The family of cancer battler Jayden Stone are back in Perth after the toddler's months of treatment in the US, but face an anxious wait to see if the aggressive disease will reappear.
Jayden, 2, was treated in Chicago for an atypical teratoid rhabdoid tumour - a childhood cancer that affects just three in a million in the US and has a 10 per cent survival rate.
Jayden's mother Leisl Stone said Jayden was happy to be back in familiar surroundings after they arrived yesterday.
"The care and facility (in Chicago) were worth every effort," she said.
In the US he received proton beam therapy, which is not available in Australia, and has fewer side effects. A recent scan showed no trace of the tumour but the toddler will have more chemotherapy in Perth to try to prevent the cancer recurring.
"This type of cancer is so aggressive it often grows back in the following six months," Mrs Stone said. "You are not out of the woods until they are eight, nine, 10 years old."
