Explaining cancer to your children

You are a parent before you are a cancer patient.
Explaining the changes, challenges and realities of your diagnosis to your child(ren) and supporting them through it can be daunting and difficult. We have some tips and resources to make it easier...

Telling your child(ren)

It is your choice if you tell your children about your cancer diagnosis and treatment or not. This can be a difficult and sometimes distressing experience. Some families prefer not to include the children, while some families find the honesty and openness hugely beneficial.

Make sure you set aside time to tell them, without expectations to go anywhere, or do anything demanding before or after. Leave enough time to allow for questions and big emotions to be expressed.

Choose a place where you all feel comfortable and where it is safe for big feelings to be expressed.

Use language that is appropriate and accurate (some of the books and resources below can help with this).

Don't be surprised if they do not react as you expected. Some children will need time to process what they have been told and their questions or emotional response may come later (even days or weeks later!).

Let them know they can ask questions and where you suggest they ask them. You might encourage them to come directly to you, or to a trusted adult, such as a grandparent or teacher, if they prefer.

It may be helpful to inform their nursery or school, in case they exhibit any behavioral or mood changes. This will allow the staff to adjust their provision to best support your child(ren).

Consider using books, videos and other resources to support understanding. These should be age appropriate, and will ideally support what you have already told them. We have a few suggestions to get you started...
