Tested positive for RAD51C: what happens next | CION Cancer Clinics
A positive RAD51C result means a fault has been found in a gene that helps repair broken DNA. It mainly raises the risk of ovarian cancer, and to a lesser degree breast cancer. Nothing needs to happen today. This page walks through what usually follows: the counselling appointment, a plan for breast checks, a later conversation about the ovaries, and testing 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 RAD51C result?
You see a genetic counsellor to go through the result. Women then get a plan for breast checks, and a conversation, usually later in adult life, about removing the ovaries and fallopian tubes. Relatives are offered a test for the same change. For men, the result matters mainly for their children and the wider family.
What the result means
RAD51C is one of the helpers in the same DNA repair system as BRCA1 and BRCA2. With one faulty copy, repair is less reliable, and over many years a cell in the ovary or the breast is more likely to go wrong. The ovarian risk is the one that is best established, and the one that shapes most decisions.
What it does not mean
It does not mean you have cancer, or that cancer is certain. RAD51C is a moderate risk gene, not as strong as BRCA1. Most carriers never develop ovarian cancer. The result is a reason to plan carefully, not a reason to act in a hurry, and most of the decisions ahead can be taken over months or years.
The ovary drives most decisions, because there is still no reliable screening test for ovarian cancer.The plan
What does care usually involve for a RAD51C carrier?
Care follows where the risk sits. For RAD51C, that is mainly the ovary, then the breast.
The ovaries
No screening test reliably finds ovarian cancer early. Instead, women discuss removing the ovaries and fallopian tubes once their family is complete, usually from the mid to late forties.
Worth knowing
- Removing the ovaries brings on menopause
- Hormone replacement is often possible afterwards
- Earlier discussion if a relative was diagnosed young
The breast
Breast checks are planned from your family history as well as the gene result. Many carriers are offered yearly mammograms, often starting earlier than usual, and some are offered breast MRI as well.
If you already have cancer
For ovarian or breast cancer, a RAD51C fault can open up tablets that target weak DNA repair, called PARP inhibitors. Your oncologist will say whether they suit your cancer, and when they would be used.
Men who carry it
A man has no clearly raised cancer risk of his own from a RAD51C fault. He can still pass it on, so he belongs in family testing.
His daughters and sons each have a one in two chance of inheriting it.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, confirms the variant is classed as pathogenic, and gives you a written summary. Bring a relative if it helps.
Mapping your own risk
Your age, your family history and any past cancer all change the picture. The counsellor adjusts the average figures to fit you.
A breast plan
A breast specialist sets out which scans you need and when. Ask for it in writing, so any doctor can follow it later.
A conversation about the ovaries
Not urgent for most younger women. A gynaecologist explains the timing, what the surgery involves and what menopause afterwards means.
Telling relatives
Parents, brothers, sisters and adult children are each offered a test for your exact change. A family letter from the counsellor can help.
On your report and in clinic
What do the words around a RAD51C result mean?
- Moderate risk gene
- A gene whose faults raise risk clearly, but less than the strongest genes such as BRCA1 and BRCA2.
- Risk-reducing surgery
- Removing healthy organs to lower the chance of cancer. For RAD51C this usually means the ovaries and fallopian tubes.
- Salpingo-oophorectomy
- The medical name for removing both the fallopian tubes and the ovaries.
- Triple-negative
- A type of breast cancer that lacks three common markers. It is seen more often in RAD51C carriers.
- PARP inhibitor
- A tablet treatment for some cancers with weak DNA repair. Used only once cancer is present, never as prevention.
- Cascade testing
- Testing relatives one branch at a time for the fault already found in the family.

Side by side
What changes after a positive result, and what does not?
What changes
What does not
Ovarian surgery is discussed in later adult life
Surgery is not usually advised in your twenties or thirties for this gene alone
Breast checks may start earlier
Your daily life, food and work
Relatives can be offered a simple test
Relatives who test negative return to routine screening
Some cancer treatments may become available
A cancer is still treated on its own features
Family planning can be discussed
Fertility itself is not affected by the gene
Being straight with you
What this page cannot tell you
It cannot tell you your own risk. The figures for RAD51C come from studies that are larger than they once were, but still smaller than those for BRCA1 and BRCA2. Your family history can push your risk above or below the average. What your specific variant means is a question for the counsellor who ordered the test.
It cannot tell you when to have surgery
The timing depends on your age, whether your family is complete, how young your relatives were when diagnosed, and how you feel about an early menopause. That decision is made with a gynaecologist and a counsellor over time, not from a web page.
Who this does not apply to
This page is for people with a confirmed pathogenic or likely pathogenic RAD51C result. A variant of uncertain significance should not lead to surgery or extra scans. A RAD51C change found only in a tumour is a different question about treatment, covered under targeted therapy.
Commonly believed
Four things families say after a RAD51C result, and what is true
"RAD51C is the same as BRCA, so I need the same surgery at the same age."
The ovarian risk is lower and tends to come later than with BRCA1. Surgery is usually discussed later too, and preventive breast surgery is not routinely advised for RAD51C alone.
"A yearly CA-125 blood test and ultrasound will protect me."
Neither test reliably finds ovarian cancer early enough to rely on. They are not a substitute for the surgery conversation.
"My father carries it, so he needs extra checks."
A man has no clearly raised risk of his own from RAD51C. His result matters for his children, who each have a one in two chance of inheriting it.
"My sister tested negative, so I must be negative too."
Each person inherits their genes separately. A sister's result tells you nothing certain about yours. Only your own test can answer that.
Questions we are asked
Common questions after a positive RAD51C result
Do I need surgery right away?
No. For most women, removing the ovaries and tubes is discussed from the mid to late forties, or earlier if a close relative had ovarian cancer young. There is time to think, finish your family and get a second opinion. Nothing about the result is an emergency.
Will removing my ovaries bring on menopause?
Yes, if you have not reached it yet. Hot flushes, sleep changes and thinning bones can follow. Hormone replacement is often possible for women who have not had breast cancer, and it can protect bones and heart. Your gynaecologist will talk through the options before any decision.
Do I need a mastectomy?
Preventive breast removal is not routinely advised for RAD51C alone. Some women with a strong family history of breast cancer do discuss it. For most, regular breast checks are the plan. It is a choice made with your breast surgeon and counsellor, not a default.
I already have ovarian cancer. Does this change treatment?
It can. A RAD51C fault means the cancer may respond to PARP inhibitors, tablets that target cells with weak DNA repair. Your oncologist will explain whether they suit your cancer, and at what stage of treatment they would be used.
Should my children be tested now?
Usually not until they are adults. RAD51C risks begin in adult life, so testing can wait until your children can decide for themselves. Make sure they know the result exists, so they can choose to test before planning a family.
What if my partner also carries a RAD51C fault?
If both parents carry a fault in this same gene, a child could inherit two faulty copies, which causes a rare and serious childhood condition. This is uncommon. If your partner's family has a similar history, or you are related by marriage within the family, tell your counsellor before pregnancy.
Will Aarogyasri or insurance cover this?
Surgery for a cancer may be covered. Preventive surgery and planned checks in a well woman often are not. Ask the scheme desk or insurer in writing before planning. India has no specific law against genetic discrimination in insurance, so discuss disclosure with your counsellor.
How do I arrange the next steps?
Call the CION helpline. Someone will help you book the results appointment, a breast review and a gynaecology consultation, and family counselling in Telugu if you prefer. You can ask questions before anything is booked.
