Mr Coulton welcomed Friday morning's announcement that if the Coalition was re-elected to government at the federal election on July 2, a $25 million federal contribution would be made towards the construction of an integrated cancer centre for Western NSW.

The announcement was made by Deputy Prime Minister and leader of The Nationals, Barnaby Joyce, and deputy leader of The Nationals and Minister for Regional Development, Regional Communications and Rural Health, Fiona Nash, at the party's state conference in Tweed Heads.

Mr Coulton has been advocating for an integrated cancer centre to be incorporated into stages three and four of the NSW government's redevelopment of Dubbo Hospital.

He said the need for such a facility in Western NSW was "very clear".

"I keep hearing that many people are often choosing death over treatment for cancer as the physical and emotional costs of obtaining treatment is an enormous burden not only on patients but also on their families and friends," Mr Coulton said.

"Add to that the estimate that people in Western NSW have a life expectancy eight years below metropolitan areas, in part because people do not have access to specialist centres, it makes the need for this cancer centre very obvious.

"I am very grateful to my colleagues for helping to secure this election promise and to the members of communities right across Western NSW, including Dubbo-based medical specialists and West Dubbo Rotarians, who have helped me to raise awareness of the issues being faced.

"Should the Coalition be re-elected to government at the upcoming election, I will work closely with my state colleague, Deputy Premier Troy Grant, to see this cancer centre come to fruition."

State Member for Dubbo and Deputy Premier Troy Grant welcomed the announcement that a re-elected federal Coalition government would provide $25 million towards a cancer centre for Dubbo.

"I congratulate federal Member for Parkes Mark Coulton, Dubbo West Rotary and all involved on the local campaign to bring a cancer centre to Dubbo on this fantastic news," he said.

"The NSW Government commits to doing our part to make a cancer centre for Dubbo a reality.

"After the July 2 federal election if the federal Liberal and Nationals government is returned I will sit down with Mark Coulton and the (Western NSW) Local Health District to plan and scope out the remaining funding and timeframe to include the cancer centre in stages three and four of the Dubbo Hospital redevelopment."
