The state's health minister Jillian Skinner will not comment on the need for a second full-time Oncology nurse at Cowra Hospital, instead she referred the matter to the local health district.
A spokesman for Ms Skinner said the Western NSW Local Health District was best placed to answer questions about staffing levels in the unit.
The Cowra Guardian had put questions to Ms Skinner after hundreds of letters were sent to her via the Cowra and District Cancer Action Group's campaign for a second full-time Oncology nurse at Cowra Hospital's Oncology unit.
In response, the Western NSW Local Health District said the current arrangements at Cowra Hospital's Oncology clinic meet the demand for the service.
In a statement, Western NSW Local Health District Director of Nursing and Midwifery Joy Adams said: "The demand for this service has increased steadily over the past three years and the clinic hours have been extended to four days per week thanks to extra funding provided by Cowra Health Service".
"The Western NSW Local Health District is committed to providing an Oncology service in Cowra. Some cancer patients, who require a higher level of treatment, will still be required to travel for their treatment.
"The Western NSW Local Health District has acknowledged the concerns of the Cowra and District Cancer Action Group and has developed a plan to ensure that there will be an accredited nurse on site at the Oncology clinic who will be able to provide relief during periods of leave to ensure continuity of the service."
