A family screening checklist after liver cancer | CION Cancer Clinics
Test close relatives for hepatitis B and C, vaccinate anyone unprotected, and arrange follow-up for anyone who carries a virus. That is the core of the checklist. Liver cancer clusters in families mostly because these viruses pass between relatives, not because the cancer is inherited. This page lists who to include, which blood tests to ask for, and what each result should lead to. At CION Cancer Clinics, our specialists help you understand your own risk and plan regular liver checks that fit it.

The short answer
What should a family check after a liver cancer diagnosis?
Start with one question: what caused the patient's liver disease? If it was hepatitis B or C, close relatives need a simple blood test, and anyone unprotected against hepatitis B needs the vaccine. Liver cancer clusters in families mostly because these viruses do, not because the cancer itself is inherited.
Why a checklist helps
After a diagnosis, the family is busy with appointments, money and worry. Testing the relatives gets pushed back, then forgotten. A short written list, kept with the patient's reports, makes sure every brother, sister, child and spouse is checked once and that each result leads to a clear next step.
Which liver cancer this is about
This checklist is for primary liver cancer, the kind that starts in the liver, often called HCC. If the cancer spread to the liver from another organ, ask the treating team about family risk for that first cancer. Our page on why liver cancer runs in families without being genetic explains the difference in more detail.
Nobody on this list is being blamed. Most hepatitis B carriers caught the virus as babies.Who goes on the list
Which family members should be checked?
If the patient has hepatitis B, these are the people to list by name. If the cause was hepatitis C, the list is usually shorter, because it spreads mainly through blood.
The patient's mother and siblings
Hepatitis B most often passes from mother to baby around birth, so brothers and sisters born to the same mother are among the most likely to share it.
- Mother, if living
- Every brother and sister
The spouse or partner
Hepatitis B can spread through sexual contact. A spouse who tests negative and has no protection should be vaccinated.
Children and grandchildren
Children of a mother who carries hepatitis B are at the highest risk. Children of a father who carries it should be tested too, because the virus can pass between people living in the same home.
Any pregnant woman in the family who carries the virus should tell her obstetrician early.Others in the same household
People who share razors or toothbrushes, or care for the patient's wounds, can be exposed to blood. Ask the doctor whether they should be tested or vaccinated as well.

How do we work through the checklist, step by step?
Write down the patient's cause
Ask the treating doctor whether the liver disease came from hepatitis B, hepatitis C, alcohol, fatty liver or another condition. Note it at the top of the list.
List every close relative by name
Use the groups above. Add each person's phone number, so one person in the family can follow up with all of them.
Book the blood tests
For hepatitis B, the usual tests are HBsAg and anti-HBs. For hepatitis C, anti-HCV. See our page on what family members should be tested for.
Act on each result
Tick each name only when a next step is done: vaccinated, booked with a doctor, or told no action is needed. A result in a drawer protects nobody.
Result and next step
What should each relative do with their result?
If the result shows
The usual next step
HBsAg positive
See a hepatologist or physician about antiviral tablets and regular liver scans
HBsAg negative, anti-HBs negative
Not infected and not protected: have the hepatitis B vaccine
HBsAg negative, anti-HBs positive
Protected: usually nothing more is needed for now
Anti-HCV positive
A second blood test checks whether the virus is active; if so, tablets can clear it
Only anti-HBc positive
Past contact with the virus: a doctor needs to interpret this one

Commonly believed
What stops families finishing the checklist?
"We will test the children once the patient's treatment is over."
Testing a relative takes a single blood sample and does not need to wait. Vaccinating an unprotected child now is far simpler than managing an infection later.
"If one sibling is negative, the others will be too."
Each person's result is their own. One brother can carry hepatitis B while another does not, even in the same house. Everyone on the list needs their own test.
"A carrier with normal liver tests does not need follow-up."
Liver tests can look normal while the virus is quietly active. A carrier needs a doctor to decide how often they should be checked, and some need scans even without cirrhosis.
"Our family cannot have it, because nobody drinks."
Hepatitis B has nothing to do with drinking. It is a virus, usually caught in childhood. Families who never touch alcohol can still carry it.
Did you know
India's National Viral Hepatitis Control Programme offers testing and treatment for hepatitis B and C through government health facilities. What is offered and where can change, so check with your nearest government hospital or ask the CION helpline to point you in the right direction.
Being straight with you
What this page cannot tell you
It cannot read a relative's report for you. Hepatitis B results come in combinations, and the same marker can mean different things alongside different results. A doctor should look at all of them together before anyone is told they are safe or need treatment.
Who this checklist does not apply to
If the patient's liver disease came only from alcohol or fatty liver, with no hepatitis B or C, relatives do not need virus testing because of the diagnosis. Their own drinking, weight and blood sugar are what matter. A rare inherited condition such as haemochromatosis needs its own testing, which a doctor will suggest if blood results point that way.
Who to ask
Antiviral decisions belong to a hepatologist or physician. Hepatitis B is controlled with tablets, not removed, so carriers usually stay under care for the long term. CION's team can plan surveillance for carriers, arrange tests through diagnostic partners and coordinate hepatology care.

Common questions about screening the family
Does every relative of a liver cancer patient need screening?
Not always. It depends on what caused the patient's liver disease. If it was hepatitis B or C, close relatives should be tested for the virus. If it was alcohol or fatty liver alone, relatives do not need virus testing because of the diagnosis, though their own health habits still matter.
Which blood tests should be on the checklist?
For hepatitis B, HBsAg shows a current infection and anti-HBs shows protection. Some doctors add anti-HBc to look for past contact. For hepatitis C, anti-HCV is the usual first test. Your doctor may add liver function tests for anyone found to carry a virus.
Do relatives need a liver scan as well?
Not usually as a first step. Relatives start with a blood test. Anyone found to carry hepatitis B or to have liver scarring may then be advised regular ultrasound scans, sometimes with an AFP blood test. A doctor decides who needs scans and how often.
Should young children be tested?
Yes, if a parent or sibling carries hepatitis B. Children of a carrier mother are at the highest risk. A child who tests negative and is unprotected can be vaccinated. Our page on testing children of a hepatitis B carrier covers this in detail.
What if a relative refuses to be tested?
Fear of stigma is common, especially around marriage and work. Explain that the test protects them and their own children, and that results are private. A doctor can sometimes have that conversation more easily than a family member. Nobody can be forced, so be patient.
My result is negative. Do I need to be tested again?
If you are negative and not protected, get the vaccine rather than repeat tests. If you are already protected, a repeat test is usually not needed unless your doctor advises it. Anyone with a new exposure to blood should ask their doctor.
Is this checklist the same as genetic testing?
No. These are blood tests for viruses, not for genes. Most liver cancer in Indian families is linked to hepatitis B, which is why virus testing comes first. Genetic counselling is only worth considering if a doctor suspects a rare inherited liver condition.
Can CION help our family work through the checklist?
Yes. CION's team can talk through who needs testing, arrange blood tests and scans through diagnostic partners, and coordinate hepatology care and surveillance for anyone who carries a virus. One helpline serves every CION centre, so the family can start with one call.
