A portable device that can detct cancer cell easily

Researchers from University of Tarragona in Spain have developed a device that can diagnosis of cancer by detecting tumours
Cell in blood.
This device is also cheap and easy to carry.therefore it will be  very helpful for detecting, treatment or monitoring of cancer cell.
The device can accurately determine a patient's level of health and monitor cancer quickly, cheaply , and effectively, researchers said.
The portable device uses two systems in miniature:a flow system and an optical system.

The first causes the blood cells to flow in alignment while the  second uses two optic fibers( a laser diode and a photodetector) to analyse and count cancerous or non-cancerous cells researchers said.
The ratio between the two reveals how the cancer is progressing.
The finding were published in the journal scientific reports.
