Talking to children about cancer
Explaining a Parent's Scan — to Your Children
Children sense when something is wrong, even if no one tells them. A simple, honest conversation — shaped for their age — protects them far more than silence does.
Medically reviewed by Dr. C. Raghavendra Reddy, Medical Oncologist, MBBS (Gold Medal) · DNB · DM (Medical Oncology, Gold Medal) · Last reviewed September 2026
- Silence does not protect them — Children fill gaps with imagination, and what they imagine is often more frightening than the truth.
- Age shapes what you say — A five-year-old and a fifteen-year-old need different words for the same news.
- One conversation is not enough — Children process news slowly. Short, repeated conversations work better than one big talk.
- You do not need all the answers — Saying 'I don't know yet, and I will tell you when I do' is an honest and reassuring answer.

Children understand more than adults expect. Telling them the truth — simply, at the right level for their age — protects them more than silence does. Start with what is happening now: Amma or Nanna is going for a scan to help the doctors understand what is in their body. That is enough for younger children.
CION offers PET-CT in Hyderabad from Rs 10,499 — among the lowest published prices in the city, with no hidden charges. Indicative price, as of September 2026.
What do you say at each age?
Under 5 — keep it concrete and calm
Say: 'Amma's body has something the doctors need to look at carefully. She is going to a special machine that takes pictures inside her body. She will come home afterwards.' Do not name the illness. Focus only on what is happening today. Young children need two things: that you are there, and that they are safe.
Ages 5 to 8 — name it simply
Say: 'Nanna has an illness called cancer. The doctors need to do a scan — a special picture of the inside of his body — to help decide how to treat him. Cancer is not something you can catch. It is not because of anything you did.' If they ask whether he will be okay: 'The doctors are working hard, and I will tell you everything they tell us.'
Ages 9 to 12 — be more specific
Say: 'The scan is called a PET-CT or MRI. It shows the doctors where the cancer is and how the treatment is working. We will tell you what we learn.' Children this age often look things up online. Tell them they can bring you anything they read and you will go through it with them.
Teenagers — include them properly
Teenagers often know more than parents realise, and being excluded is harder than the news itself. Say: 'We want to keep you properly informed. Nanna has a scan this week and we will share the results with you.' Give them a role if they want one — coming with you, staying with younger siblings. Having something to do helps.
What helps before you sit down to talk?
- Choose a calm time — not the morning of the scan or just after a difficult appointment.
- Sit in a small group. A roomful of relatives listening makes children shut down.
- Turn off the TV and put phones away so the children feel the conversation matters.
- Decide in advance who will answer a hard question, so no one is caught unprepared.
- Tell siblings together. Children talk, and the one told last feels left out.
- Tell the class teacher that a conversation has happened, so they can watch for changes in mood or schoolwork.
- Remind children that cancer is nobody's fault — including theirs.

Should my child come to the scan?
For children under ten, a scan waiting area is usually a long, anxious wait in an unfamiliar place. Unless your child strongly wants to come, it is often kinder to leave them with someone they trust and tell them what happened when you return.
Teenagers are different. Being excluded can feel like being shut out of the family. If they want to come, let them — waiting together often eases anxiety rather than adding to it.
Ask your child what they would prefer. Their answer tells you what they need right now.
How do you answer questions you cannot answer?
You will be asked questions you do not have answers to. 'Will Amma be okay?' is the one every parent dreads. The honest answer: 'The doctors are working to help her. I do not know exactly what will happen yet. I will tell you everything I learn.'
Do not make promises about outcomes. Children remember them. If things go differently, a broken promise adds another hurt on top of an already difficult time.
If a question is too painful to answer in the moment, say: 'That is important. Can we talk about it this evening?' Then come back to it. Returning matters.
Did you know?
Children who receive honest, age-appropriate information when a parent has cancer show fewer signs of long-term anxiety than children kept in the dark — even when the news is serious.
What children find hardest is not the truth. It is sensing that something is being hidden from them.

Common questions
Frequently asked questions
My child asked if their parent is going to die. What do I say?
This is the question most parents are most afraid of. The most honest answer: 'The doctors are working hard to help Amma. I do not know exactly what will happen, and neither do they yet. What I do know is that we are all together and I will always tell you the truth.' Do not say 'she will be fine' if you cannot know that. Children who receive a false assurance and then face a different outcome often carry that hurt for a long time. Sitting with uncertainty together is harder in the moment, but kinder.
Should I tell the school?
Yes. Tell the class teacher, and for secondary school students the year head as well. You do not need to share medical details. 'A parent is seriously unwell and the family is going through a difficult time' is enough. A teacher who knows can watch for withdrawal, a drop in concentration, or behaviour changes that might otherwise be misread. Most schools also have a counsellor who can check in with your child.
Our joint family wants to keep it secret from the children. What do we do?
The instinct to protect children from difficult news is loving — and very common in Indian families. The problem is that children in a joint household are surrounded by worried adults lowering their voices, and they notice. When they are not told what is happening, they tend to assume something worse, and they lose trust when they find out the truth was kept from them. A gentle conversation with elders may help: the children will hear something regardless. It is better they hear it from us, in words we choose.
My child has not asked a single question. Is that normal?
Yes, and it is more common than people expect. Some children go very quiet when they are processing something difficult. Check in gently a few days later: 'Is there anything about Amma's scan you have been wondering about?' Give them an opening without pressure. Some children find it easier to talk at bedtime or in the car, when they are not looking directly at you. If the quiet lasts more than a couple of weeks, or if you notice changes in sleep or schoolwork, mention it to your treating team.
How do we keep updating the children as treatment goes on?
Short and regular works better than one large conversation every few months. After a scan result or a treatment decision, tell the children before they overhear it from someone else. You do not need to share every detail. 'The scan showed the same as before, so the doctors are continuing the treatment' is enough for a young child. The habit of brief, honest updates means children stop worrying about what is being hidden and learn to trust that you will tell them what they need to know.
