The short answer
Even young children can sense when something is wrong, so it helps to be honest rather than pretend everything is okay. Children of all ages need reassurance that they didn't cause the cancer, that it doesn't always mean death, and that they'll be cared for. Give kids time to ask questions and share feelings, and adjust how you talk based on their age.

The full explanation.
Be honest, even when it's hard
Even though your children will be upset when they learn about your cancer, don't pretend that everything is okay. Even very young children can sense when something is wrong. They'll notice that you don't feel well, are away from home more, or can't spend as much time with them as before. Children as young as 18 months old begin to notice what's going on around them.
It's important to be honest. Telling the truth is better than letting them imagine the worst. Give your kids time to ask questions and express their feelings.
What children of all ages need to know
About cancer:
- Nothing your child did, thought, or said caused you to get cancer.
- Having cancer doesn't mean you'll die from it. In fact, many people live with cancer for a long time.
- Your child can't make you well, but there are ways they can help you feel better.
- Scientists are finding many new ways to treat cancer.
About living with cancer in the family:
- Your child is not alone—other children have parents who have cancer.
- It's okay to be upset, angry, or scared.
- Your child can't change the fact that you have cancer.
- Family members may act differently because they're worried about you.
- You will make sure your children are taken care of, no matter what happens.
About what they can do:
- They can help by doing nice things like washing dishes, cleaning their room, or drawing you a picture.
- They should still go to school and take part in sports and other fun activities.
- They can talk to other trusted adults for support, such as teachers, family members, and religious or spiritual leaders.
How kids may react
Children can react to cancer in many different ways. For example, they may:
- be confused, scared, lonely, or overwhelmed
- feel guilty and think something they did caused your cancer
- feel angry when asked to be quiet or do more chores
- miss the attention they're used to getting
- behave as they did when they were much younger
- get into trouble at school or home
- be clingy and afraid to leave the house
Talking with teens
If you have a teenager, remember they're at a time when they're trying to become more independent from their parents. Try to get them to talk about their feelings and ask questions. Tell them as much as they want to know about your cancer. Ask them for their opinions and, if possible, let them help make decisions.
Teens may want to talk with other people in their lives. Friends can be a great source of support, especially those who also have a serious illness in their family. Other family members, teachers, coaches, and spiritual leaders can help too. Encourage your teenage children to talk about their fears and feelings with people they trust.
Talking with adult children
If you have adult children, your relationship with them may change now that you have cancer. You may:
- ask them to help with health care decisions, paying bills, or taking care of the house
- ask them to explain medical information
- need them to go to the doctor with you or pick up medicines
- rely on them for emotional support
- feel awkward when they help with your physical care
For some parents, it's hard to ask for comfort and care from grown children. But it's important to talk about cancer with your family, even if they get upset. Try to include them when talking about your treatment, and let them know the choices you'd like them to make about your care in case you're too sick to decide yourself. Recognize that this may be hard for them too, as they adjust to your illness.

How this page was created
Cancer Explained does not originate medical claims. Every page restates guidance already published by the National Cancer Institute, the CDC, the USPSTF and the FDA, in plain language, with the source cited so you can check the original yourself. AI does the translating and organizing; automated checks test claims, citations, clarity and safety before anything publishes. We do not employ clinicians and do not intend to — our work is translation and navigation, not clinical judgment. Nothing here is personal medical advice, and no page can account for your particular situation.
Editorial status — Source checked. This page was written with AI assistance and checked line by line against the sources listed on it. That confirms the sources support what the page says. It is not a medical review, and it does not confirm the page is complete or right for your situation.
General education. Low-risk educational or organizational content. Medical facts are cited to authoritative sources.
Human medical review: not completed. Pages here are not signed off by a clinician before they publish. That is not an oversight we are quietly working around: we restate published guidance and cite it, so the authority belongs to the source rather than to us, and every page names where its claims come from — you can verify us instead of trusting us. Where a volunteer clinician has reviewed a page, their name and credentials appear on it; where no name appears, no clinician has checked it. We are glad to have reviewers and are recruiting them, and we do not hold pages back waiting for one. Use this site to understand your situation and to ask better questions of the people treating you.
