According to a study published in the British Journal of Cancer is possible to use a kind of "electronic nose" able detect various types of cancer through a simple breath test.
Preliminary tests showed that the team could identify chemical signals from the disease in the breath of patients with lung cancer or head and neck. About 80 volunteers participated in the research conducted at the Instituto Tecnologico Israel, known as the Technion. Of these 22 had various types of head and neck cancer, 24 suffered from lung cancer and 36 were healthy. The prototype "electronic nanonariz" uses a chemical method to detect signs of cancer in the breath.
experts are confident that this test may in future be used in consultation with a doctor to provide immediate diagnosis. Technion researchers running the project are especially dedicated to study the types of head and neck cancer. These evils often diagnosed late, making them more difficult to treat successfully. These include cancers of the salivary glands, lip, mouth, nose, larynx and hypopharynx.
Hossam Haick, principal investigator of the Technion, said: "There is an urgent need to develop new ways to detect the types of head and neck cancer since the diagnosis of the disease is complicated and requires specialized tests." According to him, "We have shown that a simple breath test can detect patterns of molecules present in patients with cancers of head and neck." Haick specified that, however, the study is in preliminary stages.
