'Biomedical tattoo' might catch cancer early

[Posty]

Often, cancer goes undetected until its advanced stages, when treating it becomes very difficult and the outlook less promising. But researchers from Switzerland are developing an implant that could alert "wearers" to the presence of cancer early on.

 

Recently, the media has been inundated with the news of "smart tattoos" — developed by researchers from Harvard University in Cambridge, MA.

They help to monitor health using biosensitive ink that changes color following the modifying composition of the body's interstitial fluid.

Now, Prof. Martin Fussenegger — of the Department of Biosystems Science and Engineering at Eidgenössische Technische Hochschule Zürich in Switzerland — alongside a team of researchers, has developed the prototype of another such "tattoo" for a precise purpose:

detecting the possible presence of cancerous cells early on.

Numerous types of cancer are diagnosed late, which diminishes the efficacy of treatment and might mean that people will likely not see positive long-term health outcomes.

it 'lights up' could alert its 'wearer' to early signs of cancer.
