Always get any unusual changes checked by a doctor…

If you have any worries at all about your child’s health it’s important to go to your GP as soon as possible. Be ready to give your doctor as much information as possible about your child’s symptoms: 

  • How the symptoms feel
  • When the symptoms happen
  • How long they have been going on for

Tell your doctor if you’re worried about cancer, so they can put your mind at rest. Read more about talking to doctors.
 

But try not to worry too much: All these symptoms can be caused by other conditions – and it’s very rare for children to get cancer. 

Can I get my child screened for cancer? 

Testing for cancer when you have no symptoms is called screening. There is no children´s cancer screening programme at present, however if you’re worried about cancer, talk to your doctor.
