Active surveillance for childhood brain and spinal cord tumours

Last medical review:

Active surveillance means that the healthcare team watches the tumour closely rather than giving other treatments right away. They will use tests and exams to see if a tumour is growing or spreading. Other treatments are given if there are any signs that the tumour is growing or there is a higher risk that the tumour will progress.

This approach helps avoid side effects that can happen with treatments such as surgery or radiation therapy. There is no evidence so far that active surveillance reduces long-term survival compared to other treatments. And there is no evidence that active surveillance has other negative effects if or when your child starts treatment.

Active surveillance may be a treatment option for some types of low-grade brain and spinal cord tumours.
