Scientists can sniff out 17 diseases from a single breath sample


When you exhale you breathe out a bunch of different things – mainly nitrogen, carbon dioxide, and oxygen – but there are also more than 100 types of volatile chemical components that come along.

Researchers found each of the 17 diseases that they searched were produced a different ‘breathprint’ – a different amount and combination of 13 different VOCs – that could allow them to accurately pinpoint if a participant had one of these disease or not:

  • lung cancer
  • colorectal cancer
  • head and neck cancer
  • ovarian cancer
  • bladder cancer
  • prostate cancer
  • kidney cancer
  • gastric cancer
  • Crohn’s disease
  • ulcerative colitis
  • irritable bowel syndrome
  • idiopathic Parkinson’s
  • atypical Parkinsonism
  • multiple sclerosis
  • pulmonary arterial hypertension
  • pre-eclampsia
  • chronic kidney disease.
