A low-cost electronic "nose" designed to detect stomach cancer molecules in the breath can also spot signatures of lesions that herald the disease, according to a study published on Monday. The Israeli-designed tester uses gold nano-particles to detect so-called volatile organic compounds (VOC) that are a tiny telltale in the breath of cancer patients. Each method was used to screen breath samples taken from 484 volunteers in Latvia, 99 of whom had already been diagnosed with stomach cancer but had not yet been treated for it. Both methods accurately spotting those with the cancer, as well as the "breath prints" of high-risk patients who had lesions that often develop into gastric tumours.
