Why HLRCC kidney surveillance starts in childhood | CION Cancer Clinics
Children who carry an FH fault are usually offered their first kidney MRI around the age of eight to ten. The kidney cancer linked to HLRCC can appear young and can spread while it is still small, so waiting for symptoms is not safe. A yearly scan finds a tumour early. Children who test negative for the family fault need no scans at all. At CION Cancer Clinics, our oncologists plan screening and care for families with an inherited cancer syndrome, explained in plain words.

The short answer
Why do children with HLRCC need kidney scans?
Because the kidney cancer linked to HLRCC has occasionally been found in teenagers, and it can spread while it is still small. Starting scans in childhood means that if a tumour ever forms, it is found early, usually long before it causes any symptoms. International guidance suggests the first kidney MRI at around the age of eight to ten.
Why this differs from other inherited kidney conditions
In several other inherited conditions, small kidney tumours grow slowly. Doctors can safely watch them for a while and scans start later in life. The FH-deficient kidney tumour does not behave like that. Size is a poor guide to how dangerous it is, so the plan relies on finding it as early as possible.
What this means for a family
Once a parent is known to carry an FH fault, the question is no longer only about adults. A counsellor will talk about testing the children too. Children who do not carry the fault need no scans at all. Those who do can be watched calmly, once a year, by people who know the condition.
Most children who carry an FH fault will never develop kidney cancer in childhood. The early start is a safety net.The reasoning
What makes doctors start HLRCC kidney checks so young?
Four features of this tumour together explain the early start and the yearly rhythm.
It can appear young
Most kidney cancer affects older adults. The HLRCC tumour has been reported in people in their twenties and, rarely, in their teens.
It can spread while small
A small tumour can already have reached the glands nearby. Waiting to see whether it grows is not the usual approach in HLRCC.
It is silent at first
Early kidney tumours rarely cause pain or blood in the urine. By the time symptoms appear, the tumour has often grown.
Symptoms usually come late
- Blood in the urine
- Pain in the side or back
- A lump in the tummy
MRI is safe to repeat
MRI uses a magnet, not radiation. It can be repeated every year for a lifetime without the radiation dose that repeated CT scans would add up to. That is why it is the preferred scan.
Ultrasound alone can miss small or cyst-like tumours.Not sure whether this applies to you?
Ask an oncologistAcross a lifetime
What does HLRCC kidney surveillance look like, from childhood on?
-
A parent's result is confirmed
An FH fault is found in a parent or another close relative. The counsellor explains that each child has a one in two chance of carrying it.
-
The child is offered a test
For most adult-onset conditions, children are not tested. HLRCC is an exception, because a result changes what is done in childhood. The test is a simple blood sample.
-
The first kidney MRI
Usually planned around the age of eight to ten. Many children manage the scan awake with a parent nearby. A few need mild sedation.
-
A yearly scan through the teens and adulthood
The same scan is repeated once a year, ideally at the same centre so the images can be compared. Skin and, for women, gynaecology checks are added in adult life.
-
Prompt action if anything is seen
A suspicious area is reviewed quickly by a specialist who knows HLRCC. It is not left for the next yearly scan.
On the scan report
What do the words on a kidney MRI report mean?
- Surveillance
- Regular checks in someone who is well, to find a problem early. It is not treatment.
- Contrast
- A liquid given into a vein during the scan so the kidneys show up more clearly.
- Lesion
- Any area that looks different from normal tissue. Many lesions are harmless, but in HLRCC each one is reviewed.
- Simple cyst
- A thin-walled pocket of fluid. Very common and almost always harmless.
- Complex cyst
- A cyst with thick walls or solid parts. In an FH carrier this needs a specialist's opinion.
- FH-deficient renal cell carcinoma
- The kidney cancer linked to HLRCC, in which the tumour has lost the FH enzyme.

Do not wait for the next yearly scan
If you or your child carry an FH fault and notice blood in the urine, a pain in the side or lower back that does not settle, or a lump in the tummy, contact your doctor the same day. Say that the family carries an FH fault and ask for the kidneys to be imaged quickly. Do not wait for the scheduled scan, and do not assume it is a urine infection.
Being straight with you
What this page cannot tell you
It cannot tell you when your own child should start scans, or what a finding on a scan means. Those decisions depend on the family result, the ages at which relatives were affected and the images themselves. What your specific variant means is a question for the counsellor who ordered the test.
Where the evidence is thin
The advice to start in childhood comes from expert consensus, built on the small number of very young cases reported worldwide. There are no large trials comparing different starting ages. Almost no Indian children with HLRCC have been described in the medical literature. We would rather say that plainly than sound more certain than the evidence allows.
Who this does not apply to
Children in families where no FH fault has been confirmed do not need kidney MRI because of this page. Nor do children who have tested negative for the family's known fault. Their kidney risk is the same as any other child's, and scanning them adds worry without benefit.
A negative test in a child from an HLRCC family ends the need for kidney scans for that child.Commonly believed
Four things parents believe about early kidney scans, and what is true
"Children do not get this kind of kidney cancer."
It is rare in children, and most carriers never develop it young. It has been reported in teenagers, though, which is exactly why scans begin before the teenage years.
"An ultrasound is just as good and costs less."
Ultrasound is useful for many things, but it can miss small or cyst-like HLRCC tumours. MRI is the recommended scan. If ultrasound is ever used, it should not replace MRI.
"We will scan once symptoms start."
By the time this tumour causes symptoms it has often grown or spread. The whole purpose of surveillance is to find it while it is silent and small.
"Testing a child for a gene fault is always wrong."
For conditions that only matter in adult life, testing is usually left until the child can decide. HLRCC is different, because a positive result starts scans in childhood that can protect the child.
Questions we are asked
Common questions about early HLRCC kidney checks
At what age should the first kidney scan happen?
International guidance suggests around the age of eight to ten for a child known to carry the family's FH fault. Your counsellor or oncologist may adjust this, for example if a relative was affected unusually young. The plan is always made for your family specifically.
How often is the scan repeated?
Once a year is the usual rhythm, for life. If a scan shows something that needs a closer look, the next one may come sooner. Using the same scanning centre each year makes it easier to compare images and spot small changes.
Will my child need to be sedated?
Many children of that age manage the scan awake, especially if they know what to expect and a parent can stay close. The machine is noisy and they need to lie still. A small number need mild sedation, which the scanning team will discuss beforehand.
Is the contrast injection safe for a child?
The contrast used for MRI is widely given to children and serious reactions are uncommon. The team checks kidney function and allergies before giving it. If you have concerns, ask the radiologist to explain the choice for your child.
My child tested negative. Do they still need scans?
No. A child who does not carry the family's known FH fault has the same kidney risk as any other child. No HLRCC surveillance is needed, and your child cannot pass the family fault to their own children.
What if the scan finds a cyst?
Simple cysts are common and usually harmless. In an FH carrier, a cyst with thick walls or solid parts is reviewed promptly by a specialist who knows HLRCC. Ask for the report to be seen quickly rather than at the next routine visit.
Are yearly scans covered by any scheme?
Coverage for surveillance in someone who is well varies between insurers and government schemes such as Aarogyasri and Ayushman Bharat. Ask the hospital's insurance desk before the first scan. Your counsellor can provide a letter explaining why the scan is needed.
Where do we start if a parent has just tested positive?
Ask the counsellor who gave the result about testing your children and arranging their first scan. Keep a copy of the report for every child's file. The CION helpline can point you to the right clinic if you are unsure where to go.
