Genetics: the study of inherited genes.
Haemorrhoids(piles): enlargement of the normal spongy blood filled cushions in the wall of the anus.
Hemicolectomy: surgical removal of about half of the colon with subsequent joining of the remaining colon.
Histopathology: the examination of tissue from the body under a microscope to spot the signs and characteristics of disease.
Ileocaecal valve: the valve at the junction of the small bowel and large bowel which controls the back flow of waste products.
Ileostomy: an opening into the ileum, part of the small intestine, from the outside of the body. An ileostomy provides a new exit for waste material.

Key Worker: a Professional, who with patient consent and agreement, takes a key role in co-ordinating the patients care and promoting continuity, ensuring the patient knows who to access for information and advice.
Laparoscopic Surgery: commonly called ‘keyhole surgery’. Several small incisions are made in the abdomen allowing a laparoscope (a small viewing camera) and specialised surgical instruments to view and operate on the tumour.
Laparotomy (open surgery): a surgical incision into the abdominal cavity to examine abdominal organs.
Large bowel: the colon and rectum.
Liver Biopsy: a medical procedure to obtain a small piece of liver tissue for diagnostic testing.

Malignant: a cancerous tumour which can invade and destroy surrounding tissue and spread to other sites in the body.
Margin: used in medical terms to describe a healthy section of tissue surrounding a tumour.
Melaena: black tarry faeces (stool) due to the presence of partly digested blood from higher up the digestive tract.
