Screenings for people with Li-Fraumeni syndrome
Li-Fraumeni syndrome is a rare inherited disorder that greatly raises the risk of several types of cancer, particularly in children and young adults. The cancers most often linked to it are breast cancer, a bone cancer called osteosarcoma and soft tissue sarcomas; brain tumours, leukaemias and adrenocortical carcinoma are also common. It is thought to affect 1 in 5,000 to 1 in 20,000 people and is linked to changes in the TP53 gene. (MedlinePlus Genetics) European guidelines use the wider name heritable TP53-related cancer syndrome. (ERN GENTURIS, 2020) This page covers screening checks for adults only, not surgery, medicines or treatment.
The main guidance
The European Reference Network on genetic tumour risk syndromes (ERN GENTURIS) published guidelines in 2020, written by geneticists and clinicians in children's medicine, cancer care and radiology together with affected people and parent representatives. It says the guidelines support clinical decisions and do not replace clinical professionals. (ERN GENTURIS, 2020) UK consensus guidelines from the UK Cancer Genetics Group, also from 2020, adopted most of the international recommendations based on the Toronto protocol, with changes in a few areas. (UKCGG, 2020) An American Association for Cancer Research (AACR) working group updated its 2017 recommendations in 2025. Its summary says the Toronto protocol remains the current standard for lifelong surveillance, that the use of some tests should be adjusted by age, and that it now gives a more detailed outline for adults.

Whole-body and brain MRI
ERN GENTURIS says whole-body MRI allows early detection of tumours in people with a TP53 gene change and recommends a yearly whole-body MRI without gadolinium contrast dye in adults, plus a yearly brain MRI until age 50, with at least the first brain scan using contrast dye. (ERN GENTURIS, 2020) The UK guidelines include both scans because a pooled analysis found that whole-body MRI missed 5 of 10 brain tumours that a dedicated brain MRI found. They note that the arms are often not fully covered on most scanners and should be checked by examination, and that people are recalled for detailed imaging when a finding is unclear. (UKCGG, 2020) What whole-body MRI finds in this group, including how often it raises false alarms, is covered on full-body MRI screening, which also explains why self-pay scans for people without a condition like this are a different thing.
Breast MRI
ERN GENTURIS recommends a yearly breast MRI for women from 20 until 65. (ERN GENTURIS, 2020) The NHS Breast Screening Programme offers women with a TP53 gene change a yearly MRI from 20 to under 71 and says mammography is contraindicated for them. Women whose first-degree relative has a TP53 gene change but who have not been tested themselves are offered a yearly MRI from 20 to under 51. (NHS breast screening, 2025) The UK guidelines say clinical breast examination is not used as a screening test in the UK and that women should be taught breast self-examination instead. (UKCGG, 2020) See BRCA genetic test results for the other main breast cancer genes and dense breasts.
Skin, bowel and other checks
The UK guidelines advise a yearly skin review from age 18, which a GP can do with a low threshold for referral to a dermatologist. They do not advise routine blood counts, upper endoscopy or abdominal ultrasound in adults, and say colonoscopy is only needed with a family history of bowel cancer or polyps. They advise a detailed talk about warning symptoms and fast referral for symptoms that persist or are unusual. (UKCGG, 2020) ERN GENTURIS advises a colonoscopy every 5 years from 18 only after abdominal radiotherapy for an earlier cancer or with a family history of bowel tumours suggesting a higher genetic risk. (ERN GENTURIS, 2020) See skin cancer check: what to expect and screening colonoscopy: what to expect.
Children
Children have a separate schedule. ERN GENTURIS recommends a clinical examination and an abdominal ultrasound at least every 6 months, and yearly whole-body and brain MRI from birth when the gene change carries a high cancer risk in childhood. (ERN GENTURIS, 2020) A 2026 review says the 2025 AACR recommendations use shorter intervals in childhood: a physical examination and an abdominal and pelvic ultrasound every 3 to 4 months. (Cureus review, 2026) The care team for the child sets the plan.
Checks for relatives
MedlinePlus Genetics says Li-Fraumeni syndrome is inherited in an autosomal dominant pattern, meaning one changed copy of the gene is enough to raise cancer risk; in 7 to 20 percent of cases the gene change is new rather than inherited. (MedlinePlus Genetics) ERN GENTURIS says adult first-degree relatives should be offered testing for the same gene change. It says testing children from birth should be offered when the gene change is known to carry a high cancer risk in childhood, and otherwise discussed with parents, covering the burden and uncertain benefits of surveillance in childhood. (ERN GENTURIS, 2020) See family history and screening and how to collect your family health history.
Routine age-based screening
The USPSTF recommends a mammogram every 2 years for women aged 40 to 74, but says this does not apply to people with a genetic marker or syndrome linked to a high risk of breast cancer. (USPSTF breast, 2024) The other routine screenings for your age and sex still apply; see screenings by age and gender.
Where they differ:
- Brain MRI end age. ERN GENTURIS says yearly until 50, (ERN GENTURIS, 2020) while the UK guidelines give no end age. (UKCGG, 2020)
- Breast MRI end age. ERN GENTURIS says until 65, (ERN GENTURIS, 2020) the UK guidelines say until 70, (UKCGG, 2020) and the NHS programme invites women to under 71. (NHS breast screening, 2025)
- Yearly examination. ERN GENTURIS recommends a yearly clinical examination for adults, (ERN GENTURIS, 2020) while the UK guidelines do not recommend routine examination in adults and favour a talk about warning symptoms. (UKCGG, 2020)
- Colonoscopy. ERN GENTURIS includes abdominal radiotherapy for an earlier cancer as a reason, (ERN GENTURIS, 2020) while the UK guidelines name only a family history of bowel cancer or polyps. (UKCGG, 2020)
- Childhood intervals. ERN GENTURIS says every 6 months, (ERN GENTURIS, 2020) while the 2025 AACR recommendations, as a 2026 review reports, say every 3 to 4 months. (Cureus review, 2026)

Questions people ask
What checks do adults with Li-Fraumeni syndrome have?
The 2020 European guideline (ERN GENTURIS) recommends that adults with a disease-causing TP53 gene change have a yearly clinical examination, a yearly whole-body MRI without contrast dye, a yearly brain MRI until age 50, and, for women, a yearly breast MRI from age 20 until 65. A colonoscopy every 5 years from age 18 is advised only after abdominal radiotherapy for an earlier cancer or with a family history of bowel tumours. (ERN GENTURIS, 2020)
Why is a brain MRI done as well as a whole-body MRI?
UK consensus guidelines say a pooled analysis that compared the two found that whole-body MRI missed 5 of 10 brain tumours that a dedicated brain MRI found, so both scans were included. They say contrast dye is needed for the first brain scan but not later ones. (UKCGG, 2020)
Do women with Li-Fraumeni syndrome have mammograms?
Not in the NHS programme. The NHS Breast Screening Programme offers women with a TP53 gene change a yearly breast MRI from 20 to under 71 and says mammography is contraindicated for this group. The European guideline recommends yearly breast MRI from 20 until 65. (NHS breast screening, 2025) (ERN GENTURIS, 2020)
Is the USPSTF breast screening advice for people with Li-Fraumeni syndrome?
No. The USPSTF says its breast cancer screening recommendations do not apply to people who have a genetic marker or syndrome associated with a high risk of breast cancer. (USPSTF breast, 2024)
Should relatives be tested?
The European guideline says adult first-degree relatives of someone with a disease-causing TP53 gene change should be offered testing for the same gene change. Testing in childhood is offered when the gene change is known to carry a high cancer risk in childhood, and otherwise discussed with parents, including the burden and uncertain benefits of surveillance in childhood. (ERN GENTURIS, 2020)
