The year two student at St Georges Basin Public School began to notice some swelling in his eye late last year.

When it still hadn't gone away a few days later, his mum Melanie lifted back his eyelid and immediately discovered a growth.

Within days Jett was diagnosed with Rhabdomyosarcoma, an aggressive form of childhood cancer.

Jett had eight months of chemotherapy and six weeks of radiation, missing almost three months of schooling.

However, between his classroom teacher Natalie Heywood and his Fight Cancer Foundation teacher, Trish, Jett was able to stay on top of his homework and has settled back into his classroom.

Jett's mum Melanie Waldron said both teachers were crucial in guiding Jett through the tough times.

"They were both amazing," she said.

"I especially couldn't have done it without Nat; she's part of the family now."

Mrs Heywood said her young student has inspired her.

"He's just incredible, he's so resilient and the most wonderful little boy," she said.

While Jett lost his hair during treatment, his family and friends came together in support, shaving their own hair too.

Kurt from Barber 2 You provided his services and John from The Point Pizzeria made sure to keep the pizza flowing.

Ms Heywood and Jett's classroom buddies hosted a party recently to welcome Jett's hair growing back.

He'd been sporting a cap through treatment but the time had come to celebrate.

"Jett came to me the night before and said 'I think I want to take my hat off at school'," Melanie said.

"He asked me to tell Mrs Heywood and she was so good. The very next day they had cake and lollies and counted down from 10 to do the big reveal."

Jett's treatment has finished. While he's seeing a pediatrician and oncologist alternatively every six weeks, his scans are clear.

A proud Parramatta Eels supporter, Jett is also now an ambassador for Footy Colours Day.

The event encourages Australians to wear their footy colours and make a donation to Fight Cancer Foundation. All funds raised contribute to education support programs for young cancer patients so they can maintain to same education level as their peers, such as the one that helped Jett.

St Georges Basin Public School will be hosting its own Footy Colours Day next month. Students will get into the spirit of the day, donning their favourite team's jersey and donating a coin or two.

As for Jett, there's only one colour he'll be sporting - blue and gold. Just last weekend he met Eels star Mitch Moses and ran onto the field before a game.

All businesses, schools and community groups are encouraged to hold their own Footy Colours Day on an day in September. Find more information fightcancer.org.au
