Queensland researchers have developed a blood test that could reduce the amount of chemotherapy some cancer patients need.
Professor Maher Gandhi from the Queensland Institute of Medical Research (QIMR) says a new blood test has been developed to monitor those with Hodgkin's lymphoma.
Professor Gandhi says patients could be monitored more closely and possibly taken off chemotherapy sooner.
"At the moment the best way to do that is to do scans, like CT scans and PET scans, which tell you how the tumour is shrinking," he said.
"But it is impracticable to do a scan on every visit so a blood test would be very helpful in monitoring the patient.
"Often a lot of the tests and discoveries are about new treatments and that's very important, but I think we also need to be thinking about discoveries that may actually mean less treatment for patients and better value for the dollar."
It is believed the blood test could become available to the public within four years.
