Pancreatic Cancer
Tests and diagnosis of pancreatic cancer
People told us about their experiences with getting tests to diagnose pancreatic cancer. The symptoms of pancreatic cancer vary and can be caused by many other things, which can make it hard for doctors to spot and diagnose it. If you have symptoms, your GP may refer you to the hospital for tests.
These tests might include:
- Blood tests
- Ultrasound scans (sonogram) of the tummy (abdomen)
- Computer Tomography (CT scan)
- Magnetic Resonance Imaging (MRI)
- Magnetic Resonance Cholangiopancreatography (MRCP; a type of MRI that can give clearer pictures)
- Fluorodeoxyglucose-Positron Emission Tomography/CT (FDGPET/CT; an imaging test that uses a radiotracer to highlight metabolically active areas of the body such as tumours)
- Endoscopy (ERCP)*
- Endoscopic ultrasound (EUS)
- Endoscopic retrograde cholangio pancreatography (ERCP)*
- Colonoscopy
- Biopsy*
*See 'Endoscopy, ERCP and biopsy' for more information.
Blood tests
When a doctor sees a person who presents with symptoms that could be pancreatic cancer, they usually order blood tests. These tests might be to check the liver function and blood sugar levels.
Some people we interviewed had blood tests which had all come back completely normal. Other people's results had been abnormal.
Hamish told his GP about his symptoms. After a blood test the GP told Hamish that he probably had pancreatic cancer.

Colonoscopy
If your symptoms include changes in bowel habit (e.g., loose poo), the doctor may want to test the poo for abnormal enzymes or blood.
They may suggest a colonoscopy (a diagnostic test using a flexible tube with a camera (an endoscope) to look into the large intestine and the lower part of the small intestine) or a sigmoidoscopy (a diagnostic test using an endoscope to look into the lower part of the large intestine (the sigmoid colon) to check for bowel abnormalities.

Ultrasound scan (sonogram)
An ultrasound scan is usually one of the first investigations to be done. The ultrasound scan is painless. It uses sound waves to create images of the inside of the body. These scans are similar to those that pregnant women have to monitor their unborn baby.
Some people had to wait for a few weeks to have scans in NHS hospitals or clinics. One man was told that he had to wait 3 weeks to have a scan locally. However, he could drive 30 miles and have the scan done the next week in a private clinic paid for by the NHS.
Richard described what his ultrasound scan was like. He was disappointed that he had to wait so long after it for a CT scan.

The behaviour of the person doing the scan (the radiographer) made some people aware that something was wrong. Anthony’s wife told him that the radiographers had been chatty at first, but then suddenly went silent.
At Ann's ultrasound scan the radiographer told her that her bile duct and pancreatic duct were dilated.

And he [the gastro-enterologist] said, “And then you’ve got an ultrasound in two days’ time.” So I went for the ultrasound and that’s when I really realised what was going on. Because I went for the ultrasound expecting it to be pretty normal. And they did the ultrasound, and the, the radiographer who was doing it kept going backwards and forwards, backward and forwards over the top part of my abdomen. And so eventually I said, “Is there a problem?” And she said, “Actually, the bile duct and the pancreatic duct are dilated. And I don’t know why.” And I just knew then that I must have pancreatic cancer. Which I didn’t want to think about it really, because I know it’s a horrible cancer to have. And so I was pretty shaken by that really.
Alison was told she would have to wait 4 weeks to have an NHS scan, so she chose a private referral to a consultant surgeon. She saw him within a few days and had a scan the next morning. Her husband’s private medical insurance paid for the scan.
Computer Tomography (CT) Scan
If an ultrasound shows an abnormality the doctor usually orders a CT scan or other scans. People we interviewed had at least one CT scan after their ultrasound. CT scans use X-rays to create images of the inside of the body that are far more detailed than ordinary X-ray images.
During the scan the person lies on a bed. The bed then moves slowly backwards and forwards to allow the scanner, which is shaped like a large donut, to take pictures of the inside of the body.
Before the CT scan some people were given an aniseed flavoured drink to help identify the stomach and small intestine in the scan. Some said that they didn't like the drink. During the scan the radiographer usually injects what is called a contrast dye into an arm vein to make organs and abnormalities more visible. The scan does not hurt.
Helen had several CT scans. It felt strange when the radiographer injected dye into her arm.

I don’t know what else to say about a CT scan really. It’s, from a patient’s perspective it’s just, it’s just the dye that they inject you with, which helps all your insides to stand out clearly on the scan. That’s not a problem. You don’t really feel it, apart from it can give you a sensation of warmth flooding your body. And it can also make you feel as though you’re passing urine. It’s, it’s a very strange feeling. But it’s fine. It doesn’t hurt. It doesn’t affect you. You don’t feel it afterwards. It’s literally a few seconds of warmth and then it’s gone. And it’s just like a big doughnut, the CT scanner, that you pass through on a table. It’s, you know, it’s not frightening. Well, I don’t think it’s frightening. Very simple.
Tony had to drink a litre of fluid before his CT scan. The radiographer also injected a dye into his arm. The scan was painless.

Vicky said she had dreaded having the needle put into a vein, and one day the dye leaked out of a vein into the surrounding tissue (called contrast extravasation), which she found ‘excruciatingly painful’. Contrast extravasation can cause pain, discomfort, a stinging feeling, swelling, and bruising at the injection site and in the arm or hand that typically wears off after 30 minutes (NHS, September 2024).
Magnetic Resonance Imaging (MRI)
A few people we interviewed also had Magnetic Resonance Imaging (MRI) scans. These scans use strong magnetic fields and radio waves to make a detailed picture of the inside of your body. The scanner is a large tube with a series of powerful magnets. The person lies still on a bed that moves into the ‘tube’ during the scan.
Donna had had MRI scans before and ‘knew there was nothing to worry about’ for the scan itself. May said ‘the staff had put her at ease’. Some people found MRI noisy and rather frightening.
Richard found the MRI scan 'slightly alarming' because it was noisy but it wasn't painful. He had a 'dye' injected into his arm.

Fred found the MRI scan 'very frightening' and claustrophobic. He found the CT scan 'scary' too.

Positron Emission Tomography (PET)
Positron Emission Tomography (PET) scans can give a clearer picture of the cancer. These scans produce 3-D images of the inside of the body and can highlight how certain functions of the body are working rather than only showing what the parts inside the body look like.
PET scans work by highlighting the radiation given off by a substance injected into the body (a radiotracer) to see how it moves through the body and where any build up or abnormalities occur. The scan is done with the person lying flat and still on a bed that is moved into the scanner, which is large and shaped like a cylinder.
PET scans may also be done in combination with CT scans (called a PET-CT scan) and MRI scans (called a PET-MRI scan) to produce even more detailed images (NHS, 17 March 2021).
One man needed a PET scan before starting CyberKnife treatment to make sure his cancer had not spread to other organs. Others had a PET scan when they developed symptoms which might have been a sign of the cancer coming back.
Laparoscopy
A few people said that they’d had a laparoscopy (keyhole surgery) before they'd had major surgery, such as a Whipple’s procedure*.
The laparoscopy was done so that their surgeon could make sure that the cancer hadn't spread to other organs. Laparoscopy is an operation using a camera which goes in through one or more small incisions. It is performed under general anaesthetic.
Most people said that this simple operation went smoothly, though Audrey recalled that when she awoke from the anaesthetic she was in a lot of pain. She thought this might have been due to the gas that the surgeon had put into her abdomen to help see all the organs clearly.
Lesley had a laparoscopy before her Whipple's operation to check that the cancer had not spread to other organs.

*A Whipple's procedure/operation (pancreaticoduodenectomy) is a surgery that removes the head of the pancreas, the first part of the small intestine, the lower end of the stomach, the gall bladder, part of the bile duct, and some nearby lymph nodes (Pancreatic Cancer UK, January 2024). See 'Surgery to remove pancreatic cancer'.
