Can a blood test find melanoma?
Scientists at Edith Cowan University in Western Australia tested for antibodies.
These antibodies are typically created in response to melanoma.
Researchers studied 245 people. Approximately half with early stage melanoma and half healthy volunteers.
The Researchers published their findings this summer in Oncotarget. Their 3 year study found that a combination of 10 antibodies are the best indicators of melanoma. The study had a 79 to 84% accuracy.
These Australian researchers may be the first to create a blood test to detect melanoma.
But to make this a useful diagnostic tool, the blood test needs to have a 90% accuracy rate.
And once detected, the patient would need a biopsy to confirm the diagnosis. But a non-invasive blood test would allow for earlier diagnosis and that could save lives.
