Simple Blood Test Could Be Used to Detect Breast Cancer

Researchers at the University of Western Australia are working on a quick, simple, and less invasive blood-based test that can detect breast cancer progression or relapse much earlier than current methods such as mammogram, MRI, or biopsy. "Our research examines cancer 'exosomes' which are parts of the cancer shed into the body fluids that can drive the spread and aggressiveness of cancer. These exosomes, or biomarkers of disease, can be detected during routine blood tests and as early studies show exosome levels increase with more aggressive cancers, our research will monitor exosome levels in patients' blood during treatment," says Dr Katie Meehan from UWA's School of Pathology and Laboratory Medicine. "We hope to show that when exosomes become undetectable in the blood, this indicates the cancer is gone or if exosomes remain in the blood, this may identify a cancer at risk of returning."

    00:00:01 The research is to develop a blood test that can detect small fragments or little seeds if you like of the cancers that do break off from cancers and then go into our blood. It would be a simple blood test so that would mean that people all over the state of Western Australia or in fact all over Australia in rural communities or what have you dont have to go to specialised facilities to have their blood drawn because what can happen is once the blood is drawn it can then be sent to a central testing which the test can then be carried out then. We can do better for our breast cancer patients and they deserve peace of mind and this particular test will allow us to measure very very low levels of cancer in the blood so that means that before a cancer has the chance to really settle in we can pick it up at a really early

    00:00:53 stage. Also it means that women that have survived breast cancer it will give them some peace of mind that we can test hopefully on a regular basis that the cancer is not coming back. And it's ongoing across Australia and it's really important we in Western Australia keep up and punch above our weight and we are.
