Scientists claim they have a breath test machine that detects cancer in just seven minutes, and it could be in use within two years as it begins clinical trials in Britain.
The test uses an "electronic nose" able to detect chemicals produced by cancers.
Human trials are due to take place this autumn at two NHS hospitals and two in the US, involving hundreds of patients, Daily Mail reported.
The non-invasive tests, initially targeting lung cancer, will see patients breathing through a mouthpiece for a minute, with analysis being sent to a supercomputer.
The device detects chemicals produced by each cancer, known as "volatile organic compounds", and could help spot cancer at very early stages.
