A brave teenager who overcame long-term cancer has been banned from attending her high school ball after being told she has had too much time off school.

English teen Alex Dallas has battled cancer since she was 4 and after a 12-hour operation to remove a deadly tumour she was hoping to make her dream of attending the ball come true.

The 16-year-old bought a $680 custom-made dress as well as spending hundreds of dollars on hair and make up.

However, the Year 11 student was told she wouldn't be able to join her fellow classmates at the ball.

"The prom's the thing you look forward to from when you're 11," she told the Mirror. "It makes all the stress of exams worth it."

Ormiston Bolingbroke Academy said the decision was made in the best interests of Alex's health and safety.

"We wanted to make sure attending the event was in the best interests of this student, and indeed her fellow students.

"Because she had not been in to school for six months, we asked her to come in for one hour a day over a two-week period before the prom, so we could make an assessment and so she could interact with other students.

"Unfortunately she did not do so and so we reluctantly took the decision that it would not be right for her to attend the event."

Alex's mother Sam Mattison was furious at the school's stance, telling the Mirror the reason is a cop out.

"My daughter's been through hell and she wanted to finish school on a high with all her friends, most of whom she's known since nursery," Mattison said.

"She's 4ft 5 and 4 stone, she's not a threat. She wanted to be treated like every other child and she's been denied her big night.

"The school have severely let her down. They say it's a safeguarding issue and asked 'what if she locks herself in a toilet?'

"She needed this, she's just had her head sliced open in a massive operation. She was desperate to have everything sorted by her prom date."
