Most parents' first instinct, when a cancer diagnosis comes into a family, is to protect the children by saying as little as possible. It comes from a good place. But in our experience, sitting with a lot of families through exactly this moment, it usually backfires. Children sense far more than adults give them credit for — a changed routine, hushed phone calls, a parent's altered appearance after chemo — and when nobody explains it, they tend to fill in the blanks themselves, often with something scarier than the truth.
You don't need one perfect conversation
There's a lot of pressure around getting "the talk" right, as if it's a single event. It isn't. It works better as an ongoing, honest thread — a first conversation that gives the basic facts, followed by smaller conversations as things change or as the child has more questions. Give yourself permission to not have every answer in the first sitting.
Use the word "cancer"
It's tempting to soften it — "Mama is a bit unwell," "Papa has to rest a lot now." Children, especially school-age ones, often hear the real word from somewhere else eventually — a classmate, an overheard adult conversation — and discovering they were kept from the actual word can feel like a bigger betrayal than the diagnosis itself. Using the real word, at an age-appropriate level of detail, tends to build more trust than it breaks.
Match the detail to the age, not the whole truth to a single sentence
A five-year-old needs to know that a parent is sick, that doctors are helping, and that it's not their fault and not contagious. A twelve-year-old can handle more — what the treatment involves, what changes to expect at home, roughly how long things might take. A teenager often wants to know almost everything, including the harder parts, and may feel patronised if you withhold too much.
Expect ordinary reactions, not dramatic ones
Some children cry immediately. Many don't — they ask a practical question ("will you still come to my school function?") and then go back to playing ten minutes later. This isn't a lack of understanding; it's how children often process big news, in small pieces, over time. Don't read the absence of visible distress as the absence of impact.
Keep as much of their routine intact as you can
School, friends, extracurriculars, bedtime — the more normal you can keep the surrounding structure of a child's life, the more secure they tend to feel, even while one part of life has changed significantly. If a home nurse or attendant is now part of the household routine, a short, simple explanation of who they are and what they do (not a medical explanation, just a practical one) helps a lot.
It's fine to say "I don't know"
Children ask questions no one can fully answer — "will you get better?", "will you die?" It's tempting to over-reassure with certainty you don't have. A more honest answer is something like: "The doctors are doing everything they can, and we're going to take this one step at a time together." It doesn't promise an outcome, but it does promise presence — which is usually what the question is really asking for.
If a conversation like this feels like more than you can navigate alone, that's a completely normal thing to want support with. Our counselling team works with families specifically on this — not to script what you should say, but to help you find your own honest way of saying it.
