Surveillance for RAD51C carriers: what is checked and when | CION Cancer Clinics
If you carry a RAD51C fault, the usual plan is a yearly mammogram from around forty, with breast MRI considered. The ovaries cannot be screened reliably, so they are handled by a conversation about surgery later in the forties. Men follow routine screening. This page sets out the schedule across a lifetime, how family history changes it, and what checks can and cannot do. 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 checks does a RAD51C carrier actually need?
For women, the main checks are for the breasts, usually a yearly mammogram from around forty, with breast MRI considered alongside it. The ovaries cannot be screened reliably, so they are handled by a conversation about surgery later in the forties. Men who carry RAD51C follow the usual screening for their age.
Why the plan is lighter than for BRCA1
RAD51C raises breast cancer risk to a moderate degree, not to the high level seen with BRCA1 or BRCA2. Breast checks therefore start later and MRI is an option to discuss rather than a fixed part of the plan. The goal is the same: find a cancer while it is small.
Why your family can change the schedule
The average plan is a starting point. If your mother or sister had breast cancer young, checks usually begin earlier, often some years before the age at which she was diagnosed. A strong family history can also make MRI more clearly worthwhile. Your counsellor adjusts the plan to your family, not the other way round.
Treat this page as a map. Your written plan from your own team is the one to follow.Organ by organ
Which parts of the body are checked, and how?
The checks follow the risk. For RAD51C, that means the breasts and the ovaries, and very little else.
Breasts
A yearly mammogram is the core test, usually from around forty. Breast MRI may be added, especially if the family history is strong or the breast tissue is dense.
What you do yourself
- Know how your breasts normally look and feel
- Report a lump or change without waiting for the next check
Ovaries and tubes
No scan or blood test finds ovarian cancer early enough to rely on. Ultrasound and the CA-125 blood test are sometimes offered for reassurance, but they are not a safety net.
This is why surgery is discussed instead of a schedule.Men who carry it
No extra checks are recommended for men on the basis of RAD51C alone. Follow the usual screening for your age, and report any lump in the chest or change in passing urine.
Why his result still matters
- Each daughter has a one in two chance of inheriting it
- His sisters may carry it and need breast checks
Everything else
There is no routine bowel, pancreas, skin or prostate schedule for RAD51C carriers. If other cancers run in the family, those relatives' histories may add checks of their own. Tell your counsellor about every cancer on both sides of the family, not only breast and ovarian cancer, so nothing is left out of the plan.

Ask an oncologistAcross a lifetime
How does the schedule change as a carrier gets older?
-
Twenties and thirties
Usually no scans yet, unless a relative had breast cancer young. This is the time to get to know your own breasts and to have counselling in your own words, not through a parent.
-
Around forty
A yearly mammogram begins for women. Your team will say whether a yearly breast MRI should be added, and whether the two should be spaced across the year.
-
Mid to late forties
The conversation about removing the ovaries and tubes becomes active. Some women book surgery. Others agree a date to review the question.
-
After surgery or the menopause
Breast checks continue exactly as before. Surgery lowers ovarian risk, but it does not remove the need for breast checks.
-
Later life
The breast plan is reviewed as breast tissue changes. It is adjusted, not simply stopped, and your general health is taken into account.
On your plan
The words on your surveillance letter, in plain language
- Surveillance
- Regular checks designed to find a cancer early. It watches for cancer. It does not lower the chance of getting one.
- Mammogram
- A low-dose X-ray of the breast. It is the backbone of breast checks for RAD51C carriers.
- Tomosynthesis
- A mammogram taken as many thin slices, sometimes called a 3D mammogram. It can see through dense tissue a little better.
- Breast MRI
- A scan using a magnet and a dye injection, with no radiation. It is more sensitive than a mammogram but gives more false alarms.
- Recall
- Being asked back for another look after a scan. Most recalls turn out to be nothing.
- Interval cancer
- A cancer found between two planned checks, usually because you noticed a change. It is why breast awareness still matters.

Being straight with you
What this page cannot tell you
It cannot give you your own schedule. The start age, the choice of mammogram or MRI, and the timing of any surgery all depend on your age, your family history and your breast tissue. A genetic counsellor and a breast specialist will set that out with you. What your specific variant means is a question for the counsellor who ordered the test.
It cannot tell you where to be scanned
Breast MRI is available in Hyderabad but not in every district town. If you live outside the city, ask your team to plan checks so that a single trip covers as much as possible, and to write the plan down so a local doctor can follow it.
Who this does not apply to
This schedule is for people with a pathogenic or likely pathogenic RAD51C fault in their blood. A variant of uncertain significance does not qualify. Nor does a RAD51C change found only in a tumour, which is covered under targeted therapy.
Commonly believed
Four things carriers tell us about their checks, and what is true
"A yearly ovarian scan will keep me safe."
It will not. Scans and the CA-125 test miss many early ovarian cancers and raise false alarms. They are not a substitute for the surgery conversation.
"I need the same checks as my BRCA1 cousin."
RAD51C carries a lower breast risk, so checks usually start later and MRI is optional. Copying a BRCA1 plan adds cost and false alarms without clear benefit.
"My last scan was clear, so I can ignore this lump."
A cancer can appear between checks. Any new lump or change should be shown to a doctor straight away, whatever the date of your last scan.
"Once my ovaries are out, the checks stop."
Surgery deals with ovarian risk only. Breast risk is unchanged, so breast checks continue on the same schedule.
Questions we are asked
Common questions about RAD51C surveillance
When should breast checks start for a RAD51C carrier?
Guidelines generally suggest around forty. If a close relative had breast cancer at a younger age, checks often start earlier than her age at diagnosis. Your counsellor will give you a start date based on your own family.
Do I need breast MRI or is a mammogram enough?
For many RAD51C carriers, a yearly mammogram is the core test and MRI is considered case by case. A strong family history or dense breast tissue makes MRI more useful. It is a question to settle with your breast specialist.
Should I have a CA-125 test every year?
It is not recommended as screening, because it misses many early cancers and rises with harmless conditions too. Some doctors use it alongside ultrasound for women who are delaying surgery, but only as a stopgap.
What symptoms should I report between checks?
A new breast lump, skin dimpling or a nipple change. For the ovaries, bloating most days, feeling full quickly, lower tummy pain or passing urine more often, if they last more than a few weeks. Report them, do not wait.
Can I have my checks in my own district?
Mammograms are available in many district hospitals. Breast MRI is more limited outside Hyderabad. A written plan lets a local doctor follow the schedule, with a city visit only for the tests that need one.
Are the checks covered by insurance or schemes?
Cover for screening in people without cancer varies. Ask your insurer in writing, and check whether Aarogyasri or Ayushman Bharat applies. Our team can help you understand what is likely to be covered.
I am pregnant or breastfeeding. What happens to my checks?
Mammograms and MRI are usually paused or adapted during pregnancy and breastfeeding. Breast awareness matters more during this time, because changes can be harder to judge. Tell your team so the plan can be adjusted.
Who keeps track of my schedule?
Ideally, one named team, with the plan written down and a copy kept by you. Many carriers set reminders on their phone. The CION helpline can help you book checks and keep them on time.
