A biopsy is the only reliable way to diagnose skin cancer, but having good
confidence that a lesion is cancerous before a biopsy can reduce the number of
needless biopsies performed.
A new tool invented by scientists at University of Texas at Austin uses three different mechanisms to image a lesion, potentially providing a new way to spot suspected tumors. It's currently undergoing pilot clinical trials.
The device utilizes Raman spectroscopy, diffuse reflectance spectroscopy, and laser-induced fluorescence spectroscopy at the same time to peer into the lesion.
Readings take about five seconds to function using the probe which is only about the size of a pen. It's connected to a computer that does the image processing. The probe is cheap to manufacture, so if clinical trials pan out positively for the new device, the device will hit the medical industry soon.
