A group of Australian researchers announced Wednesday a new blood test to detect melanoma in its initial phase. This is the most aggressive form of skin cancer and its incidence is increasing. As a result, the new advance was presented as a "world first" that could save thousands of lives .
The scan could help doctors detect melanoma, a cancer The scientists at Edith Cowan University (ECU), whose work was published in Oncotarget magazine, discovered that the skin was very aggressive before spreading to the rest of the body
The development of the new test This is only the beginning.Now, scientists will have to do clinical badyzes that will take three years to validate the findings and have a test that can be used by physicians.
Consulted by Clarín Gabriela Cinat, Medical Oncologist, Head of the Melanoma Unit and Sarcoma of the Angel Roffo Oncology Hospital, Dependent on the University of Buenos Aires, explained that what Australian scientists have designed is "a test using new technologies that detect antibodies that react against the proteins produced by melanoma". ] "On the basis of statistical methods, they identified the ones that seemed most relevant, comparing the blood of melanoma patients in healthy versus healthy volunteers, and estimated that this test could be useful for Early diagnosis, less biopsies of suspicious lesions, "continues Cinat.
"In Australia, melanoma is a problem C is the country with the highest incidence because of the characteristics of the population and its geographical location," says Argentine expert
To think this as an early detection method, one would have to be evaluated in more people and with more studies . "This method needs to be validated in the framework of clinical studies with enough patients to draw definitive conclusions, which will take a few years, "says the expert.To the test reaches Argentina, it must first demonstrate that it is of convincing utility.Then, if it is approved, it will take a long time to reach the rest of the countries, including ours.
Melanoma in Argentina
According to the latest statistics from the Argentine Society of Dermatology, disseminated by the agen this Telam, is diagnosed annually in the country more than 1,400 new cases while in this 574 people die of this pathology.

"Early detection of this disease is key because it is likely to cure a patient through simple surgery when melanoma is diagnosed at an early stage," says Cinat.
To avoid this, it is necessary to avoid excessive exposure to the sun not recommended between 10 and 16 hours, and mainly in the months that have the letter "R": all except May, June, July and August. Apply sunscreen SPF 15 or 30 or more frequently and during the summer months, wear hats, sunglbades with UV protection and clothing that covers as much skin as possible. And avoid using tanning beds.
The detection of malignant or premalignant lesions is also favored as soon as possible. "For this, it is imperative to periodically consult the dermatologist, even more in the presence of a new mole or modifications of a pre-existing one." The treatment of early lesions is simple and badociated with a very high cure rate ", concludes the specialist.
