Tested positive for MEN1: what happens next | CION Cancer Clinics
A positive MEN1 result is rarely urgent. It means you carry a fault that makes growths in hormone glands likely over your lifetime, not that you have cancer today. What follows is a set of baseline blood tests and scans, a written plan of regular checks and an offer of testing for close relatives. This page walks through the first year, step by step. 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 tested positive for MEN1. What happens now?
Usually nothing urgent. A positive MEN1 result means you carry a fault that makes growths in hormone glands likely over your lifetime. The next step is a set of baseline blood tests and scans, a lifelong plan of checks, and an offer of testing for your close relatives.
What the result does mean
It means the brake on growth in your parathyroid, pancreas and pituitary cells is weaker than normal. Growths are likely at some point, and some may already be there without symptoms. Finding them early, while they are small, is the whole purpose of what comes next.
What the result does not mean
It is not a cancer diagnosis. It does not mean you need an operation now, and it does not mean your life has to change shape. Many carriers work, marry, raise children and travel exactly as before, with a few appointments a year added to the calendar.
If you were tested because a relative has MEN1
You may have no symptoms at all, and that is the best position to be in. Your checks can start before any gland has caused trouble. Your relative's history also tells the team which glands to look at first, and which surgeons and centres the family has already found helpful.
If you already have symptoms, such as kidney stones or repeated ulcers, tell the team at your first visit. They may change the order of tests.Your care team
Who will be looking after you?
MEN1 touches several glands, so several specialists are involved. One of them should lead.
An endocrinologist
The hormone specialist who usually leads MEN1 care. They order the blood tests and scans, read the results over time and decide when a growth needs more than watching.
Ask them for
- A written plan of checks
- Copies of every report and scan
- Who to call if symptoms start
A genetic counsellor
Explains the result, answers questions about children and marriage, and writes a family letter so relatives can be tested for the same fault. They can do this in Telugu.
A surgeon
An endocrine or pancreas surgeon joins only if a growth needs removing. Experience with MEN1 matters, because the operations differ from those for a one-off growth.
Usually brought in for
- Overactive parathyroids
- A pancreas growth releasing insulin
- A silent growth that keeps enlarging
An oncologist
A cancer specialist becomes involved if a pancreas, thymus or lung growth behaves like cancer. For most carriers this never happens, but it helps to know who would step in.
Not sure whether this applies to you?
Ask an oncologistThe first year
What does the first year after a positive result look like?
-
The result is explained properly
A post-test counselling session goes through what the fault means, what it does not mean and who in the family is at risk. Bring a relative and write your questions down beforehand.
-
Baseline blood tests
Calcium, parathyroid hormone, prolactin, gastrin and fasting sugar are checked to see whether any gland is already overactive. Most are taken from one blood sample.
-
Baseline scans
An MRI of the pituitary and a scan of the pancreas and chest look for growths that blood tests cannot see. These first pictures become the comparison for every later scan.
-
A written surveillance plan
Your endocrinologist sets out which tests you will have and how often. Keep a copy, especially if you move or change doctors.
-
Your relatives are offered testing
Parents, brothers, sisters and children are offered a test for your exact fault. Those who test negative need no special checks at all.
Words you will hear
What do the terms in your follow-up letters mean?
- Baseline
- The first full set of tests after diagnosis. Every later result is compared with it to spot change.
- Surveillance
- Planned, regular checks in someone who is well, to find a growth before it causes symptoms.
- Cascade testing
- Testing relatives one branch at a time for the fault already found in the family.
- Functioning tumour
- A growth that releases a hormone and so causes symptoms, such as high calcium or low sugar.
- Non-functioning tumour
- A growth that releases no hormone. It is silent and only found on a scan.
- Tumour board
- A meeting where specialists review scans together and agree a plan, so the decision is not one doctor's alone.

Commonly believed
What do people fear most after a positive result?
"I will need surgery straight away."
Most people have no operation at diagnosis. Surgery is planned only when a growth is causing harm or keeps growing, and even then it is one option among several.
"It is safer to keep this from the family."
Silence leaves relatives unchecked, and a sister or son could carry the same fault without knowing. Your counsellor can help you decide how and when to tell each person, including in-laws.
"Regular checks mean I am ill."
Checks are for people who are well. Most visits end with normal results. When something is found, it is usually small and easier to manage than it would have been later.
"My children are too young to think about this."
MEN1 is one of the few conditions where testing in childhood is usually advised, because some growths can appear young. Your counsellor will suggest the right age.
Being straight with you
What can this page not tell you?
It cannot tell you what your own tests will show, or which gland will be affected first. It cannot set your schedule of checks, which depends on your age, your baseline results and your family history. What your specific variant means is a question for the counsellor who ordered the test.
It cannot replace your lead doctor
MEN1 care goes wrong most often when each gland is treated by a different doctor who never sees the others' notes. One endocrinologist who holds the whole picture is worth more than any page you read.
Who this does not apply to
This page is for people with a confirmed MEN1 fault. If your result says variant of uncertain significance, it is not a positive result, and nothing here applies until it is reclassified. If you were tested because of one parathyroid growth and the result was negative, you do not have MEN1.
Questions we are asked
Common questions after a positive MEN1 result
Is a positive MEN1 result an emergency?
No. The fault has been there since birth, and a few more days changes nothing. Book the baseline tests calmly. The only exception is a symptom that needs attention anyway, such as fainting from low sugar, which should be seen the same day.
How often will I have tests?
Blood tests are usually yearly, and scans less often, but the exact plan is set by your endocrinologist from your baseline results. The plan tightens if something is found and may relax if a gland has been treated.
Can I still get married and have children?
Yes. Each child has a one in two chance of inheriting the fault. Some couples choose testing during pregnancy or embryo testing with IVF, and many simply test the child early. A counsellor can explain each option without pressure.
Do I have to tell the family I am marrying into?
It is a personal decision, and worth thinking through before the wedding rather than after. Many families find honesty easier in the long run, because future children may need testing. A counsellor can help you plan that conversation.
Will I need to change my diet?
Not because of the result itself. If calcium is high, drinking plenty of water helps protect the kidneys. If a growth causes low sugar, regular meals and a sugary snack on hand help until it is treated. Your doctor will say if anything else applies.
Will Aarogyasri or Ayushman Bharat cover the costs?
They may cover some operations and treatment, depending on the scheme and hospital. Routine surveillance tests are often paid for directly. Ask the hospital's insurance desk before each step, and keep all reports and bills together.
What if I get new symptoms between checks?
Do not wait for the next appointment. Kidney stones, ulcers that keep returning, episodes of shaking and confusion when hungry, new headaches or changes in periods should all be reported to your team straight away.
Who should I call first?
The doctor or counsellor who gave you the result should arrange your first endocrinology visit. If that has not happened, call the CION helpline. We can help arrange counselling, the baseline tests and a lead doctor for your care.
