Glycogen storage disease and liver tumours: what families should know | CION Cancer Clinics
Glycogen storage disease, especially type one, often causes benign liver lumps called adenomas from the teenage years onward. Most stay benign, but a few can turn into liver cancer, so they are watched with regular scans. This page explains which types carry the risk, how adenomas are followed, what makes a lump need a closer look, and where cancer care fits in. At CION Cancer Clinics, our specialists help you understand your own risk and plan regular liver checks that fit it.

The short answer
Does glycogen storage disease lead to liver tumours?
Some types do. People with glycogen storage disease, especially type one, often develop benign liver lumps called adenomas in their teens or adult years. Most adenomas stay benign, but a small number can change into liver cancer, which is why they are watched with regular scans.
What the condition is
Glycogen is the form in which the body stores sugar, mostly in the liver and muscles. In glycogen storage disease an inherited fault blocks one of the steps that stores or releases it. Sugar gets locked away in the liver, the liver swells, and the blood sugar can drop dangerously low between meals. Most families learn about it in early childhood, through a metabolic or child specialist.
Which tumours this page is about
This page is about lumps that start in the liver itself in someone with this condition: adenomas, and the rare hepatocellular carcinoma (HCC) that can arise from one or from a scarred liver. It is not about hepatoblastoma, a different cancer of young children, which has its own page on liver cancer in children.
An adenoma is not cancer. It is a reason to keep every follow-up scan you are given.Not all types alike
Which types of glycogen storage disease affect the liver most?
There are many types, named by number. The liver risk is very different from one to the next, so the type written on your report matters.
Type one
Also called von Gierke disease. This is the type most linked to liver adenomas. They usually appear from the teenage years onward, are often several in number, and can grow or bleed.
What the team watches
- New lumps on the scan
- A lump that grows or changes in look
- How well blood sugar is controlled
Type three
This type affects both the liver and the muscles. Adenomas occur less often than in type one, but some people develop scarring and cirrhosis in adult life, and HCC can arise in that scarred liver.
Type four
A rarer type that can scar the liver early in childhood. Children with severe liver scarring are usually cared for in specialist transplant programmes from a young age.
Muscle-only types
Several types affect only the muscles and cause weakness or cramps with exercise. They do not carry the same liver tumour risk, and this page mostly does not apply to them.
Not sure whether this applies to you?
Ask an oncologistKeeping watch
How are liver adenomas watched in glycogen storage disease?
Regular liver imaging
An ultrasound is the usual starting scan. Once adenomas are found, many teams move to MRI, which shows the lumps more clearly. CION arranges these scans through diagnostic partners and your metabolic doctor sets the interval.
Blood tests alongside
Liver tests and sometimes AFP, a tumour marker, are checked. AFP is often normal even when an adenoma changes, so a normal result does not replace the scan. Read more about why adenomas are watched.
Good metabolic control
Keeping blood sugar steady with the feeding plan your specialist and dietitian set appears to help. In some people adenomas shrink or stop growing when control improves. This is the part families can influence every day.
Review when a lump changes
A lump that grows, looks different or bleeds is reviewed by a liver team. If cancer is suspected, CION's tumour board looks at the scans and plans the next step with the surgical and hepatology teams.
Side by side
When is an adenoma just watched, and when does it need more?
Usually watched
Usually needs a closer look
Small lumps that stay the same on each scan
A lump that is growing between scans
Lumps that look typical of an adenoma on MRI
A lump whose appearance has changed
Steady blood sugar control
Sudden pain in the upper right belly, which can mean bleeding
Normal or unchanged AFP
A rising AFP, though a normal one does not rule out change

Commonly believed
What do families often believe about these liver lumps?
"A lump in the liver means cancer."
In this condition most liver lumps are adenomas, which are benign. The concern is that a few can change over time, so they are watched. Fear should lead to keeping scans, not to assuming the worst.
"Our child grew out of it, so no more scans are needed."
Low sugar spells often ease as children grow, but adenomas tend to appear in the teenage and adult years. Moving from a children's doctor to an adult doctor is exactly when follow-up most often gets lost.
"The diet only matters for blood sugar."
The feeding plan also seems to affect the liver. Better control has been linked with fewer and smaller adenomas in some people. Changing the plan should always be done with the specialist and dietitian.
"The parents passed on a bad gene, so it is their fault."
Both parents usually carry one silent copy without knowing. Nobody can choose the genes they pass on. Testing brothers and sisters, and genetic counselling before another pregnancy, is help, not blame.
Being straight with you
What this page cannot tell you
It cannot tell you whether a lump on your own scan is an adenoma or something else. Only the radiologist and liver team who have seen your images, ideally compared with the older ones, can say that. It also cannot set your scan interval, which depends on your type, your lumps and how they have behaved.
Who this does not apply to
If you have one of the muscle-only types, the liver tumour risk described here largely does not apply. If you have a single liver lump and no glycogen storage disease, the causes are different. The page on genetic conditions that raise liver cancer risk covers the wider group.
Where CION fits
Day-to-day care of glycogen storage disease belongs with a metabolic specialist. CION becomes involved when a lump is suspected of being cancer. The tumour board reviews the scans, and CION's surgical oncologists assess whether removal makes sense. Your team will tell you where any operation takes place. Ablation and liver transplant, where considered, are coordinated through partner and licensed transplant centres. Evidence on the best approach is thin, because the condition is rare.
Questions we are asked
Common questions about glycogen storage disease and liver tumours
Will every person with glycogen storage disease get liver tumours?
No. Adenomas are common in type one and less common in other types, and many people never have one. Of those who do, most never develop cancer. The aim of regular scans is to catch the rare change early, while it can still be treated.
How often should the liver be scanned?
That depends on your type, your age and whether adenomas have been found. Your metabolic specialist or liver doctor will set the interval. If you are an adult and nobody has told you, ask directly at your next visit and write the answer down.
Can an adenoma be removed?
Sometimes. A large, growing or bleeding adenoma, or one that looks as if it is changing, may be removed by surgery or treated by ablation. With many adenomas, removing all of them is often not possible, and the team weighs the risks of each option carefully.
Is a liver transplant ever needed?
Occasionally, for people with many adenomas that cannot be controlled, a suspected cancer, or a failing liver. Transplant also corrects the sugar problem in the liver types. It is assessed at licensed transplant centres, and the rules on donation and waiting lists change, so they must be checked there.
Can pregnancy affect liver adenomas?
Adenomas can grow under the influence of hormones, including in pregnancy. Women with this condition who are planning a pregnancy should talk first with their metabolic specialist and an obstetrician, so scans and blood sugar care can be planned ahead.
Is the contraceptive pill safe with adenomas?
Oestrogen-containing pills can make adenomas grow, so doctors usually advise other methods. Do not stop or start any contraception without advice. The page on adenoma and the pill explains the concern in more detail.
If cancer is found, how is it treated?
Much as for any HCC, planned on the size and number of tumours, how well the liver works and how fit you are. Options can include surgery, ablation, transplant or medicines. Your metabolic condition is managed alongside, because fasting before procedures needs special planning.
Where do I start if a lump has changed on my scan?
Gather your recent and older scan reports, and the images on disc if you have them, and your metabolic notes. Call the CION helpline, and someone will arrange for the tumour board to look at the scans and tell you plainly what should happen next.
