One of the key advantages of proton beam therapy over conventional radiotherapy is that it is more targeted. It does less damage to the healthy tissue around the tumour and the rest of the brain. This means it causes fewer side-effects, however, there are a few side-effects which are not uncommon.
The following side-effects are usually temporary and often disappear after treatment has finished:
Longer-term effects after PBT treatment in children can include hearing loss, which can be severe, and cognitive impairment, particularly in thinking speed and understanding language.
Hormone levels can be affected in up to 55% of children, with growth hormone being the most commonly affected.
However, all these effects are also possible side-effects of conventional radiotherapy. Ask your radiotherapy team about any side-effects you or your child may experience.
No, you do not need to take special precautions when you leave the hospital - it is safe to be around others, including children.
