Scientists at the Edith Cowan University (ECU), Australia, have developed a blood test to detect melanoma in its early stages.
The blood test trial was carried out on 105 people with melanoma and a control group of 104 healthy individuals. The test detected early-stage melanoma in 79 per cent of cases.
According to the scientific team, patients who have their melanoma detected in its early stage have a five-year survival rate between 90-99 per cent, whereas if it is not caught early and it spreads around the body, the five-year survival rate drops to less than 50 per cent.
Melanoma is currently identified through a visual scan of an affected skin area and then a biopsy is conducted on the area. But these biopsies are invasive and costly, with previous research showing that the Australian health system spends $201 million on melanoma each year with an additional $73 million on negative biopsies.
The new blood test detects the autoantibodies produced in the body in response to the melanoma. This test would serve as a tool to detect melanoma in its early stages before it spreads throughout the body.
