Cancer

Childhood cancer is a group of cancers that affect children and teenagers, usually younger than 15 years.
If your child has been diagnosed with cancer, there will be physical, emotional and practical challenges ahead. You may have a lot of different feelings. Childhood cancer can disrupt your child's and your family's lives. There is a lot of support and information out there to help both you and your family.
The most common childhood cancers are:
Scientists have made big progress in cancer research. Treatments have improved and many cancers are now treatable. Survival rates have improved for many different cancers.
Your child's outlook depends on what kind of cancer they have and what stage their cancer is when diagnosed.
When you first tell your child they have cancer, keep your explanation simple. You can tell them the name of the cancer, where it is in their body and how it will be treated.
For example, "You have a lump growing inside your leg that shouldn't be there. It is called cancer. You will have an operation to take it away. Afterwards, your doctor will give you medicine to make sure the lump does not come back."
How you tell your child and how much information you share depends on their age, development and maturity. You can ask your child's healthcare team for guidance on how to talk to your child.
Here are some tips to support your child when discussing their diagnosis:
Remember, all children respond differently. There is no right or wrong way for them to react. It is normal if your child responds with anger, denial or even silence.
Not telling your child about a cancer diagnosis can make things worse. It may make them anxious (Opens in new tab) because they will probably sense something is wrong. It is better for them to discuss it with you than to find out from someone else.
The Cancer Council's book Talking to kids about cancer (Opens in new tab) explains how to discuss cancer with your children.
Here are some tips to support your child in coping with a cancer diagnosis:
You might notice some changes in your child's behaviour. They may have trouble being away from you, or cry and scream more than usual. They may not cooperate during tests.
Some children may 'regress'. They will act younger than they are. They might stop doing things they knew how to do before. They may become withdrawn and not want to play as much. You may also notice changes to their sleeping patterns and toileting.
Many hospitals provide education and activities for children with cancer. They may also have an educational psychologist and counsellor to help them during their time in hospital.
How you help your child cope with cancer treatments depends on their age, development and what they understand. Your child's healthcare team will guide you on how best you can support them.
Here are some general tips:
Your child's cancer and treatment will physically affect your child. Discuss with your child's doctor which side effects your child may develop. This way you can prepare your child. You will also have strategies to manage these side effects.
If your child has a weakened immune system because of their treatments, they may need a mask or strict hygiene habits to protect them from infections.

You can support your child as they recover from cancer by being aware of their physical and emotional needs. As you celebrate their recovery, new challenges may come along.
Your child's cancer treatments may have lasted several years. During this time, they may have missed out on reaching important developmental milestones. In addition, your child's treatments can severely affect your child. They can cause ongoing health complications.
It may not be possible for things to go back to exactly how they were before your child had cancer. Your child may need ongoing therapies, such as physiotherapy or occupational therapy.
Your child will also need to go back to school or childcare. Depending on their age and how their cancer has affected them, this can cause some social anxiety and other challenges.
Your child may also feel worried that the cancer will come back. They may not have the skills to cope with these feelings and may develop difficult behaviours. Some children develop post-traumatic stress disorder (PTSD).
Here are some tips to help your child cope:
How you support your other children depends on their age, development and temperament. Having a brother or sister go through cancer can be an overwhelming and lonely time for your other children. Family relationships may be different to usual.
Your children may feel resentful, angry or afraid. They may struggle to express and process their emotions. Their behaviour might change.
Here are some tips to support your other children:
Your child's cancer team can guide you on how best to support your children. They will consider your personal circumstances.
