Breath test could help detect cancers.
The study examined the breath of 177 volunteers with different stages of lung, breast, bowel, or prostate cancer and those who were healthy. The patients with cancer had already been diagnosed by screenings or biopsies but had not yet begun treatment.
According to the researchers, as a cancer grows, the surface of cells emits chemicals, and the sensors can detect these chemicals in the breath. Further tests with larger samples are needed to confirm whether breath can be used in the detection of cancer. However, the test has the potential to aid in the early detection of cancers as well as improving treatments for cancers.
