Health Desk-- 4th Jan’19: A clinical trial has been launched to see if a breath test could detect the presence of cancer.
Researchers want to find out if signals of different cancer types can be picked up in patterns of breath molecules. The Cancer Research UK team in Cambridge will collect breath samples from 1,500 people, some with cancer.
If the technology is proven, the hope is that breath tests could be used in GP practices to decide if patients need to be referred for more tests.
They could potentially be used alongside blood and urine tests to help doctors detect cancer at an early stage, the researchers said.
There are some promising signs that breath tests could detect pre-cancerous symptoms, but it is not yet clear how accurate they are.
