National Taiwan University has developed a semiconductor chip that enables to detect a cancer by analyzing breath.
The details of the technology will be announced at International Solid-State Circuits Conference (ISSCC) 2015, an academic conference on semiconductor integrated circuit technologies, which will take place from Feb 22 to 26, 2015, in San Francisco.
Gas chromatography is drawing attention as a non-invasive method to detect cancers by analyzing the patient's breath. This time, a research group at the university developed a SoC (system on a chip) for realizing a portable gas chromatography system that can detect cancer-derived volatile organic compounds.
The SoC is equipped with a separation column and preconcentrator formed by a MEMS (micro electro mechanical systems) process in addition to a CMOS-based gas detector, low-noise output front end and control unit and can detect organic compounds with a concentration of 15ppb or higher. The size and current consumption of the chip are 3.3 x 3.6mm and 1mA or lower, respectively. In a test, the research team used the chip and detected seven kinds of organic compounds derived from lung cancer.

Interestingly dogs are used for the same benefit. Canines were trained to detect known cancer patients and then identify potential early recognition of new cancer patients simply by sniffing the patients breath.

Very cool.

This is great news!! We can detect lung cancer annually without LDCT scans that are harmful and very costly.
Lung cancer is the number one cause of cancer deaths in men and women today. More people die from lung cancer than from all the other cancers combined
Early detection is key to survivorship Hope this tool becomes available to everyone,.
