Wellington's Tracey Brown is the first patient at Dubbo's Western Cancer Centre

Wellington's Tracey Brown is the first person to receive radiation at the $35 million facility.

The cancer centre opened to patients on September 20, with the clinic rooms and reception opening first. That was followed by the new chemotherapy treatment spaces and radiation therapy, which opened on October 19. The PET-CT scanner on the ground floor - one of only a handful in NSW - will open at full capacity in the coming months.

Mr Brown is in his second week of treatment for prostate cancer.

"They said 'you're lucky, you'll be going to Dubbo for your treatment, you don't have to go to Orange'," he said.

"It was like winning the lottery for me, it really was."

One of the benefits for Mr Brown was that he was able to go home after his treatment.

And he's positive it'll all be best for the best.

"All being well, I'll be cured. I'm sure I will be, I've got great faith in everyone," Mr Brown said.

Regional Health Minister David Gillespie and Federal Member for Parkes Mark Coulton toured the newly-opened facility at Dubbo Hospital on Wednesday. They also spoke to Mr Brown.

Mr Coulton said it was wonderful to see the Western Cancer Centre complete and open to patients.

"After years of campaigning for this centre, it's so exciting to be here today to see it in action," he said.

Mr Coulton said it was heartening to see how it was already benefitting people like Mr Brown.

"Living only 30 minutes away from the new Cancer Centre, and requiring treatment for prostate cancer every day for four weeks, Tracey was able to be treated in the morning and be back home for lunch, making the whole experience much more positive," he said.

"This is exactly why this facility is so important - it means regional people no longer have to travel to metropolitan centres to access the treatment they need and deserve."

Dr Gillespie said local treatment was "one less burden" for cancer patients.

"Additionally, having a strong local hospital helps to attract more doctors, nurses and health professionals to the region, as it gives them with more exposure to new technologies and increases their range of clinical skills," he said.

The cancer centre will support 70 jobs including medical and allied health roles.

Mr Coulton said he was looking forward to celebrating with all who made the centre happen at the official opening early next year.

The facility was jointly funded with $25 million from the federal government and $10 million from the state.
