Breath test to detect cancer: Study
 

According to researchers cancer may soon be detectable using a breath test. They are now developing sensors that can detect chemical markers of lung, breast, bowel and prostate cancer in a person's breath. The new portable device has been purported as an “electronic nose” that can detect early cancers. As a cancer grows, the surface of the cells emits chemicals. The research found that sensors – involving gold nanoparticles – could be used to detect these chemicals in the breath.
