Useful medical words
We have explained some of the medical words that you may hear when you are finding out about pancreatic cancer and how it is treated. You may also find the diagram of the pancreas and surrounding organs helpful.
Find words beginning with:
Once your food has been broken down, the nutrients are absorbed into the blood so that they can be used by the body. Read more about diet and digestion.
Adjuvant treatment is given alongside or after the main treatment. This may be adjuvant chemotherapy or radiotherapy that is given after surgery. Or it may be other medicines that are given alongside painkillers to help manage any pain.
Advanced pancreatic cancer
Advanced pancreatic cancer is cancer that has spread from the pancreas to other parts of the body, such as the lungs or liver. It is also known as metastatic cancer. It is not possible to remove advanced pancreatic cancer with surgery.
Ampulla of Vater
The Ampulla of Vater is the area where the pancreatic duct and the bile duct meet at the duodenum. This is also known as the hepatopancreatic ampulla. The Ampulla of Vater is labelled on our diagram of the pancreas and surrounding organs.
An analgesic is a medicine that relieves pain. Read more about pancreatic cancer and pain.
Ascites is a build-up of fluid in the tummy that may cause swelling, and you may feel full up quicker when you eat. It can also cause pain and discomfort. Read more about ascites and how it is managed.
Bile is a fluid which helps digestion. It is produced by the liver and stored in the gall bladder.
The bile duct is a tube that carries bile from the liver to the duodenum (small intestine).
Bilirubin is a yellow substance that is found in bile. It is the waste product of the normal break down of old red blood cells. If there is a build-up of bilirubin in the blood, you may develop jaundice.
A biopsy is a test that removes small tissue samples to examine under a microscope. A biopsy is the only way of being absolutely certain that you have pancreatic cancer. Read more about a biopsy.
Borderline resectable pancreatic cancer
Borderline resectable pancreatic cancer is cancer that has grown very close to the major blood vessels near the pancreas. It may be possible to remove the cancer, but it depends which blood vessels are affected and how far the cancer has grown.
If pancreatic cancer is blocking the bile duct or the duodenum, bypass surgery may be used to relieve the blockage. This can treat symptoms such as jaundice or being sick.
Cachexia is a loss of fat and muscle in people with long term illnesses, such as cancer.
Coeliac plexus nerve block
A nerve block is a treatment that blocks nerves from sending messages to the brain. It can be used to treat pancreatic cancer pain. You may be able to have a nerve block in the coeliac plexus, which is a bundle of nerves behind the pancreas.

Diarrhoea is runny poo. Read more about changes to your bowel habits.
Your diet is the food you eat. When we talk about symptoms or problems around diet, we mean problems that can affect your eating and digestion. We are not talking about the kind of diet people often go on to help them lose weight. Read more about diet and pancreatic cancer.
A dietitian is a health professional who provides expert advice about diet and nutrition, including how to manage the dietary symptoms of pancreatic cancer.
Digestion is what your body does to break down your food to get the nutrients out of it.
The duodenum is the first part of the small intestines. It absorbs nutrients and water from food that is passing out of the stomach.
Enzymes are substances that are made by different parts of the body, including the pancreas. Different types of enzymes have different roles in the body. Pancreatic enzymes help break down food.
Endoscopic retrograde cholangio-pancreatography (ERCP)
An ERCP is a test used to diagnose problems with the pancreas. It is used if your bile duct is blocked, to put in a small tube called a stent to relieve the blockage. Read more about an ERCP and what it involves.
Endoscopic ultrasound scan (EUS)
An EUS is a test used to diagnose pancreatic cancer. A thin, flexible tube (called an endoscope) is passed through your mouth and down into your stomach. The tube has a light at the end and a small ultrasound probe to create pictures of the pancreas. Read more about an EUS and what it involves.
This scan combines a CT scan with a PET (positron emission tomography) scan to build up a clearer picture of the cancer and how it is behaving. It can be used to learn more about the stage of the cancer and how best to treat it. Read more about this scan and what it involves.
A gastroenterologist is a specialist in diseases and disorders of the digestive system, including the stomach, intestines, liver and pancreas.
Genes carry the information that controls our growth and how our bodies work. Occasionally, there may be changes in genes which means that someone is more likely to get a disease. This type of change in a gene is often called a fault or mutation.
Glucose is the sugar found in foods and drinks. Our body turns all carbohydrates that we eat into glucose, and uses it as energy.
Hepatobiliary is a term that covers the liver, gall bladder and bile ducts. These are very close to the pancreas, and hepatobiliary (HPB) doctors and nurses may specialise in treating pancreatic diseases as well.
Pancreatitis is an inflammation of the pancreas. Hereditary pancreatitis is a rare type of pancreatitis that runs in families. People with hereditary pancreatitis have a much higher risk of developing pancreatic cancer.
Hormones are chemical messages that are made by your body. They are carried in your blood and affect different processes in your body.
Insulin is a hormone that is made by the pancreas. It helps to control blood sugar (glucose) levels.
A laparoscopy is a small operation that is sometimes used to confirm a diagnosis of pancreatic cancer, and to check whether the cancer can be removed by surgery. Read more about a laparoscopy.
Localised pancreatic cancer
Localised pancreatic cancer is cancer that is contained in the pancreas. It is the earliest stage of pancreatic cancer and it is possible to remove the cancer with surgery. It is also known as early or resectable pancreatic cancer.
Locally advanced pancreatic cancer
Locally advanced pancreatic cancer is cancer that has spread to structures around the pancreas, such as blood vessels, the stomach or the spleen.
Lymph nodes are small oval structures throughout the body that contain lymph fluid. They are part of the immune system.
An MRCP is a type of MRI scan. It gives a clear picture of the bile duct or pancreatic duct, and any blockages in them. Read more about an MRCP.

Palliative care helps people live as well as possible for as long as possible if their cancer can’t be cured. It manages complex symptoms such as pain, as well as providing emotional, practical and spiritual support. It’s not just for people in the final stages of life.
The pancreatic duct is the small tube that carries pancreatic juices (which contain pancreatic enzymes), from the pancreas to the duodenum.
Pancreatic enzyme replacement therapy (PERT)
PERT is used if the pancreas isn’t producing enough enzymes to digest your food. It involves taking pancreatic enzyme supplements to help break down food.
Pathology is an examination of tissue and cells under a microscope. A pathologist is a doctor specialising in pathology.
This is a type of surgery to remove pancreatic cancer. The procedure is similar to the Whipple’s operation, but none of the stomach is removed. Read more about a pylorus-preserving pancreaticoduodenectomy.
A radiologist is a doctor specialising in using x-rays to diagnose and treat disease.
Radiotherapy uses high-energy x-rays (radiation) to destroy cancer cells.

Resectable pancreatic cancer is cancer that is contained in the pancreas and can be removed by surgery. It is also known as early or localised pancreatic cancer.
The small intestine is part of the bowel, where food is digested and absorbed. The duodenum is the first part of the small intestine.
The stage of cancer describes the size of the cancer and whether it has spread. The stage of pancreatic cancer is used to decide what the best treatment option is.
Steatorrhoea is caused by fat in poo. Poo may be large, pale, look oily, smell horrible, and be difficult to flush down the toilet. It can be a symptom of pancreatic cancer.
A stent is a small, hollow tube. If you have pancreatic cancer you may have a stent put into your bile duct (a biliary stent) or your duodenum (a duodenal stent) to relieve any blockages. This can help relieve symptoms of jaundice or sickness.
Stools is another word for poo. It is also called faeces or bowel motions.
Supportive care teams provide similar services to palliative care teams. They help people who have cancer that can’t be cured lived as well as possible for as long as possible. They help people to cope with their condition and its treatment.
