A six-year-old boy from Birmingham has returned to school permanently after 18 months of chemotherapy.
Bobby Humphries from Yardley was diagnosed with a brain tumour aged just two.
His intense treatment means he has missed dozens of lessons at St Thomas More Catholic Primary School.
At times, he has been forced to undergo treatment in the morning and return to lessons in the afternoon.
Brain tumours kill more children and adults under the age of 40 than any other cancer - yet research into them gets only around 1% of all funding.
The national charity Brain Tumour Research says that needs to change.
Although his chemotherapy has now finished, Bobby's battle with cancer is not completely over and there is still a risk that the brain tumour could re-grow again.
He is due to have an MRI scan later in September and his family are hopeful that it will show that his condition has stabilised.
