Does chemotherapy treat childhood cancer?

It may be the main treatment for cancers of the blood or lymphatic system, or one part of care for a solid tumour. Depending on the diagnosis, chemotherapy can be used before or after surgery and may be combined with radiotherapy, targeted treatment or immunotherapy.

Childhood cancer is a group of different diseases rather than a single illness. The care team uses the cancer type, where it is in the body, laboratory features and the child's age, growth, organ function and previous treatment to design a plan.

Doses are carefully calculated and treatment is usually organised into cycles or phases. The paediatric oncology team also plans medicines and nutrition support to reduce or manage side effects. Blood counts and organ function may be checked before treatment continues.

Keep the family's emergency contact instructions close and check with the team before giving vitamins, herbal products or non-prescription medicines. Give prescribed supportive medicines as directed, and report problems with eating, drinking, pain, bowel movements, sleep or mood.

Ask the care team how school, play, visitors and food safety should be handled during periods of lower immunity. Age-appropriate explanations from parents and child-life or psychology professionals can help a child know what to expect. Siblings may also need clear information and emotional support.

Call the treatment service without delay for a fever at or above the threshold provided by your child's team, shaking chills, trouble breathing, unusual sleepiness, confusion, uncontrolled pain, repeated vomiting, inability to drink, reduced urination, unexpected bleeding or a problem with a central line. Do not give fever-reducing medicine first unless the oncology team has told you to do so.

Parents and carers can ask which medicines the child will receive, how each phase helps, what side effects are expected, whom to call overnight, whether fertility preservation should be discussed, and how follow-up will monitor growth, learning and organ health.
