This year, the 20-year-old had a massive series of operations to replace his knee and 25 centimetres of his femur with metal after months of chemotherapy to battle a form of bone cancer.

On Saturday, only four months since he was back on his own two feet, he was walking through Cook Park to support an organisation which supported him through his cancer battle in Sydney.

CanTeen's open day at Cook Park on Saturday was aimed to let people know about CanTeen, and Mr Tarleton said their support had been invaluable during 18 months of hospital stays and travelling to Sydney.

CanTeen help give cancer sufferers and those who have parents or siblings going through cancer a support network, which includes camps and activities with other people in the same boat.

"When I've been in hospital, having someone to talk to for hours on end was good," Mr Tarleton said.

"[CanTeen] have been really helpful. During my treatment I didn't get to talk to many people, mainly people from Orange but I didn't see many of them so it was good to talk to people and meet other people going through the same thing."

He said the camps and activities were "really good", and meeting people going through the same thing was a massive boost.

"It's different from other people who can be sympathetic but it's something you're going through at the same time. It's good to meet new friends," he said.

The organisation's trek from Sydney to the Central West - where there are between 15 and 25 families from Narromine to Lithgow which use the service - was appreciated my Mr Tarleton, who is now cancer free.

"It's good to see them come out and give support to Western areas," he said.

Organiser Emma Woods said the aim of the open day was to connect with families who might use their service and to alert the health sector to their existence.

"The purpose of being out here is to connect with a huge group of people and make people realise we exist and we're free," Ms Woods said.

"We wanted to come out and connect with the Central West community and let families know we're here to support them and provide support services for free."

She said connecting young people going through treatment or siblings' treatment was "often a first" for people from regional areas.

"Often they'll be the only person in their class who has had a close family member die of cancer or have gone through cancer treatment themselves or any number of things," she said.
