American researchers develop a fast and accurate test to detect cancer

A team of researchers at the University of Texas at El Paso has successfully developed a revolutionary device capable of detecting cancer markers in less than one hour — a breakthrough that could transform early diagnosis methods for the disease.

The new device, called “PiPP”, is based on a simple and low-cost technology. It combines paper similar to coffee filters with a lightweight plastic structure to create a highly precise testing platform. This platform can detect cancer markers in blood samples even at extremely low concentrations — offering sensitivity up to ten times greater than that of current analytical devices.

In its experimental phase, PiPP targets two types of cancer biomarkers:

Carcinoembryonic antigen (CEA), commonly associated with colorectal cancer.

Prostate-specific antigen (PSA), an indicator of potential prostate cancer.

The significance of this innovation lies in its ability to detect the disease in its earliest stages, when these biomarkers are rare and difficult to identify using conventional methods.

This device is expected to mark a major leap forward in early medical screening, combining speed, accuracy, and affordability. It could make cancer detection more widely accessible, increase survival rates, and reduce deaths caused by delayed diagnosis.
