Device Detects Disease Even Before Tumours Become Visible In X–Rays
Scientists working on a breath test to detect cancer said they were now able to identify different types of the disease, in research to be published on Wednesday.

Their preliminary results, to be printed in the British Journal of Cancer, showed the researchers’ sensors could distinguish whether a patient had lung, breast, bowel or prostate cancer, irrespective of age, gender or lifestyle.

Previous research, conducted at the Technion Israel Institute of Technology in the northern port city of Haifa, found that they could largely distinguish between the breath of healthy patients and cancer sufferers.

The sensor uses gold nanoparticles to detect levels of socalled volatile organic compounds – measured in a few parts per billion – that become more elevated in cancer patients. The device could provide an early warning system that flags the disease before tumours become visible in X–rays.

Technion’s professor Abraham Kuten co–authored the study published on Wednesday. "This study shows that an ‘electronic nose’ can distinguish between healthy and malignant breath, and can also differentiate between the breath of patients with different cancer types," he said.

"If we can confirm these initial results in large–scale studies, this new technology could become a simple tool for early diagnosis of cancer along with imaging."

The study examined the breath of 177 volunteers, including healthy people and patients already diagnosed with different stages of the four types of cancer. As a cancer grows, the surface of cells emits chemicals. The study found that sensors could be used to detect these chemicals in the breath. AFP

Detect oral cancer in under 20 mins
Researchers are on the verge of developing a new test for oral cancer that could be done by using a brush to collect cells from a patient’s mouth. Experts from the University of Sheffield are developing the new method that could provide an accurate diagnosis in less than 20 minutes for lesions where there is a suspicion of oral cancer. The new test would involve removing cells with a brush, placing them on a chip, and inserting the chip into the analyzer, leading to a result in 8–10 minutes.
