Nanotech breath test could detect lung cancer early

A sensor made with gold nanoparticles can detect lung cancer in a patient's breath and may offer a diagnosis before tumours show up on an x-ray, according to a Reuters India article.

The device, which the developers say would be cheap enough for everyday use by family doctors, detected lung cancer with 86 percent accuracy and may offer a way to screen for a disease not usually diagnosed until it has spread and is no longer curable, according to the article.

Hossam Haick, one of the scientists working on the sensor, said he hoped it could soon allow doctors to have a simple test at hand to screen people during routine appointments, according to the article.
