Rectal cancer occurs when abnormal cells grow out of control in your rectum.
If the tumour was small and had not spread, your doctor may have removed it during the colonoscopy. But you may need surgery to remove the cancer if the tumour was too big or had spread too far to be removed during a colonoscopy. If cancer has spread to another part of your body, such as the liver, you may need surgery or other treatments.
Treatment for rectal cancer may also include radiation therapy. Medicines that destroy cancer cells, such as chemotherapy or targeted therapy, may be used.
