Tested positive for PTEN: what happens next | CION Cancer Clinics
A positive PTEN result means a fault has been found in a gene that normally keeps cell growth in check. It raises the chance of several cancers, but it does not mean cancer is certain, and nothing needs to happen today. This page walks through what usually follows: the counselling appointment, the first round of checks, a lifelong plan, and telling the family. 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
What happens after a positive PTEN result?
First, a follow-up appointment with a genetic counsellor to explain the result. Then a baseline examination, and a schedule of regular checks for the thyroid, skin, breast, womb, kidney and bowel. Then a conversation about which relatives should be offered a test. None of this is urgent in the way a cancer diagnosis is. It is planning.
What a positive result actually means
You carry a PTEN fault in every cell of your body, from birth. The condition it causes is called PTEN hamartoma tumour syndrome, and Cowden syndrome is one form of it. It raises the lifetime chance of breast, thyroid, womb, kidney and bowel cancer, and of melanoma, above that of the general population.
What it does not mean
It does not mean you have cancer. It does not mean you will develop cancer. It does not mean your children have inherited it either. Each child has a one in two chance, and a simple test can tell each one for certain. Many carriers live long lives with their checks running quietly in the background.
A positive result is the start of a plan, not a diagnosis.Your care team
Who will be involved in your care from now on?
PTEN affects several organs, so no single doctor covers everything. Someone should hold the whole plan together.
Genetic counsellor
Explains the result, draws the family tree and helps you decide who to tell and how. Also the person to call if the laboratory later updates how your variant is classified.
A coordinating doctor
Usually your oncologist. Holds the overall surveillance plan and makes sure no check is missed. If you already have cancer, they explain whether the result changes your treatment.
Organ specialists
Each organ has its own check, so each has its own specialist.
Usually includes
- An endocrinologist for the thyroid
- A breast specialist and gynaecologist for women
- A gastroenterologist for colonoscopy
- A dermatologist for the yearly skin check
For children
A paediatrician watches growth and development, and arranges thyroid checks from childhood. Some children also benefit from a developmental assessment and extra support at school.
PTEN is one of the few conditions where testing children is usually recommended.Not sure whether this applies to you?
Ask an oncologistThe first few months
What are the next steps, in order?
The results appointment
The counsellor explains the result and gives you a written summary. Bring a relative if you want someone else to remember the details.
A baseline check
A full examination, a thyroid ultrasound, a skin check and, for women, a breast and gynaecology review. These set the starting point for every later comparison.
A written surveillance plan
A list of which check happens when, for life. Ask for it on paper so any doctor you see later can follow it.
Telling relatives
Parents, brothers, sisters and children are each offered a test for your exact change. The counsellor can write a family letter to help you explain.
Thinking about preventive options
Some women later discuss preventive breast or womb surgery. It is one choice among several, never rushed, and covered on its own pages.
On your report
What do the words on a positive PTEN report mean?
- Pathogenic variant
- A change known to break the gene. A likely pathogenic result is treated the same way when planning care.
- Heterozygous
- One faulty copy and one working copy. This is what almost every PTEN carrier has.
- Autosomal dominant
- The inheritance pattern. One faulty copy is enough to raise risk, and each child of a carrier has a one in two chance of inheriting it.
- De novo
- A fault that appeared for the first time in you, with neither parent carrying it. This happens fairly often with PTEN.
- Surveillance
- Planned, regular checks in a person who feels well, aimed at finding a problem early.
- Cascade testing
- Testing relatives one branch at a time for the fault already found in the family.

A cancer is still treated on its own features
Being straight with you
What this page cannot tell you
It cannot tell you what your own variant means. PTEN results vary, and a few variants behave differently from the usual pattern. What your specific variant means is a question for the counsellor who ordered the test, not for a search engine.
It cannot give you your own level of risk
Published risk figures for PTEN come from studies that are still fairly small. Many of the families studied were found because they had a lot of cancer, so the headline figures may overstate the risk for a family found some other way. A counsellor can explain what the evidence does and does not show for you.
Who this does not apply to
This page is for people with a confirmed pathogenic or likely pathogenic PTEN result. If your report says variant of uncertain significance, none of these steps apply yet. If tumour testing found a PTEN change in the cancer only, that is a question about treatment, covered under targeted therapy.
Commonly believed
Four things families say after a PTEN result, and what is true
"I need surgery straight away."
Nothing about a PTEN result is an emergency. Preventive surgery is a choice some carriers consider later, after time to think, and many never choose it.
"My brother looks well, so he does not need a test."
PTEN signs vary a great deal, even within one family. A brother with no obvious features can still carry the fault and pass it to his children.
"My parents do not have it, so the result must be wrong."
Some PTEN faults appear for the first time in one person. Parents testing negative is not a sign of a laboratory error, and your own children still have a one in two chance.
"There is a medicine that removes the fault."
A gene fault cannot be corrected or reversed. Medicines that act on the PTEN pathway are being studied, but for now care means watching closely and acting early.
Questions we are asked
Common questions after a positive PTEN result
How soon should the first checks happen?
Within the next few months is usual, not the next few days. If you already have symptoms, such as a neck lump or unusual bleeding, tell your doctor now rather than waiting for the planned schedule. Otherwise the baseline checks can be booked calmly, and grouped into as few visits as possible.
Should my children be tested now?
Usually yes, because PTEN is one of the conditions where checks start in childhood, especially for the thyroid. Your counsellor will talk you through timing and how to explain it to the child. A negative result lets a child skip checks they do not need.
Will this change my breast cancer treatment?
It can. If you have breast cancer now, a PTEN result may shape the choice of surgery, for example whether to remove one breast or both. Your surgeon and oncologist will discuss this with you. The decision is still yours, and there is usually time to make it.
Do I have to tell my employer or insurer?
No law in India requires you to tell your employer. India also has no dedicated law protecting against genetic discrimination in insurance, so raise any insurance questions with your counsellor before sharing the result widely.
Can I still have children?
Yes. A PTEN fault does not affect fertility. Each child has a one in two chance of inheriting it. Some couples choose testing during pregnancy, or IVF with embryo testing. Others simply test the child after birth. A counsellor can explain each route without pressure.
My result says likely pathogenic. Is that different?
For planning care it is treated the same as pathogenic. It means the laboratory is very confident, though not certain, that the change breaks the gene. Ask how you will be told if the classification ever changes.
Will I need checks for the rest of my life?
For most carriers, yes, though the mix of checks changes with age. Some start in childhood, others in the thirties or forties. Your team reviews the plan regularly and adjusts it as guidance changes.
Who can help us arrange the next steps?
Call the CION helpline. Someone will help you book the results appointment, the baseline checks and family counselling, and can arrange for the conversation to happen in Telugu. You do not need a referral letter to ask.
