Blood tests are the latest tool in cancer treatment. By taking blood, scientists can detect changes in DNA that can help to assess the presence of cancer cells in the body.
A blood test with the ability to detect five different forms of cancer by looking for abnormal DNA signatures may be close to becoming a reality.
Researchers were able to identify womb, lung, stomach, colon and breast tumours from normal tissue by the DNA signature around the gene ZNF 154.
There is hope that the potential of this diagnostic technique will lead to earlier diagnosis in people resulting in a higher survival rate.
The research has been carried out by the National Human Genome Research Institutes in the US and published by the Journal of Molecular Diagnostics.
