POLE or POLD1 positive: what happens next | CION Cancer Clinics
A POLE or POLD1 result means a fault in one of the genes that proofread DNA as cells copy it. It raises the chance of bowel polyps and bowel cancer, and for some carriers womb and other cancers. The next steps are usually a counselling visit, a colonoscopy, a plan for regular checks and testing for close relatives. This page walks through those first months in order. At CION Cancer Clinics, our oncologists explain what a gene result means for you and your family, and plan the checks that follow.

The short answer
I have just been told I carry a POLE or POLD1 fault. What now?
Nothing needs to happen tonight. A POLE or POLD1 fault raises your chance of bowel polyps and bowel cancer, but it does not mean you have cancer. The next steps are a meeting with a genetic counsellor, a first colonoscopy if you have not had one recently, and a written plan for regular checks.
First, check what the result actually says
Many changes in these two genes are harmless. Only faults in the proofreading part of each gene are known to raise cancer risk. Your report should say pathogenic or likely pathogenic, which means the laboratory is confident the change breaks the gene. If it says uncertain significance, the plan is very different and this page does not apply yet.
Why this result is less familiar than most
POLE and POLD1 faults are rare. Far fewer families have been described than for Lynch syndrome or the APC gene, so doctors have less long-term experience to draw on. Guidance is still being written, and your plan may be adjusted as more is learned. That is normal, not a sign that something was missed.
A carrier is not a patient. Most of what follows is about watching, not treating.The people involved
Who will I see after a positive result?
Several specialists share the work. You do not need to find each of them yourself.
Genetic counsellor
Goes through the report line by line, draws your family tree and explains what the fault means for you and your relatives. This is where you ask the questions you were too shocked to ask on the day.
Bring with you
- The original report, not a photo of it
- Relatives with cancer, and their ages at diagnosis
- Any past colonoscopy reports
Gastroenterologist
Does the colonoscopy and, for POLE carriers, may also look at the stomach and the first part of the small bowel. Small polyps found this way are usually removed during the same test.
Gynaecologist, for women
Faults in POLD1 in particular have been linked to cancer of the womb. Women are usually offered a talk about symptoms to report, and sometimes about options once their family is complete.
Report bleeding between periods or after the menopause.Oncologist, if you have cancer
If the result was found because of a cancer, your oncologist uses it alongside tests on the tumour itself. These tumours often carry very many gene changes, which can matter when treatment is chosen.
Not sure whether this applies to you?
Ask an oncologistThe first few months
What happens, and in what order?
The counselling visit
Usually soon after the result. The counsellor confirms the variant, explains the risks linked to your gene, and discusses which relatives should be offered a test.
A baseline colonoscopy
If you have not had one recently, this comes first. It shows whether polyps are already present and sets how often you will be checked after that.
An upper endoscopy, if advised
POLE carriers in particular may be offered a camera test of the stomach and duodenum, the first part of the small bowel, because polyps can grow there too.
A written surveillance plan
You should leave with a plan on paper: which tests, how often, and who books them. Keep it with your report so any doctor you see can read it.
Letters to relatives
Your counsellor can give you a family letter explaining the result, so brothers, sisters and grown-up children can take it to their own doctor.
On your report
What do the words on a POLE or POLD1 report mean?
- Polymerase
- The machinery that copies DNA each time a cell divides. POLE and POLD1 hold the instructions for two of the main copiers.
- Proofreading
- The copier's built-in check. It spots a wrong letter as it goes in and removes it. The faults that matter switch this check off.
- Pathogenic variant
- A spelling change known to break the gene. Likely pathogenic means the laboratory is nearly as sure. Both are acted on in the same way.
- Variant of uncertain significance
- A change nobody can yet call harmful or harmless. It should not be used to plan surgery or to test relatives.
- Polyposis
- Having many polyps in the bowel rather than one or two. In POLE and POLD1 carriers this is called polymerase proofreading-associated polyposis, or PPAP.
- Germline
- Present in every cell from birth, so it can pass to children. A fault found only inside a tumour is called somatic.

Being straight with you
What this page cannot tell you
It cannot tell you what your specific variant means. That is a question for the counsellor who ordered the test. Two people with faults in the same gene can have different risks depending on exactly where the change sits, and the evidence for some variants is still thin.
It cannot give you your personal risk
Studies of POLE and POLD1 families so far are small, and almost none come from India. Risk estimates published abroad may shift as more families are found. Anyone who gives you a precise figure for your own lifetime risk is claiming more certainty than the evidence allows.
Who this does not apply to
If your POLE change was found only in a tumour, not in a blood or saliva test, it is a different finding. Tumour-only POLE changes are common in some womb and bowel cancers and are not inherited. That result belongs with your oncologist and our targeted therapy team. If a relative carries the fault and you tested negative for it, this plan is not for you either.
Unsure whether your result came from blood or from the tumour? The report heading usually says germline or somatic.Commonly believed
Four things families tell us, and what is actually true
"A positive result means I will get bowel cancer."
It raises risk. It does not settle it. Regular colonoscopy removes polyps before they have the chance to turn into cancer, which is the whole point of the plan.
"This is the same as Lynch syndrome."
Both involve errors made when DNA is copied, but they are different genes with different patterns. Tumour tests that flag Lynch syndrome usually look normal in POLE and POLD1 carriers, which is one reason these faults are easy to miss.
"If I feel well, I can skip the colonoscopy."
Polyps rarely cause symptoms while they are small. By the time something is felt, the chance to remove a polyp early has often passed. Feeling well is exactly when the checks work best.
"My brother tested negative, so I do not need to."
Each child of a carrier has their own separate one in two chance. A brother's negative result tells you nothing about yours. You need your own test.
Questions we are asked
Common questions after a POLE or POLD1 result
How soon should I have my first colonoscopy?
Your team will set the timing, based on your age and any past checks. Most carriers who have not been examined recently are offered one soon after the result. If you have bleeding from the bottom, a change in bowel habit or unexplained weight loss, say so, because that brings it forward.
Will I need surgery to remove my bowel?
Most carriers do not. Polyps are usually removed during colonoscopy. Surgery is considered only if there are too many polyps to manage this way, or if a cancer is found. Your team will discuss it as one option among several, never as an automatic step.
Should my children be tested now?
Usually not in early childhood. Testing is normally offered around the age when bowel checks would begin, so the young person can take part in the decision. Your counsellor will tell you when that point comes for your family, and how to explain it to them.
Is immunotherapy relevant to me?
Only if you have cancer. Tumours in POLE and POLD1 carriers often carry many gene changes, and tumours like this sometimes respond to immunotherapy. Whether that applies to your cancer is decided by your oncologist using tests on the tumour. For a well carrier, it plays no part in the plan.
Does this affect my womb or other organs?
POLD1 faults in particular have been linked to cancer of the womb, and small numbers of brain, ovarian and other cancers have been reported in POLE families. Evidence outside the bowel is thin. Your counsellor will say which organs, if any, need extra attention in your case.
Can I still have children?
Yes. The fault does not affect fertility. Each child has a one in two chance of inheriting it. Some couples want to discuss testing before or during a pregnancy, and a counsellor can explain what is available and legal in India.
Will this affect insurance or marriage?
India has no law that specifically protects genetic results in insurance, so talk to your counsellor before sharing the result widely. Families also worry about marriage. Who you tell, and when, is your decision, and counsellors are used to helping families think it through.
Where do I start if I live outside Hyderabad?
Keep your report and any past colonoscopy results together. Call the CION helpline and describe your result. We can arrange a counselling appointment and tell you which checks can be done nearer home and which are better done in Hyderabad.
