SCOTT Doyle has every reason to be angry at life after losing an arm to cancer, but says: "in some ways, I'm glad it's happened".

Despite having treatment for osteosarcoma, a type of bone cancer, the teenager is far from bitter about his circumstances.

"This has allowed me to get a little more awareness out about osteosarcoma," the 14-year-old said. "It's losing an arm to save lives."

Scott has told his story "hundreds of times" since The Courier-Mail first interviewed him in March, two weeks after his left arm was amputated. This week, he was nominated for a Pride of Australia award in the Child of Courage category.

He wants other teenage boys to avoid the same mistake he made, keeping the growing lump in his arm a secret from his mother for weeks, not wanting to worry her.

By the time he was diagnosed in January, the lump had grown to the size of an orange, too big for doctors to save his arm, and the cancer had spread to his lungs.

He is still having five days of chemotherapy every three weeks at the Royal Children's Hospital in Brisbane.

"People never stop asking about my story and I never stop telling them," Scott said. "I feel that me being able to get my story out is making a difference."

Rather than dwell on his situation, when he's not having chemotherapy, the Dalby teenager promotes blood donation and children's charities, trying to support the people who first helped him.

Tomorrow, he will be the face of a teddy bears' picnic at Eagle Farm Racecourse to raise money for the Children's Health Foundation which funds research and support programs at the RCH.

Accompanying Scott will be two of his closest companions during his cancer journey - sister Lilly, 9, and a teddy bear, dubbed Major Peter Wilson, named after a cancer specialist at the hospital.

Scott's mum, Andrea Bowkett, said promoting childhood cancer awareness had given Scott "something positive to focus on" during his illness.

After months of chemotherapy, the family received positive news this week.

"There's no traces of cancer in his bones and the tumours in his lungs are getting smaller. The cancer is responding to the chemo really well," Ms Bowkett said.

The teddy bears' picnic will run from 11am tomorrow , and tickets can be pre-purchased at  ticketek.com.au
