Mr Canterbury said 18 years seemed like it was ages ago but being at the Relay for Life "brings it all back like it was yesterday".
He called the relay a "journey of healing and awareness" that had allowed people to "come together and celebrate life itself".
Another survivor, Roz Jamieson, was diagnosed with breast cancer seven years ago and said the support of a co-worker had helped her deal with the diagnosis.
"That changed my whole lifestyle," she said.
"I decided that there was more to life than work. That was the positive side for me."
She had since involved herself in working with children, who she said had given her the support she needed to battle the disease.
"They have been my biggest supporters for the last seven years," she said.
Mrs Jamieson encouraged other women to get checked. "If you want to see your kids grown up, go and get your checks," she said.
Dave and Angel Wilson walked the track hand-in-hand in remembrance of Angel's sister, who died from cancer last year, as well as another sister five years prior.
"I saw two little children walking hand-in-hand, and a grandfather with his grandson," said Mr Wilson. "I think it's absolutely marvellous." Mrs Wilson loved the quirky outfits, saying "everybody really goes out of their way".
