Talking to kids about cancer

Talking about the diagnosis

When you first learn of a cancer diagnosis, you may feel shocked and overwhelmed. Among the many decisions you need to make will be when, where and how to talk to the children and young people in your life. However you decide to approach the conversation, try to be open and honest and leave kids with a feeling of hope.

When to tell your children

It's common to feel unsure of the best time to tell your children; often there may be no right time. You may wonder if you should tell them soon after you've been told yourself, or wait until you have more details about test results and treatment.

Although it is tempting to delay talking to your kids, try to tell them as soon as you feel able. Keeping the diagnosis a secret can be stressful, and your children will probably sense that something is wrong.

It's also a good idea to tell children if:

  • you think they may have overheard a conversation
  • they are scared by adults crying
  • they are shocked or confused by physical or emotional changes in the person who has cancer, especially if the person has symptoms such as frequent vomiting, weight loss or hair loss, or is admitted to hospital for immediate treatment
  • you notice changes in their behaviour.

It may be hard to decide how much information to share, particularly if you are waiting on test results. Your children don't need to hear everything all at once. If you don't know what treatment is required, just say so – but also assure your children that as soon as you have more information you will tell them. For example, "Dad is in hospital to have some tests. We're not sure yet what's wrong, but when we do know we will tell you."

Let children and young people know it's okay to have questions at different times, such as during treatment, when you are managing side effects and later during recovery, and to talk about how they feel at anytime.

Where to tell your children

Try to find some time when you won't be interrupted or have to rush off without answering all their questions.

Many people find that bringing up the topic while doing something else – like walking the dog or washing dishes – can help reduce the tension. This approach may be less intimidating than sitting the family down for a formal discussion.

Talking to children before bedtime or before an important event may not be a good idea. Ideally, you should tell them at a time and in a place where they are more likely to listen and take in the news.

Looking after yourself

Telling children and young people about a cancer diagnosis can be confronting and difficult. You may have trouble helping your kids deal with the news if you're struggling yourself. You may be facing both emotional and physical challenges and you will have to make many decisions, but you don't have to do this alone.

  • Wait until your initial feeling of shock has eased before attempting the conversation.
  • Talk to a few trusted adults beforehand – this will allow you to express your own feelings and start getting used to the news yourself.
  • Make a list of things that other people can do for you. Family and friends are often keen to help out, but usually need guidance on what to do.
  • Ask a friend to coordinate offers of help.

See more information about involving others. There are also many support services for people who are newly diagnosed with cancer – see contact details.

Deciding to tell them together or separately

Depending on the ages and temperaments of your children, you may decide to tell them individually or together. You may need to use different language because of their age. If you decide to tell them separately, try to tell them on the same day. Asking older children to keep the diagnosis a secret from younger siblings can add to their stress.

Deciding who should tell your children

Deciding on the person to tell the children is another thing to consider. In most cases, it is easier if the information comes from someone who is close to your children. Ideally, that will be the parent who has cancer, the other parent or both of you together.

However, this is not always possible. Another adult close to your children, such as a grandparent, aunt, uncle or friend, may be able to tell them or be there when you tell them. This may be particularly important if you're a single parent. You may also decide to break the news with the support of a member of your health care team, such as your general practitioner (GP) or social worker.

How to prepare

Parents often doubt their ability to find the right words and to answer the tricky questions their children ask. Take the time to plan what you'll say. Role-playing the conversation with your partner, friend, relative or the oncology social worker at the hospital can help you. It means you've spoken the words and perhaps dealt with some of the anxiety attached to those words before you talk with your kids. You can also practise in front of a mirror. This helps set the words in your mind.

Even if you practise what to say and you think you know how your kids will respond, be prepared for questions. You may not have all the answers, but it's okay to say you don't know or that you'll find out.

Work out beforehand how you might end the conversation. You could organise an activity, such as playing a game or going to the park, to help your children settle again. Older children may prefer some time alone. Also let your kids know that they can talk to you anytime they have questions or concerns.

If you end up blurting out the bad news or your child reacts differently to how you expected, don't worry. You'll have opportunities to talk about the diagnosis further as time goes on. Your children are unlikely to be affected by one discussion that doesn't go exactly to plan.

What children need to know

The following is a guide to what to cover in your initial conversation about cancer. These suggestions can help you adapt the information to the ages and reactions of your children.

Tell them the basics in words they can understand

You can break the news with a few short sentences explaining what you know so far and what will happen next.

Be clear about the name of the cancer, the part of the body that has the cancer and how it will be treated. To help explain cancer terms, you can:

Start with small amounts of information. Ask them what they want to know, and only answer questions that they ask – don't assume children will have the same concerns as you. You can give them more details later if they are interested. For younger children, accept that they may ask the same question several times. Each time you answer, they will absorb a little more information. Older children may be distant and quiet while they process the diagnosis.

Find out what they already know

Ask your children what they know about cancer and clear up any misinformation or myths (e.g. they might think that you can catch cancer, that their naughty behaviour caused the cancer or that everyone dies from cancer). Children get information from various sources, such as school, TV programs and the internet, and they may have their own ideas of what having cancer means. Parents can help guide their children towards accurate online information.

Be honest and open

Let them know if you don't know the answer to a question. Say you'll try to find out the answer from the doctor and let them know as soon as possible. Make sure you follow this through.

Tell them what to expect

Your children are likely to want to know what treatment will mean for them. If you are in hospital, who will drop them to school, make them dinner, take them to after-school activities? Reassure them that there will be a plan and you will let them know what it is.

Ask them if they want to tell anyone

Your children may want to tell their close friends, all the teachers, the whole class – or nobody.

Explain that it's helpful to share the diagnosis with a few key people, such as their main teacher and the school principal, as well as other important figures in their life, such as a music tutor or sports coach. Discuss ways to approach these conversations. See ideas about talking to the school.

Balance hope with reality

Tell kids that although cancer can be serious and going through treatment can be challenging, most people get better. Explain that with the help of the doctors and treatment teams, you (or the person with cancer) will be doing everything possible to get well.

Show your love and emotion

Tell your children that you love them, and show your love by hugging them, comforting them and making them feel valuable.

Some parents worry about crying in front of their children, but this is okay. It can be helpful for kids to know that strong feelings such as anger and sadness are normal, and expressing them can make people feel better. Being honest with each other about feelings can help your children cope.

Coping with kids' reactions

It's natural for children and young people to have lots of different reactions to a cancer diagnosis. Talking with them about their reaction gives you a chance to discuss ways of managing their emotions.


If your children cry, let them know it's a natural reaction. Holding them will help them feel secure. Let them know that they don't have to "be strong", and that feeling sad after a cancer diagnosis is common.


Some children will worry endlessly. It can be hurtful if they start to avoid or ignore the person who has cancer. Explain that the person with cancer is still the same person, despite any changes in appearance.

Children may also worry that they're going to be abandoned by their sick parent or by their well parent. Reassure them that they will always be cared for. Help your child deal with their concerns by giving them a chance to talk about their fears.


It is natural for children and young people to feel angry about the diagnosis as it means their lives could be disrupted.

Younger children may be annoyed if asked to play quietly. Older children may seem angry and uncooperative if asked to help out more. Both may be disappointed or upset if a planned holiday has to be postponed or cancelled.

No reaction

Sometimes children will appear not to have heard the news or do not react. You may be confused or hurt by this, especially if it took some planning and courage to share the diagnosis.

A lack of reaction isn't unusual – often the children are protecting themselves and need some time to digest the information. Or they may want to protect you from seeing how they are feeling. Remind them that they can talk to you about it anytime.

You may need to talk again if the situation or their behaviour has changed since you first talked. Sometimes, despite your efforts to help your children cope, they may struggle with the diagnosis. See below for services that can help children whose family members have cancer.

When another child has cancer

Your child may have a friend or cousin who has been diagnosed with cancer. While children may know someone with cancer, usually it's an adult in their life who is affected (e.g. a grandparent or teacher). It can be confusing and frightening for a child to learn that children can have cancer too.

Causes of cancer

Let your child know that childhood cancers are not lifestyle-related (e.g. caused by sun exposure or smoking), nor does a child get cancer because of naughty behaviour or a minor accident like a bump on the head. There's nothing anyone did to cause the cancer.

It's not contagious

Children need to feel safe around the child with cancer. Tell them that cancer can't be passed on to other people. If the sick child is in isolation, this is to protect the child from infection, not to protect everyone else from the cancer.

Most children get better

Like adults, children may worry that cancer means their friend will die. Reassure children that although cancer is a serious, life-threatening disease, the overall survival rate for children is now more than 80% 2. This can vary depending on the diagnosis, but most children will survive cancer.

Expect change

Explain that things will change for the friend. They may feel too tired to play or may be away from school a lot. They may have physical changes (e.g. hair loss, wheelchair). Encourage your child to focus on what hasn't changed – their friend's personality and their friendship.

Visit the hospital

Take your child to visit their friend in hospital if you can. It is confusing for your child if the person with cancer disappears from their life after diagnosis. They may imagine the worst. Let them know it's natural to wonder how to act and what to say, and that the more time they spend with their friend, the more they'll relax.

Keep in touch

Help your child maintain the relationship with their friend. They may not see each other as often and might not interact in the same way, but there are other ways to keep in touch. For younger children, this could mean making a get well card or a decoration for the hospital room. Older children may prefer to communicate by phone, email or social media.

Encourage feelings

Let your child know that it's okay to have lots of different emotions and that you have them too. They need to feel that they can approach you when they want to discuss what they're going through. It's also a good chance to discuss ways of coping with difficult emotions.

When a sibling has cancer

The siblings of children with cancer sometimes feel forgotten in the midst of a diagnosis. Parental attention is suddenly shifted, and daily routines, family roles and family responsibilities can change for a while.

Along with feelings of sadness, fear and anxiety, siblings may be struggling with more complicated emotions such as guilt, jealousy, resentment and anger. Because so much focus is on their brother or sister, they may feel that their needs do not deserve to be met and that they have no right to complain.

For many children and teenagers, fitting in with their peers is very important. This means they may feel embarrassed or self-conscious about their family now being different to other families. Some may be reluctant to tell their friends and teachers about the situation at home. If cancer changes how their brother or sister looks, they may feel embarrassed and shy away from being seen with their sibling.

You can help your children adjust to the changes in your family by talking openly and honestly. The tips listed above under When another child has cancer will help, but your kids may also be reassured to know the following:

It's not their fault

Check that siblings realise that they did not cause their brother or sister's cancer – even if they had been fighting with them or thinking mean thoughts about them.

What they can do

Explain that they can help support their brother or sister, and let them think about how they would like to do that. The sibling relationship is still important, so try to offer plenty of opportunities to maintain it. This may involve regular visits to the hospital and/or regular contact via phone, email or social media.

It is okay to have fun

Even though the child with cancer has to have a lot of attention at the moment, the needs of their siblings matter too. As far as possible, they should keep doing their own activities and have time for fun.

They are still just as loved

Explain to siblings that you may need to spend a lot of time and energy focused on the child with cancer, but this is out of necessity rather than feeling any less love for your other children. Naming the challenges and acknowledging the impact can really help.

They will always be looked after

Let them know that you will make sure someone is always there to look after them. Talk to them about who they would like that person to be if you can't be there yourself. 

If your child is diagnosed

Families often describe the days and weeks after their child's cancer diagnosis as overwhelming. Among the many confronting decisions they face is how to talk to the child about the illness.

Although the focus of this book is children affected by someone else's diagnosis, much of the advice will still be relevant. Children with cancer tend to feel more secure when the adults around them are open and honest – hiding the truth to protect a child may just lead to greater anxiety.

How much information you share with your child will depend on their age and maturity. Keep your initial explanations simple and take your cue from your child as to whether they want to know more. The first conversation will be followed by many others, so you will have the opportunity to give more detail as the need arises.

The paediatric oncologist, clinical nurse consultant and social worker at your child's hospital will be able to provide further guidance and assist you with these discussions. For younger children, some hospitals have child life therapists who teach children strategies to manage their illness and can help you explain the diagnosis and the treatment. If you have an older child with cancer, get in touch with one of the Youth Cancer Services. These are hospital-based services that offer specialised treatment and support to young people aged 15–25. Visit canteen.org.au/youth-cancer for more information.

Remember that your child's hospital team is there to support the family as well. The social worker can let you know what support services are available, particularly if you need to travel long distances for treatment.

Several organisations have developed resources for parents of children diagnosed with cancer. Visit the Victorian Paediatric Integrated Cancer Service, or Children's Cancer at Cancer Australia.

As much as possible, include your child in discussions about their treatment and recovery, and encourage them to ask questions. Older children and teenagers may want to seek out information themselves. You can let them know about reliable, age-appropriate resources such as CanTeen and Redkite (see contact details and other support services).

The right words to use

It's often hard to find the right words to start or continue a conversation. The suggestions below may help you work out what you want to say. Although these are grouped by age, you may find that the ideas in a younger or older age bracket work for your child. See tips on how to answer specific questions.

About cancer

“Mummy is sick and needs to go to hospital to get better. You can visit her there soon.”

“I have an illness called cancer. The doctor is giving me medicine to help me get better. The medicine might make me feel sick or tired some days, but I might feel fine on other days.”

“We’ve had some bad news. I’ve got cancer. We don’t know what we’re dealing with yet, but I’m going to have surgery so that the doctors can have a look and find out.”

“You know that Mum has been sick a lot lately. The doctors told us today that the tests show she has cancer. The good news is that she has an excellent chance of getting better.”

“The doctors say Dad has a problem with his blood. That’s why he’s been very tired lately. The
illness is called Hodgkin lymphoma. Dad will have treatment to make him well again.”

“Lots of people get cancer. We don’t know why it happens. Most people get better and we expect
I will get better too.”

To clear up misinformation about cancer

“Sometimes girls and boys worry that they thought or did something to cause cancer. No-one can make people get cancer, and we can’t wish it away either.”

“How do you think people get cancer?”

“We can still have lots of kisses and cuddles – you cannot catch cancer from me or from anyone who has it.”

“We can still have lots of kisses and cuddles – you cannot catch cancer from me or from anyone who has it.”

“Cancer is a disease of the body that can be in different places for different people.”

“Even though your friends at school might say that cancer is really bad and I will get very sick, they don’t know everything about this cancer. I will tell you what I know about my cancer.”

“There are lots of different types of cancer and they’re all treated differently. Even though Uncle Bob had cancer, it might not be the same for me.”

“The doctor doesn’t know why I got cancer. It doesn’t mean that you’ll get cancer too. It’s not contagious (you can’t catch it) and the cancer I have doesn’t run in families.”

“Even though Grandma has cancer, the doctors say she’ll probably be okay because she was diagnosed early.”

To explain changes and offer reassurance

“Mummy needs to go to the hospital every day for a few weeks, so Daddy will be taking you to preschool/school instead.”

“Grandpa is sick so we won’t see him for a while. He loves your pictures, so maybe you can draw me some to take to hospital.”

“Mummy has to stay in bed a lot and isn’t able
to play, but she can still cuddle you.”

“The doctors will take good care of me. I will have treatment soon, which I’ll tell you about when it starts.”

“Even though things might change a bit at home, you’ll still be able to go to tennis lessons while Dad is having his treatment.”

“Mum is going to be busy helping Grandma after she comes out of hospital. There are ways we can all help out, but mostly things won’t change for you.”

“Things will be different while Dad’s having treatment, and when I can’t drive you to soccer
training, Annie will drive you instead.”

“After my operation, there are a few things I won’t be able to do for a while, like lifting things and driving. Our friends are going to help by dropping off meals.”

“What things would you like to help with at home?”

“If you think of any questions or have any worries, you can come and talk to me. It’s okay if you want to talk to someone else too.”


Involving others

There are several ways to ensure kids hear a consistent message from people who are involved in their lives.

Tell key adults

Share the diagnosis with other people who talk with your kids (grandparents, friends, the nanny, babysitters) and tell them what you plan to say to your children so that you all communicate the same message.

Talk to other people who have cancer

Often the best support and ideas come from people who've already been there. You'll realise you're not alone and you can ask them how they handled things (see support services).

Ask a professional

Get some tips from the oncology nurse or social worker, psychologist or other health professionals at the hospital.

Involving the school or preschool

Many parents or carers wonder if they should tell the school. If things are unsettled at home, school can be a place where kids can be themselves with their friends and carry on life as normal.

When the school is aware of the situation at home, staff will be more understanding of behaviour changes and can provide support. In fact, school staff are often the first to notice shifts in a child's behaviour that may indicate distress. A cancer diagnosis in the family can also affect academic performance, so the student may be entitled to special provisions, which can be particularly important in the final years of high school.

Ways to involve the school include:

Tell the principal, the school counsellor and your child's teachers. They may know of other people in the school community affected by cancer and this may influence your child's understanding of the disease (e.g. a parent or a child at the school may have died of cancer).

  • Let relevant staff know what your child has been told about the cancer and what they understand cancer to mean, so staff can respond consistently.
  • Ask the school to let you know of any changes in behaviour or academic performance. Ideally, a particular staff member, such as the class teacher, student wellbeing coordinator or year adviser, can provide a regular point of contact with the student. However, request that teachers don't probe – some well-meaning members of staff might misinterpret your kid's behaviour and unintentionally make them feel uncomfortable (e.g. the teacher may ask if they're okay when they're happily sitting on their own).
  • If you feel concerned about how your child is coping, ask the principal whether your child could see the school counsellor.
  • Sometimes other children can be thoughtless in their comments. Check with the teachers and your child to see how other children are reacting so that negative behaviour can be addressed appropriately.
  • Ask a parent of one of your child's friends to help you keep track of school notes, excursions, homework and other events. When life is disrupted at home, children may feel doubly hurt if they miss out on something at school because a note goes missing.
  • Ask the principal whether the school could organise for services that support students to visit the school. For primary schoolchildren, Camp Quality has developed an educational puppet show to help young students learn about cancer in a safe, age-appropriate way. For more details, call 1300 662 267 or visit campquality.org.au. For older children, CanTeen has a cancer awareness program called When Cancer Comes Along. To find out more, contact CanTeen on 1800 234 007.
  • Explore what special provisions might be available for exams or admission into university.

For more ideas about how your child's school can help, see Cancer Council's book Cancer in the School Community: A guide for staff members, which explains how school staff can provide support when a student, parent or staff member has cancer.

Answering key questions

Q: Are you going to die?

This is the question that most parents fear, but often it doesn't mean what you think. For example, younger children may really mean "Who is going to look after me?" Older children may be wondering, "Can we still go away during the school holidays?"

Try to explore the question by asking, "Do you have something in particular you're worried about?" or "What were you thinking about?" You can explain that treatments are improving constantly. If your child knows someone who has died, let them know that there are many different types of cancer and everyone responds differently.

A: "We don't expect that to happen, but I will probably be sick for a while. Sometimes it makes me sad, and I wonder if you get sad too."

Q: Was it my fault?

Some children may ask you directly if they caused the cancer, while others worry in silence, so it's best to discuss the issue.

A: "It's no-one's fault I have cancer. Scientists don't know exactly why some people get cancer, but they do know that it isn't anything you did or said that made me sick."

"You did not cause this cancer. There is nothing you could have said or done that would cause someone to have this illness."

Q: Can I catch cancer?

A common misconception for many children (and some adults) is that cancer can spread from person to person (contagious). This belief may be reinforced because when patients have chemotherapy they need to avoid contact with people who are sick. This is to protect the person with cancer from picking up infections, not to protect everyone else.

A: "You can't catch cancer like you can catch a cold by being around someone who has it, so it's okay to hug or kiss me even though I'm sick."

"Cancer can spread through the body of a person with cancer, but it can't spread to another person."

Q: Who will look after me?

When family routines change, it's important for children to know how it will affect their lives: who will look after them, who will pick them up from school, and how roles will change. Try to give them as much detail as possible about changes so they know what to expect. For older children, it's worth asking them what arrangements they'd prefer.

A: "We will try to keep things as normal as possible, but sometimes I may have to ask Dad/Mum/Grandpa to help out."

Q: Do I have to tell other people about it?

Your children may not know who to tell about the cancer or what to say. They may not want to say anything at all. It helps to explore their feelings about talking to others.

If you're planning to inform teachers, or the school counsellor or principal, talk to your kids first. Teenagers and even younger children may be reluctant for the school to know, so explain the benefits of telling the school and then chat about the best way to approach the discussion. Ask if your teenagers want to be involved in talking to key teachers or the principal with you – this way they are part of the agreement made with the school.

A: "You can tell your friends if you want to, but you don't have to. People we know may talk about the diagnosis, so your friends might hear even if you don't tell them. Many people find it helps to talk about the things that are on their mind."

"Do you worry about how your friends will react or treat you?"

"I need to let your teachers know so they understand what's happening at home. We can talk about who to tell and how much we should say."

Q: Is there anything I can do to help?

Answering this question can be a delicate balance. Letting kids know that they can help may make them feel useful, but it's important that they don't feel overwhelmed with responsibility. Some parents may feel hurt if their children don't ask how they can help, but it's common for children not to think to offer.

A: "Yes, there are lots of things you can do to help. We will work out what those things can be, and what will make things easier for everyone. Is there something in particular you would like to do?"

"Some help around the house would be good, but it's important that you keep up with your schoolwork and you have some time for fun and for seeing your friends."

Key points

  • Discuss the diagnosis with trusted adults first if you need to.
  • Ask for practical and emotional support from relatives, friends or colleagues.
  • Work out the best time to talk to your children.
  • Decide who you want to be there with you.
  • Tell your children what has happened.
  • Explain what is going to happen next.
  • Assure them they will continue to be loved and cared for.
  • Approach the initial conversation as the first of many.
  • Let them know it's okay to feel scared or worried, and talking can help.
  • End the discussion with expressions of hope.
