The centre is not a physical building, but rather has been established as a care pathway.
A spokesperson for NHS Dumfries and Galloway explained: “It enables clinicians to refer patients to this facility in complex instances where there is a suspicion of cancer, but symptoms do not wholly meet the criteria within the Scottish Referral Guidelines for Suspected Cancer.
“Where they do, those patients will continue to be referred to the appropriate dedicated services at Dumfries and Galloway Royal Infirmary.”
The opening of new centres was a commitment in the SNP manifesto prior to last month’s Scottish Parliament election.
She said: “The fact the centre has opened so quickly is testament to the Scottish Government’s commitment to implementing its manifesto here in South Scotland and indeed nationally.
“It will be vital in ensuring people across our region have quick referrals for cancer diagnoses and in ensuring people receive treatment quickly, which is vital in the successful treatment of cancer.
"I will continue to monitor the progress of this work and ensure other manifesto commitments – including to our transport infrastructure, natural environment and education – are progressed at pace.”
