Lyn Smith from the Rotary Club of Dubbo West and Frances Peters-Little from the not-for-profit Jimmy Little Foundation started the Cancer Centre for Dubbo Hospital Facebook page on April 4.

The page has already received more than 2600 likes from supporters located throughout central, western, southern and northern NSW, Sydney, Newcastle, Wollongong, Canberra, Melbourne and Brisbane.

"The response has been tremendous," Lyn Smith told the Daily Liberal.

"The page was set up to encourage lively discussion about and active support for a new cancer centre at Dubbo.

"People are sharing personal stories and talking about why a dedicated cancer centre is urgently needed in Dubbo.

"We want to keep the momentum going to push a 'paper' petition which should be ready to take to the public by the beginning of May.

"The petition calling for funding for a cancer centre at Dubbo Hospital is being prepared in a way that will be acceptable to both the state and federal Parliaments."

The Rotary Club of Dubbo West started pushing for improved cancer services at Dubbo Hospital last year.

Around the same time the Jimmy Little Foundation initiated an online petition on the Change.org website asking federal Health Minister Sussan Ley to fund at PET-CT scanner at Dubbo Hospital.

The petition pointed to worrying statistics about cancer mortality rates, the importance of early detection and difficulties people living in rural and remote areas faced in obtaining diagnosis and treatment.

Frances Peters-Little said the online action attracted hundreds of signatures and generated "fantastic" comments.

"Member for Parkes Mark Coulton has advised it would be more beneficial to have a petition with signatures collected on paper," Ms Peters-Little said.

"A lot of people have been speaking out about the need for improved cancer diagnosis and treatment facilities at Dubbo Hospital and the wide reach of social media is allowing us to involve more and more people.

"I am about to start a new Facebook campaign encouraging people to take selfies with signs calling for a cancer centre at Dubbo.

"Taking and sharing the selfie photos will give people a way of being actively involved in a very important campaign," Ms Peters-Little said.
