to sign a consent form. This is to ensure they understand the benefits and the risks of their chosen treatment type. For information on consent, please follow the link.

For more information on the various types of treatment and the consent process, please follow one of the links below: 


Surgery involves a hospital stay and takes place under general anaesthetic. Patients will have surgery in the Belfast City Hospital.  Click on the links for more information on types of surgery for colon cancer and rectal cancer.


Patients coming to Belfast City Hospital or Royal Victoria Hospital for surgery may be asked to come up to meet one of our medical team for a pre-assessment appointment in the Outpatients Department before surgery to ensure they are fit and safe for surgery.  In some cases patients are asked to have an anaesthetic assessment.  Most patients are admitted on the morning of their surgery but some may be admitted the day before.
