Melanoma, a portable, painless device identifies it without biopsies

A small, fast and highly accurate device detects melanoma with the same sensitivity as hospital diagnostics. It can be the turning point for routine visits.

The researchers of the Stevens Institute of Technology work on a low-cost, portable device that could halve the number of unnecessary biopsies and provide dermatologists and other frontline doctors with immediate access to lab tests on melanoma, the ever-increasing malignant skin cancer.

Negar Tavassolian - melanoma

"We don't intend to eliminate biopsies," he said Negar Tavassolian, director of the bio-electromagnetism laboratory. "We just want to provide doctors with additional tools and help them make better decisions."

How does the "anti melanoma" scanner work?

The team's device uses millimeter wave imaging, the same technology used in airport security scanners, to scan a patient's skin.

Because healthy tissue absorbs millimeter wave radiation differently from cancerous tissue, it is theoretically possible to spot a melanoma by comparing the rays reflected by the skin. To put this technology into practice, the researchers used algorithms to integrate data obtained from many different antennas into a single ultra-high-bandwidth image, reducing noise and allowing even the smallest tumors to be quickly identified by scanning each mole. and imperfection.

The team, led by Dr. Amir Mirbeik, used a portable version of their technology to examine 71 patients in a real-life scenario. Result? The method can accurately distinguish benign and malignant lesions in seconds.

Early diagnosis of cancer: do-it-yourself test detects it with 90% accuracy

The device identifies melanoma with a 97% sensitivity and 98% specificity, a competitive rate with the best hospital-grade diagnostic tools.

Fast and most of all portable

There are other advanced imaging technologies that can detect skin cancers, but they are large and expensive machines that are not available in the clinic. The turning point is that the diagnosis of melanoma can be done with a low-cost device: small, very fast and as easy to use as a mobile phone.

Whatever Tavassolian says, because the technology delivers results in seconds, it could one day totally change routine checks. Doctors could get lightning-fast and accurate diagnoses of melanoma by treating more patients.

The next steps

Now we need to "pack" this material into an integrated circuit. Immediately after, start with a mass production: soon we will see millimeter wave diagnostics for less than 100 euros. A gamble by 2025, but it will probably take even less: about two years.

Later, big data and machine learning will allow people to use such a tool to keep their skin in check every day. Even alone, when they want.

Between quick diagnostics, effective vaccines e monitoring patch melanoma seems to be numbered in years.
